And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS diff --git a/libburn/branches/1.1.6/COPYRIGHT b/libburn/branches/1.1.6/COPYRIGHT new file mode 100644 index 00000000..689eaeba --- /dev/null +++ b/libburn/branches/1.1.6/COPYRIGHT @@ -0,0 +1,18 @@ +Derek Foreman and Ben Jansens +Copyright (C) 2002-2006 Derek Foreman and Ben Jansens +Mario Danic , Thomas Schmitt +Copyright (C) 2006-2011 Mario Danic, Thomas Schmitt + + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License version 2 or later + as published by the Free Software Foundation. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/libburn/branches/1.1.6/Makefile.am b/libburn/branches/1.1.6/Makefile.am new file mode 100644 index 00000000..a2cd55c9 --- /dev/null +++ b/libburn/branches/1.1.6/Makefile.am @@ -0,0 +1,231 @@ + +# ts A90315 : LIBBURNIA_PKGCONFDIR is defined OS specific in acinclude.m4 +# was: pkgconfigdir=$(libdir)/pkgconfig +pkgconfigdir=$(LIBBURNIA_PKGCONFDIR) + +libincludedir=$(includedir)/libburn + +lib_LTLIBRARIES = libburn/libburn.la +ACLOCAL_AMFLAGS = -I ./ + +## ========================================================================= ## + +# Build libraries +libburn_libburn_la_LDFLAGS = \ + -version-info $(LT_CURRENT):$(LT_REVISION):$(LT_AGE) +# This causes undesired .o names +# configure.ac appends -D options to variable CFLAG +### libburn_libburn_la_CFLAGS = $(LIBBURN_DVD_OBS_64K) +libburn_libburn_la_LIBADD = $(LIBBURN_ARCH_LIBS) $(THREAD_LIBS) +libburn_libburn_la_SOURCES = \ + libburn/async.c \ + libburn/async.h \ + libburn/back_hacks.h \ + libburn/cleanup.c \ + libburn/cleanup.h \ + libburn/crc.c \ + libburn/crc.h \ + libburn/debug.c \ + libburn/debug.h \ + libburn/drive.c \ + libburn/drive.h \ + libburn/ecma130ab.c \ + libburn/ecma130ab.h \ + libburn/error.h \ + libburn/file.c \ + libburn/file.h \ + libburn/init.c \ + libburn/init.h \ + libburn/libburn.h \ + libburn/libdax_audioxtr.h \ + libburn/libdax_audioxtr.c \ + libburn/libdax_msgs.h \ + libburn/libdax_msgs.c \ + libburn/mmc.c \ + libburn/mmc.h \ + libburn/null.c \ + libburn/null.h \ + libburn/options.c \ + libburn/options.h \ + libburn/os.h \ + libburn/read.c \ + libburn/read.h \ + libburn/sbc.c \ + libburn/sbc.h \ + libburn/sector.c \ + libburn/sector.h \ + libburn/sg.c \ + libburn/sg.h \ + libburn/source.h \ + libburn/source.c \ + libburn/spc.c \ + libburn/spc.h \ + libburn/structure.c \ + libburn/structure.h \ + libburn/toc.c \ + libburn/toc.h \ + libburn/transport.h \ + libburn/util.c \ + libburn/util.h \ + libburn/write.c \ + libburn/write.h \ + version.h + +## libburn/sg-@ARCH@.c \ + +libinclude_HEADERS = \ + libburn/libburn.h + +install-exec-hook: + $(LIBBURNIA_LDCONFIG_CMD) "$(DESTDIR)$(libdir)" || echo 'NOTE: Explicite dynamic library configuration failed.

This capability together with our burn capability +makes possible a single binary application which covers all steps of image +composition, updating and writing. Quite unique in the Linux world. + +The project components (list subject to growth, hopefully): + +- libburn is the library by which preformatted data get onto optical media. + It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or + /dev/srM or /dev/hdX (e.g. on kernel 2.6). + libburn is the foundation of our cdrecord emulation. Its code is + independent of cdrecord. Its DVD capabilities are learned from + studying the code of dvd+rw-tools and MMC-5 specs. No code but only + the pure SCSI knowledge has been taken from dvd+rw-tools, though. + +- libisofs is the library to pack up hard disk files and directories into a + ISO 9660 disk image. This may then be brought to CD via libburn. + An own ISO 9660 extension stores ACLs, xattr, and MD5 of file + content. + +- libisoburn is an add-on to libburn and libisofs which coordinates both and + also allows to grow ISO-9660 filesystem images on multi-session + media as well as on overwriteable media via the same API. + All media peculiarities are handled automatically. + It also contains the methods of command oriented application + xorriso and offers them via a C language API. + +- cdrskin is a limited cdrecord compatibility wrapper for libburn. + cdrecord is a powerful GPL'ed burn program included in Joerg + Schilling's cdrtools. cdrskin strives to be a second source for + the services traditionally provided by cdrecord. Additionally it + provides libburn's DVD capabilities, where only -sao is compatible + with cdrecord. + cdrskin does not contain any bytes copied from cdrecord's sources. + Many bytes have been copied from the message output of cdrecord + runs, though. + See cdrskin/README for more. + +- xorriso is an application of all three libraries which creates, loads, + manipulates and writes ISO 9660 filesystem images with + Rock Ridge extensions. Manipulation is not only adding or + overwriting of files but also deleting, renaming, attribute + changing, incremental backups, activating boot images, and + extracting of files from ISO images to disk. There is also a + sparse emulation of cdrecord and a more laborate one of mkisofs. + All features of xorriso are also available via a C language API + of libisoburn. + A static compilation of xorriso and the libraries is dedicated + to the GNU Operating System. See xorriso/README_gnu_xorriso . + +- "test" is a collection of application gestures and examples given by the + authors of the library features. The burn API example of libburn + is named test/libburner.c . The API for media information inquiry is + demonstrated in test/telltoc.c . + Explore these examples if you look for inspiration. + +We strive to be a responsive upstream. + +Our libraries are committed to maintain older feature sets in newer versions. +This applies to source code headers (API) as well as to linkable objects (ABI). +The only exception from this rule is about non-release versions x.y.*[13579] +which are allowed to introduce new features, change those new features in +any way and even may revoke such new features before the next release of +x.y.*[02468]. As soon as it is released, a feature is promised to persist. + +SONAMES: +libburn.so.4 (since 0.3.4, March 2007), +libisofs.so.6 (since 0.6.2, February 2008), +libisoburn.so.1 (since 0.1.0, February 2008). + +Applications must use 64 bit off_t. E.g. by defining +#define _LARGEFILE_SOURCE +#define _FILE_OFFSET_BITS 64 +or take special precautions to interface with the libraries by 64 bit integers +where the .h files prescribe off_t. To reduce libburn's off_t size to 32 bit +will keep it from processing tracks of more than 2 GB size. + + +------------------------------------------------------------------------------ +Project history as far as known to me: + +- Founded in 2002 as it seems. See mailing list archives + http://lists.freedesktop.org/archives/libburn/ + The site of this founder team is reachable and offers download of a + (somewhat outdated) tarball and from CVS : + http://icculus.org/burn/ + Copyright holders and most probably founders: + Derek Foreman and Ben Jansens. + +- I came to using libburn in 2005. Founded the cdrskin project and submitted + necessary patches which were accepted or implemented better. Except one + remaining patch which prevented cdrskin from using vanilla libburn from CVS. + The cdrskin project site is reachable and offers download of the heavily + patched (elsewise outdated) tarball under the name cdrskin-0.1.2 : + http://scdbackup.sourceforge.net/cdrskin_eng.html + It has meanwhile moved to use vanilla libburn.pykix.org , though. + Version 0.1.4 constitutes the first release of this kind. + +- In July 2006 our team mate Mario Danic announced a revival of libburn + which by about nearly everybody else was perceived as unfriendly fork. + Derek Foreman four days later posted a message which expressed his + discontent. + The situation first caused me to publically regret it and then - after i + got the opportunity to move in with cdrskin - gave me true reason to + personally apologize to Derek Foreman, Ben Jansens and the contributors at + icculus.org/burn. Posted to both projects: + http://lists.freedesktop.org/archives/libburn/2006-August/000446.html + http://mailman-mail1.webfaction.com/pipermail/libburn-hackers/2006-August/000024.html + +- Mid August 2006 project cdrskin established a branch office in + libburn.pykix.org so that all maintainers of our tools have one single place + to get the current (at least slightely) usable coordinated versions of + everything. + Project cdrskin will live forth independendly for a while but it is committed + to stay in sync with libburn.pykix.org (or some successor, if ever). + cdrskin is also committed to support icculus.org/burn if the pending fork + is made reality by content changes in that project. It will cease to maintain + a patched version of icculus.org/burn though. Precondition for a new + release of cdrskin on base of icculus.org/burn would be the pending + "whitelist patch" therefore. + I would rather prefer if both projects find consense and merge, or at least + cooperate. I have not given up hope totally, yet. + I, personally, will honor any approach. + +- 2nd September 2006 the decision is made to strive for a consolidation of + copyright and a commitment to GPL in a reasonable and open minded way. + This is to avoid long term problems with code of unknown origin and + with finding consense among the not so clearly defined group of copyright + claimers and -holders. + libisofs is already claimed sole copyright Mario Danic. + cdrskin and libburner are already claimed sole copyright Thomas Schmitt. + Rewrites of other components will follow and concluded by claiming full + copyright within the group of libburn.pykix.org-copyright holders. + +- 16th September 2006 feature freeze for release of libburn-0.2.2 . + +- 20th September 2006 release of libburn-0.2.2 . + +- 26th October 2006 feature freeze for cdrskin-0.2.4 based on libburn-0.2.3 . + This version of cdrskin is much more cdrecord compatible in repect + to drive addressing and audio features. + +- 30th October 2006 release of cdrskin-0.2.4 . + +- 13th November 2006 splitting releases of libburn+cdrskin from libisofs. + +- 24th November 2006 release of libburn-0.2.6 and cdrskin-0.2.6 . cdrskin has + become suitable for unaware frontends as long as they perform only the core + of cdrecord use cases (including open-ended input streams, audio, and + multi-session). + +- 28th November 2006 the umbrella project which encloses both, libisofs and + libburn, is now called libburnia.

Now the scope + is widened to a first class of DVD media: overwriteable single layer types + DVD-RAM, DVD+RW, DVD-RW. This is not a cdrecord emulation but rather inspired + by dvd+rw-tools' "poor man" writing facility for this class of media. + Taking a bow towards Andy Polyakov. + +- 11th February 2007 version 0.3.2 covers sequential DVD-RW and DVD-R with + multi-session and with DAO. + +- 12th March 2007 version 0.3.4 supports DVD+R and thus covers all single layer + DVD media.

No extra blanks. +A first character '#' marks a comment, empty lines are ignored. + +Example content of a startup file: +# This is the default device +dev=0,1,0 + +# Some more options +fifo_start_at=0 +fs=16m + + + Audio CD + +Lorenzo Taylor enabled option -audio in cdrskin (thanks !) and reports neat +results with audio data files which are : + headerless PCM (i.e. uncompressed) + 44100 Hz sampling rate + 16 bits per sample + stereo (2 channels) + little-endian byte order with option -swab, or big-endian without -swab + +Files with name extension .wav get examined wether they are in Microsoft WAVE +format with above parameters and eventually get extracted by cdrskin itself. +In the same way files with name extension .au get examined wether they are +in SUN's audio format. For both formats, track format -audio and eventual +endianness option -swab are enabled automatically. + +Any other formats are to be converted to format .wav with above parameters +or to be extracted as raw CD track data by commands like those given above +under "Usage examples". Those raw files need option -audio and in most cases +option -swab to mark them as little-endian/Intel/LSB-first 16-bit data. +Incorrect endianness setting results in random noise on CD. + +I myself am not into audio. So libburn-hackers@pykix.org might be the +best address for suggestions, requests and bug reports. + + + DVD+RW , DVD-RAM , BD-RE + +These random access media get treated as blank media regardless wether they +hold data or not. Options -audio and -multi are not allowed. Only one track +is allowed. -toc does not return information about the media content. +Speed is counted in DVD units (i.e. 1x = 1,385,000 bytes/second) or BD units +(1x = 4,495,625 bytes/second). Currently there is no difference between -sao +and -tao. If ever, then -tao will be the mode which preserves the current +behavior. + +BD-RE media need formatting before first use. cdrskin option "blank=as_needed" +recognizes unformatted BD-RE and applies a lengthy formatting run. + +During write operations DVD-RAM and BD-RE automatically apply Defect +Management. This usually slows them down to half nominal speed. If drive +and media produce flawless results anyway, then one can try to reach full +nominal speed by option "stream_recording=on". +In this case bad blocks are not detected during write and not even previously +known bad blocks are avoided. So you have to make your own readability tests +and go back to half speed as soon as the first read errors show up. +Instead of "on" one may also set a start address for stream recording. +Like "stream_recording=100m". This will write slowly to the first 100 MB of +the media and accelerate when writing to higher addresses. + +Option --grow_overwriteable_iso allows -multi (although unneeded), enables +-msinfo and -toc, and makes blank=fast an invalidator for ISO filesystems +on overwriteable media. + +Initial session (equivalent to growisofs -Z): + mkisofs ... | cdrskin --grow_overwriteable_iso blank=fast ... + +Add-on session (equivalent to growisofs -M): + cparms=$(cdrskin dev=/dev/sr0 --grow_overwriteable_iso -msinfo) + mkisofs -C "$cparms" -M /dev/sr0 ... | \ + cdrskin dev=/dev/sr0 --grow_overwriteable_iso ... - + + + DVD-RW , DVD-R , DVD-R DL + +DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state +"Sequential Recording". DVD-R are always in sequential state. DVD-R DL are +always sequential and incapable of multi-session. + +"Sequential" is the state of unused media and of media previously blanked +or written by cdrecord. dvd+rw-format -blank can also achieve this state. +The according cdrskin option is blank=deformat_sequential . +If "Incremental Streaming" is available, then sequential media are capable +of multi-session like CD-R[W]. (But not capable of -audio recording.) +This means they need option -multi to stay appendable, need to be blanked +to be writeable from start, return useable info with -toc and -msinfo, +eventually perform appending automatically. +Without Incremental Streaming offered by the drive, only write mode DAO is +available with sequential DVD-R[W]. It only works with blank media, allows only +one single track, no -multi, and demands a fixely predicted track size. +(growisofs uses it with DVD-R[W] if option -dvd-compat is given.) + +Overwriteable DVD-RW behave much like DVD+RW. "Restricted" refers only to the +granularity of random access and block size which have always to be aligned to +full 32 kB. Sequential DVD-RW are converted into overwriteable DVD-RW by + cdrskin dev=... -v blank=format_overwrite +(Command dvd+rw-format -force can achieve Restricted Overwrite, too.) + +Formatting or first use of freshly formatted DVD-RW can produce unusual noises +from the drive and last several minutes. Depending on mutual compatibility of +drive and media, formatting can yield unusable media. It seems that those die +too on blanking by cdrecord, dvd+rw-format or cdrskin. Perils of DVD-RW. + +There are three DVD-RW formatting variants with cdrskin currently: + +blank=format_overwrite uses "DVD-RW Quick" formatting (MMC-type 15h) +and writes a first session of 128 MiB. This leads to media which are expandable +and random addressable by cdrskin. + +blank=format_overwrite_quickest uses "DVD-RW Quick" formatting (type 15h) too, +but leaves the media in "intermediate" state. In the first session of writing +one may only write sequentially to such a DVD. After that, it gets random +addressable by cdrskin. DVD-ROM drives might show ill behavior with them. + +blank=format_overwrite_full uses preferrably "Full Format" (type 00h). +This formatting lasts as long as writing a full DVD. It includes writing of +lead-out which is said to be good for DVD ROM compatibility. + +De-formatting options are available to make overwriteable DVD-RW sequential: + +blank=deformat_sequential performs thorough blanking of all states of DVD-RW. +blank=all and blank=fast perform the same thorough blanking, but refuse to do +this with overwriteable DVD-RW, thus preserving their formatting. The specs +allow minimal blanking but the resulting media on my drives offer no +Incremental Streaming afterwards. So blank=fast will do full blanking. + +blank=deformat_sequential_quickest is faster but might yield DAO-only media. + + + DVD+R , DVD+R DL , BD-R + +From the view of cdrskin they behave much like DVD-R. Each track gets wrapped +into an own session, though. + +DVD+R DL appear as extra large DVD+R. cdrskin does not allow to set the address +of the layer break where a reading drive might show some delay while switching +between both media layers. + +BD-R are sold unformatted blank. If used without initial formatting then the +drive is supposed to format them to maximum payload size with no Defect +Management (see also above with BD-RE). +If Defect Management is desired then BD-R need to be formatted before the +first attempt to write a session to them. +blank=format_if_needed will detect the situation and eventually apply + default sized Defect Management formatting. +blank=format_defectmgt_* will apply non-default parameters to formatting. + + + Emulated Drives + +cdrskin can use filesystem objects as emulated drives. Regular files or block +devices appear similar to DVD-RAM. Other file types resemble blank DVD-R. +Necessary precondition is option --allow_emulated_drives which is not accepted +if cdrskin took another user identity because of the setuid bit of its access +permissions. +Addresses of emulated drives begin with prefix "stdio:". E.g. + dev=stdio:/tmp/my_pseudo_drive + +For safety reasons the superuser is only allowed to use /dev/null as emulated +drive. See man page section FILES for a way to lift that ban. + + +------------------------------------------------------------------------------ + + Special compilation variations + +All following options of ./configure and cdrskin/compile_cdrskin.sh are +combinable. After runs of ./configure do as next: + make clean ; make + +In some situations Linux may deliver a better write performance to drives if +the track input is read with O_DIRECT (see man 2 open). The API call +burn_os_open_track_src() and the input readers of cdrskin and libburn fifo +can be told to use this peculiar read mode by: + --enable-track-src-odirect + +But often cdrskin option dvd_obs=64k will yield even better performance in +such a situation. 64k can be made default at compile time by + cdrskin/compile_cdrskin.sh -dvd_obs_64k +It can also be enabled at configure time by + ./configure ... --enable-dvd-obs-64k ... + +Alternatively the transport of SCSI commands can be done via libcdio-0.83. +You may install it and re-run libburn's ./configure with option + --enable-libcdio + +You may get a (super fat) statically linked binary by : + cdrskin/compile_cdrskin.sh -static +if your system supports static linking, at all. This will not help with kernels +which do not properly support the necessary low-level interfaces chosen by +your compile-time libraries. + +A size reduced but fully functional binary may be produced by + cdrskin/compile_cdrskin.sh -do_strip + +An extra lean binary with reduced capabilities is created by + cdrskin/compile_cdrskin.sh -do_diet -do_strip +It will not read startup files, will abort on option dev_translation= , +will not have a fifo buffer, and will not be able to put out help texts or +debugging messages. + + +Linux only: + +libburn tries to avoid a collision with udev's drive examination by waiting +0.1 seconds before opening the device file for a longer time, after udev +might have been alarmed by drive scanning activities. +The waiting time can be set at ./configure time with microsecond granularity. +E.g. 2 seconds: + CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=2000000" + ./configure ...options... +Waiting can be disabled by zero waiting time: + CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=0" +Alternatively, libburn can try to be nice by opening the device file, +closing it immediately, waiting, and only then opening it for real: + CFLAGS="$CFLAGS -DLibburn_udev_extra_open_cyclE -DLibburn_udev_wait_useC=500000" + +------------------------------------------------------------------------------ + + System Dependend Drive Permission Examples + +Accessing the optical drives requires privileges which usually are granted +only to the superuser.

If no write mode +is given explicitly then one will be chosen which matches the peculiarities +of track sources and the state of the output media. +.PP +More than one track can be burned by a single run of cdrskin. +In the terms of the MMC standard all tracks written by the same run constitute +a \fBsession\fP. +.br +Some media types can be kept appendable so that further tracks can +be written to them in subsequent runs of cdrskin (see option -multi). +Info about the addresses of burned tracks is kept in a table of +content (TOC) on media and can be retrieved via cdrskin option -toc. +This information is also used by the operating systems' CD-ROM read drivers. +.PP +In general there are two types of tracks: data and audio. They differ in +sector size, throughput and readability via the systems' CD-ROM drivers +resp. by music CD players. With DVD and BD there is only type data. +.br +If not explicitly option -audio is given, then any track is burned as type +data, unless the track source is a file with suffix ".wav" or ".au" and has a +header part which identifies it as MS-WAVE resp. SUN Audio with suitable +parameters. Such files are burned as audio tracks by default. +.PP +While audio tracks just contain a given time span of acoustic vibrations, +data tracks may have an arbitray meaning. Nevertheless, ISO-9660 filesystems +are established as a format which can represent a tree of directories and +files on all major operating systems. Such filesystem images can be +produced by programs mkisofs or genisoimage or xorriso. +They can also be extended by follow-up tracks if prepared properly. +See the man pages of said programs. +cdrskin is able to fulfill the needs about their option -C. +.br +Another type of data track content are archive formats which originally +have been developed for magnetic tapes. Only formats which mark a detectable +end-of-archive in their data are suitable, though. Well tested are +the archivers afio and star. Not suitable seems GNU tar. +.SS +.B Write mode selection: +.br +In general there are two approaches for writing media: +.br +A permissive mode depicted by option +.B -tao +which needs no predicted track size and allows to make use of +eventual multi-session capabilities. +.br +A more restrictive mode +.B -sao +(alias -dao) which usually demands a predictable track size and is not +necessarily capable of multi-session. It may have advantages for some +readers resp. players of the recorded tracks. +.br +If none of the options -dao, -tao or -sao is given then the program will +try to choose a write mode which matches the defined recording job, +the capabilities of the drive and the state of the present media. +.br +So the mentioning of write modes in the following paragraphs and in the +examples is not so much a demand that the user shall choose one explicitly, +but rather an illustration of what to expect with particular media types. +.SS +.B Recordable CD Media: +.br +CD-R can be initially written only once and eventually extended until they +get closed (or are spoiled because they are overly full). After that they are +read-only. Closing is done automatically unless option +.B -multi +is given which keeps the media appendable. +.br +Write mode +-tao allows to use track sources of unpredictable length (like stdin) and +allows to write further sessions to appendable media. +-sao produces audio sessions with seamless tracks but needs predicted track +sizes and cannot append sessions to media. +.br +CD-RW media can be blanked to make them re-usable for another +round of overwriting. Usually +.B blank=fast +is the appropriate option. +Blanking damages the previous content but does not +make it completely unreadable. It is no effective privacy precaution. +Multiple cycles of blanking and overwriting with random numbers might be +needed. +.SS +.B Sequentially Recordable DVD or BD Media: +.br +Currently DVD-RW, DVD-R[DL], DVD+R[DL], and BD-R can be used for the Sequential +recording model. It resembles the model of CD media. Only DVD-RW can be +blanked and re-used from scratch. +.br +DVD-RW are sequential media if they are in state "Sequential Recording". +The media must be either blank or appendable. +Newly purchased DVD-RW and DVD-R media are in this state. +Used DVD-RW get into blank sequential state by option +.B blank=deformat_sequential . +.br +With DVD-R[W] two write modes may be available: +.br +Mode DAO has many restrictions. It does not work with +appendable media, allows no -multi and only a single track. The size of the +track needs to be known in advance. So either its source has to be a disk file +of recognizable size or the size has to be announced explicitly by options +.B tsize= +or +.B tao_to_sao_tsize= . +.br +DAO is the only mode for DVD-R media which do not offer feature 21h Incremental +Streaming (e.g. DVD-R DL). DAO may also be selected explicitly by option +.B -sao . +Program growisofs uses DAO on sequential DVD-R[W] media for maximum +DVD-ROM/-Video compatibility. +.br +The other mode, Incremental Streaming, is the default write mode if +it is available and if the restrictions of DAO would prevent the job. +Incremental Streaming may be selected explicitly by option +.B -tao +as it resembles much CD TAO by allowing track sources of +unpredicted length and to keep media appendable by option +.B -multi . It does not work with DVD-R DL and minimally blanked DVD-RW. +The only restriction towards CD-R[W] is the lack of support for -audio tracks. +Multiple tracks per session are permissible. +.br +The write modes for DVD+R[/DL] and BD-R resemble those with DVD-R except that +each track gets wrapped in an own session. There is no -dummy writing +with DVD+R[/DL] or BD-R. +.br +Quite deliberately write mode -sao insists in the tradition of a predicted +track size and blank media, whereas -tao writes the tracks open ended and +allows appendable media. +.br +BD-R may be formatted before first use to enable the Defect Management which +might catch and repair some bad spots at the expense of slow speed +even with flawless media. +.br +.B Note: +Option -multi might make DVD media unreadable in some DVD-ROM drives. +Best reader compatibility is achieved without it +(i.e. by single session media). +.SS +.B Overwriteable DVD or BD Media: +.br +Currently types DVD+RW, DVD-RW, DVD-RAM and BD-RE can be overwritten via +cdrskin. +.br +Option -audio is not allowed. Only one track is allowed. +Option -multi cannot mark a recognizable end of overwriteable media. +Therefore -multi is banned unless ISO-9660 images shall be expandable by help +of option +.B --grow_overwriteable_iso . +Without this option or without an ISO-9660 filesystem image present +on media, -toc does not return information about the media content and +media get treated as blank regardless wether they hold data or not. +.br +Currently there is no difference between -sao and -tao. If ever, then -tao +will be the mode which preserves the current behavior. +.PP +DVD+RW and DVD-RAM media need no special initial formatting. They offer a +single continuous data area for blockwise random access. BD-RE need +explicit formatting before use. See +.B blank=as_needed +or blank=format_defectmgt . +.br +DVD-RW are sold in state "Sequential Recording". To become suitable for the +Overwriteable DVD recording model they need to get formatted to state +"Restricted Overwrite". Then they behave much like DVD+RW. This formatting +can be done by option +.B blank=format_overwrite . +.br +Several programs like dvd+rw-format, cdrecord, wodim, or cdrskin +can bring a DVD-RW out of overwriteable state so +that it has to be formatted again. If in doubt, just give it a try. +.SS +.B Drive preparation and addressing: +.br +The drives, CD, DVD, or BD burners, are accessed via addresses which +are specific to libburn and the operating system. Those addresses get listed +by a run of \fBcdrskin --devices\fP or \fBcdrskin --device_links\fP. +.br +On Linux, they are device files which traditionally do not offer +w-permissions for normal users. Because libburn needs rw-permission, +it might be only the +.B superuser +who is able to get this list without further +precautions. +.br +It is consensus that \fBchmod a+rw /dev/sr0\fP or \fBchmod a+rw /dev/hdc\fP +is less security sensitive than chmod u+s,a+x /usr/bin/cdrskin. The risk for +the drive is somewhat higher but the overall system is much less at stake. +Consider to restrict rw-access to a single group which bundles the users who +are allowed to use the burner drive (like group "floppy"). +.br +For drive permission examples on Linux, FreeBSD, and Solaris, +see cdrskin/README. +.br +.PP +If you only got one CD capable drive then you may leave out cdrskin option +\fBdev=\fP. Else you should use this option to address the drive you want. +.br +cdrskin option dev= not only accepts the listed addresses but also +traditional cdrecord SCSI addresses which consist of three numbers: +Bus,Target,Lun. On Linux there is also a related address family "ATA" which +accesses IDE drives not under control of Linux SCSI drivers: +ATA:Bus,Target,Lun. +.br +See option -scanbus for getting a list of cdrecord style addresses. +.br +Further are accepted: links to libburn-suitable device files, +device files which have the same major and minor device number, +and device files which have the same SCSI address parameters (e.g. /dev/sg0). +.br +.SS +.B Emulated drives: +.br +Option +.B --allow_emulated_drives +enables addressing of pseudo-drives +which get emulated on top of filesystem objects. Regular data files and +block devices result in pseudo-drives which behave much like DVD-RAM. +If the given address does not exist yet but its directory exists, then +it gets created as regular file. +Other file types like character devices or pipes result in pseudo-drives +which behave much like blank DVD-R. +The target file address is given after prefix "stdio:". +.br +E.g.: dev=stdio:/tmp/my_pseudo_drive +.br +Addresses of the form "stdio:/dev/fd/" are treated special. The +number is read literally and used as open file descriptor. With +dev="stdio:/dev/fd/1" the normal standard output of the program is +redirected to stderr and the stream data of a burn run will appear on stdout. +.br +Not good for terminals ! Redirect it. +.br +Pseudo-drives allow -dummy. Their reply with --tell_media_space can be utopic. +-dummy burn runs touch the file but do not modify its data content. +.br +Note: --allow_emulated_drives is restricted to stdio:/dev/null if cdrskin +is run by the +.B superuser +or if it has changed user identity via the +.B setuid +bit of its access permissions. The ban for the superuser can be lifted by a +skillfully created file. See section FILES below. +.br +.SH OPTIONS +.TP +.BI \-\-help +Show non-cdrecord compatible options. +.TP +.BI \-help +Show cdrecord compatible options. +.br +Note that some of the help texts are quite wrong - for cdrecord as well as +for cdrskin (e.g. -format, blank=, -load). They are, nevertheless, traditional +indicators for the availability of the listed options. Some frontend programs +make decisions after reading them. +.TP +.BI \-version +Print cdrskin id line, compatibility lure line, libburn version, cdrskin +version, version timestamp, build timestamp (if available), and then exit. +.PP +Alphabetical list of options which are intended to be compatible with +original cdrecord by Joerg Schilling: +.TP +.BI \-atip +Retrieve some info about media state. With CD-RW print "Is erasable". +With DVD media print "book type:" and a media type text. With BD media +print "Mounted Media:" and media type text. +.TP +.BI \-audio +Announces that the subsequent tracks are to be burned as audio. +The source is supposed to be uncompressed headerless PCM, 44100 Hz, 16 bit, +stereo. For little-endian byte order (which is usual on PCs) use option +-swab. Unless marked explicitly by option -data, input files with suffix +".wav" are examined wether they have a header in MS-WAVE format confirming +those parameters and eventually raw audio data get extracted and burned as +audio track. Same is done for suffix ".au" and SUN Audio. +.br +Option -audio may be used only with CD media and not with DVD or BD. +.TP +.BI blank= type +Blank a CD-RW, DVD-RW, or format a DVD-RW, DVD+RW, DVD-RAM, BD. +This is combinable with burning in the same run of cdrskin. +The type given with blank= selects the particular behavior: +.RS +.TP +as_needed +Try to make the media ready for writing from scratch. If it needs formatting, +then format it. If it is not blank, then try to apply blank=fast. +It is a reason to abort if the media cannot assume thoroughly writeable state, +e.g. if it is non-blank write-once. +.br +This leaves unformatted DVD-RW in unformatted blank state. To format DVD-RW use +blank=format_overwriteable. Blank unformatted BD-R stay unformatted. +.br +(Note: blank=as_needed is not an original cdrecord option.) +.TP +The following blank types are specific to particular media familes. Use them if special features are desired. +.TP +all +Blank an entire CD-RW or an unformatted DVD-RW. +(See also --prodvd_cli_compatible, --grow_overwriteable_iso) +.TP +fast +Minimally blank an entire CD-RW or blank an unformatted DVD-RW. +(See also --prodvd_cli_compatible, --grow_overwriteable_iso) +.TP +deformat_sequential +Like blank=all but with the additional ability to blank overwriteable DVD-RW. +This will destroy their formatting and make them sequentially recordable. +Another peculiarity is the ability to blank media which appear already blank. +This is similar to option -force but does not try to blank media other than +recognizable CD-RW and DVD-RW. +.br +(Note: blank=deformat_* are not original cdrecord options.) +.TP +deformat_sequential_quickest +Like blank=deformat_sequential but blanking DVD-RW only minimally. +This is faster than full blanking but may yield media incapable of +Incremental Streaming (-tao). +.TP +format_if_needed +Format a media if it is not formatted yet, +and if cdrskin supports formatting for the media type, +and if formatting will not happen automatically during write. +This currently applies to unformatted DVD-RW, DVD-RAM, BD-RE, +and blank unformatted BD-R. +Eventually the appropriate default formatting is chosen. +If other media or states are encountered then nothing happens. +.br +The following formatting types are more specialized to particular +media families. +.TP +format_overwrite +Format a DVD-RW to "Restricted Overwrite". The user should bring some patience. +.br +(Note: blank=format_* are not original cdrecord options.) +.TP +format_overwrite_quickest +Like format_overwrite without creating a 128 MiB trailblazer session. +Leads to "intermediate" state which only allows sequential write +beginning from address 0. +The "intermediate" state ends after the first session of writing data. +.TP +format_overwrite_full +For DVD-RW this is like format_overwrite but claims full media size +rather than just 128 MiB. +Most traditional formatting is attempted. No data get written. +Much patience is required. +.br +This option treats already formatted media even if not option -force is given. +.br +For DVD+RW this is the only supported explicit formatting type. It provides +complete "de-icing" so no reader slips on unwritten data areas. +.TP +format_defectmgt +Format DVD-RAM or BD to reserve the default amount of spare blocks for +defect management. +.br +The following format_defectmgt_* allow to submit user wishes which +nevertheless have to match one of the available formats. These formats are +offered by the drive after examining the media. +.TP +format_defectmgt_cert_off +Disable the usual media quality certification in order to save time and +format to default size. +The certification setting persists even if subsequent blank= options override +the size of the format selection. +.br +Whether formatting without certification works properly depends much on the +drive. One should check the "Format status:" from --list_formats afterwards. +.TP +format_defectmgt_cert_on +Re-enable the usual media quality certification and format to default size. +The certification setting persists like with format_defectmgt_cert_off. +.br +Whether there happens certification at all depends much on the media state +and the actually selected format descriptor. +.TP +format_defectmgt_max +Format DVD-RAM or BD to reserve a maximum number of spare blocks. +.TP +format_defectmgt_min +Format DVD-RAM or BD to reserve a minimum number of spare blocks. +It might be necessary to format format_defectmgt_none first in order to get +offered the most minmal spare blocks sizes for format_defectmgt_min. +.TP +format_defectmgt_none +Format DVD-RAM or BD-RE to the largest available payload in the hope to disable +defect management at all. This may or may not have a speed increasing effect. +Unformatted blank BD-R will be left unformatted. +.TP +format_defectmgt_payload_ +Format DVD-RAM or BD. The text after "format_defectmgt_payload_" gives a +number of bytes, eventually with suffixes "s", "k", "m". The largest number +of spare blocks will be chosen which allows at least the given payload size. +.TP +format_by_index_ +Format DVD-RW, DVD+RW, DVD-RAM or BD. +The number after "format_by_index_" is used as index to the list of available +format descriptors. This list can be obtained by option --list_formats. +The numbers after text "Format idx" are the ones to be used with +format_by_index_. Format descriptor lists are volatile. Do neither eject +nor write the media between the run of --list_formats and the run of +blank=format_by_index_ or else you may get a different format than desired. +.TP +help +Print this list of blanking types. +.RE +.TP +.BI \-checkdrive +Retrieve some info about the addressed drive and then exit. +Exits with non-zero value if the drive cannot be found and opened. +.TP +.BI \-dao +Alias for option -sao. Write CD in Session at Once mode +or DVD-R[W] in Disc-at-once mode. +.TP +.BI \-data +Subsequent tracks are data tracks. This option is default and only needed +to mark the end of the range of an eventual option -audio or -xa1. +.br +Options -mode2, -xa, and -xa2 get mapped to -data, not using the desired CD +sector formats and thus not taking advantage of eventual higher payload. +.BI \-xa1 +Subsequent tracks are data tracks with input suitable for CD-ROM XA mode 2 +form 1. This differs from -data input by 8 additional header bytes per block. +cdrskin will not write CD-ROM XA but rather strip the header bytes and write as +-data tracks. +.TP +.BI dev= target +Set the address of the drive to use. Valid are at least the +addresses listed with options --devices or --device_links, +X,Y,Z addresses listed with option -scanbus, +ATA:X,Y,Z addresses listed with options dev=ATA -scanbus, +and volatile libburn drive numbers (numbering starts at "0"). +Other device file addresses which lead to the same drive might work too. +.br +If no dev= is given, volatile address "dev=0" is assumed. That is the first +drive found being available. Better avoid this ambiguity on systems with more +than one drive. +.br +The special target "help" lists hints about available addressing formats. +Be aware that deprecated option --old_pseudo_scsi_adr may change the meaning +of Bus,Target,Lun addresses. +.TP +.BI driveropts= opt +Set "driveropts=noburnfree" to disable the drive's eventual protection +mechanism against temporary lack of source data (i.e. buffer underrun). +A drive that announces no such capabilities will not get them enabled anyway, +even if attempted explicitly via "driveropts=burnfree". +.TP +.BI \-dummy +Try to perform the drive operations without actually affecting the inserted +media. There is no warranty that this will work with a particular combination +of drive, media, and write mode. Blanking is prevented reliably, though. +To avoid inadverted real burning, -dummy refuses burn runs on anything but +CD-R[W], DVD-R[W], or emulated stdio-drives. +.TP +.BI \-eject +Eject the disc after work is done. +.TP +.BI \-force +Assume that the user knows better in situations when cdrskin or libburn are +insecure about drive or media state. This includes the attempt to blank +media which are classified as unknown or unsuitable, and the attempt to use +write modes which libburn believes they are not supported by the drive. +.br +Another application is to enforce blanking or re-formatting of media +which appear to be in the desired blank or format state already. +.br +This option enables a burn run with option -dummy even if libburn believes +that drive and media will not simulate the write mode but will write for real. +.br +It enables a burn run where cdrskin expects to exceed the available media +capacity. +.br +.B Caution: +Use this only when in urgent need. +.TP +.BI \-format +Same as blank=format_overwrite_full -force but restricted to DVD+RW. +.TP +.BI fs= size +Set the fifo size to the given value. The value may have appended letters which +multiply the preceding number: +.br +"k" or "K" = 1024 , "m" or "M" = 1024k , "g" or "G" = 1024m , "s" or "S" = 2048 +.br +Set size to 0 in order to disable the fifo (default is "4m"). +.br +The fifo buffers an eventual temporary surplus of track source data in order to +provide the drive with a steady stream during times of temporary lack of track +source supply. +The larger the fifo, the longer periods of poor source supply can be +compensated. +But a large fifo needs substantial time to fill up if not curbed via +option fifo_start_at=size. +.TP +.BI gracetime= seconds +Set the grace time before starting to write. (Default is 0) +.TP +.BI -immed +Equivalent to: +.br +modesty_on_drive=1:min_percent=75:max_percent=95 +.br +The name of this cdrecord option stems from the "Immed" bit which can make some +long running drive commands asynchronous and thus eases the load on some +wiring hardware types. Regardless of option -immed, cdrskin uses asynchronous +commands where possible and appropriate. +.TP +.BI -inq +Print the identification of the drive and then exit. +.TP +.BI -isosize +The next track following this option will try to obtain its source size from +the header information out of the first few blocks of the source data. +If these blocks indicate an ISO-9660 filesystem then its declared size +will be used under the assumption that it is a single session filesystem. +.br +If not, then the burn run will be aborted. +.br +The range of -isosize is exactly one track. Further tracks may be preceded +by further -isosize options, though. At least 15 blocks of padding will be +added to each -isosize track. But be advised to rather use padsize=300k. +.br +This option can be performed on track sources which are regular files or block +devices. For the first track of the session it can be performed on any type +of source if there is a fifo of at least 64 kiB. See option fs= . +.TP +.BI -load +Load the media and exit. Exit value is 0 if any kind of media was found, non +zero else. Note: Option -eject will unload the media even if -load is given. +.TP +.BI -lock +Like option -load but leave the drive's eject button disabled if there is any +media found and not option -eject is given. +.br +Use program "eject" or cdrskin -eject to get the tray out of the drive. +Runs of programs like cdrecord, growisofs, wodim, cdrskin will not be hampered +and normally enable the drive's eject button when they are done. +.TP +.BI minbuf= percentage +Equivalent to: +.br +modesty_on_drive=1:min_percent=:max_percent=95 +.br +Percentage is permissible between 25 and 95. +.TP +.BI -minfo +Print information about the loaded media. This includes media type, writability +state, and a quite readable table of content. +.TP +.BI msifile= path +Run option -msinfo and copy the result line into the file given by path. +Unlike -msinfo this option does not redirect all normal output away from +standard output. But it may be combined with -msinfo to achieve this. +.br +Note: msifile=path is actually an option of wodim and not of cdrecord. +.TP +.BI \-msinfo +Retrieve multi-session info for preparing a follow-up session by option -C +of programs mkisofs, genisoimage, or xorriso -as mkisofs. +Print result to standard output. +This option redirects to stderr all message output except the one of option +--tell_media_space and its own result string, which consists of two numbers. +The result string shall be used as argument of option -C with said programs. +It gives the start address of the most recent session and the predicted +start address of the next session to be appended. The string is empty if +the most recent session was not written with option -multi. +.br +To have a chance for working on overwriteable media, this option has to be +accompanied by option --grow_overwriteable_iso. +.TP +.BI \-multi +This option keeps CD, unformatted DVD-R[W], DVD+R, or BD-R appendable +after the current session has been written. +Without it the disc gets closed and may not be written any more - unless it +is a -RW and gets blanked which causes loss of its content. +.br +The following sessions can only be written in -tao mode. -multi is prohibited +with DVD-R[W] DAO write mode and on DVD-R DL media. +Option --prodvd_cli_compatible eventually makes +-multi tolerable but cannot make it work. +.br +In order to have all filesystem content accessible, the eventual ISO-9660 +filesystem of a follow-up +session needs to be prepared in a special way by the filesystem formatter +program. mkisofs and genisoimage expect particular info about the situation +which can be retrieved by cdrskin option -msinfo. +.br +To retrieve an archive file which was written as follow-up session, +you may use option -toc to learn about the "lba" of the desired track number. +This lba is the address of the 2048 byte block where the archive begins. +.br +With overwriteable DVD or BD media, -multi cannot mark the end of the session. +So when adding a new session this end has to be determined from the payload. +Currently only ISO-9660 filesystems can be used that way. See option +.B \--grow_overwriteable_iso +for lifting the ban on -multi. +.br +Note: -multi might make DVD media unreadable in some DVD-ROM drives. +.TP +.BI \-nopad +Do not add trailing zeros to the data stream. Nevertheless, since there seems +to be no use for audio tracks with incomplete last sector, this option applies +only to data tracks. There it is default. +.TP +.BI \-pad +Add 30 kiB of trailing zeros to each data track. (This is not sufficient to +avoid problems with various CD-ROM read drivers.) +.TP +.BI padsize= size +Add the given amount of trailing zeros to the next data track. This option +gets reset to padsize=0 after that next track is written. It may be set +again before the next track argument. About size specifiers, see option fs=. +.TP +.BI \-sao +Write CD in Session At Once mode or sequential DVD-R[W] in Disc-at-once +(DAO) mode. +.br +With CD this mode is able to put several audio tracks on media without +producing audible gaps between them. +.br +With DVD-R[W] this mode can only write a single track. +No -multi is allowed with DVD-R[W] -sao. +.br +-sao is permissible with overwriteable DVD, or DVD+R[/DL], or BD but actually +only imposes restrictions without providing known advantages. +.br +-sao can only be used for tracks of fixely predicted size. This implies that +track arguments which depict stdin or named pipes need to be preceded by +option tsize= or by option tao_to_sao_tsize=. +.br +-sao cannot be used on appendable media. +.TP +.BI \-scanbus +Scan the system for drives. On Linux the drives at /dev/s* and at /dev/hd* +are to be scanned by two separate runs. One without dev= for /dev/s* and +one with dev=ATA for /dev/hd* devices. (Option --drives lists all available +drives in a single run.) +.br +Drives which are busy or which offer no rw-permission to the user of cdrskin +are not listed. Busy drives get reported in form of warning messages. +.br +The useful fields in a result line are: +.br +Bus,Target,Lun Number) 'Vendor' 'Mode' 'Revision' +.TP +.BI speed= number +Set speed of drive. With data CD, 1x speed corresponds to a throughput of +150,000 bytes/second. With DVD, 1x = 1,385,000 bytes/second. +With BD 1x = 4,495,625 bytes/second. +It is not an error to set a speed higher than is suitable for drive +and media. One should stay within a realistic speed range, though. +Special speed settings are: +.br +0 = minimal speed , -1 = maximal speed (default), text "any" = like -1. +.TP +.BI \-swab +Announce that the raw audio data source of subsequent tracks is byte swapped +versus the expectations of cdrecord. This option is suitable for audio where +the least significant byte of a 16 bit word is first (little-endian, Intel). +Most raw audio data on PC systems are available in this byte order. +Less guesswork is needed if track sources are in format MS-WAVE in a file with +suffix ".wav". +.TP +.BI \-tao +Write CD in Track At Once (TAO) mode, sequential DVD-R[W] in Incremental +Streaming mode, or DVD+R[/DL] without traditional -sao restrictions. +This mode also applies pro-forma to overwriteable media +.br +Mode -tao can be used with track sources of unpredictable size, like standard +input or named pipes. It is also the only mode that can be used for writing +to appendable media which already hold data. With unformatted DVD-R[W] it is +the only mode which allows -multi. +.br +Mode -tao is not usable for minimally blanked DVD-RW and for DVD-R DL. +.TP +.BI \-toc +Print the table of content (TOC) which describes the tracks recorded on disc. +The output contains all info from option -atip plus lines which begin with +"track:", the track number, the word "lba:" and a number which gives the +start address of the track. Addresses are counted in CD sectors which with +SAO or TAO data tracks hold 2048 bytes each. +.RS +.TP +Example. Retrieve an afio archive from track number 2: +.br +tracknumber=2 +.br +lba=$(cdrskin dev=/dev/cdrom -toc 2>&1 | \\ +.br +grep '^track:[ ]*[ 0-9][0-9]' | \\ +.br +tail +"$tracknumber" | head -1 | \\ +.br +awk '{ print $4}' ) +.br +dd if=/dev/cdrom bs=2048 skip="$lba" | \\ +.br +afio -t - | less +.RE +.TP +.BI tsize= size +Announces the exact size of the next track source. This is necessary with any +write mode other than -tao if the track source is not a regular disk file, but +e.g. "-" (standard input) or a named pipe. +About size specifiers, see option fs=. +.br +If the track source does not deliver the predicted amount of bytes, the +remainder of the track is padded with zeros. This is not considered an error. +If on the other hand the track source delivers more than the announced bytes +then the track on media gets truncated to the predicted size and cdrskin exits +with non-zero value. +.TP +.BI \-v +Increment verbose level by one. Startlevel is 0 with only few messages. +Level 1 prints progress report with long running operations and also causes +some extra lines to be put out with info retrieval options. +Level 2 additionally reports about option settings derived from arguments or +startup files. Level 3 is for debugging and useful mainly in conjunction with +somebody who had a look into the program sourcecode. +.TP +.BI \-V +Enable logging of SCSI commands to stderr. This allows expert examination +of the interaction between libburn and the drive. The commands are specified +in SCSI-3 standards SPC, SBC, MMC. +.TP +.BI \-waiti +Wait until input data is available at stdin or EOF occurs at stdin. +Only then begin to access any drives. +.br +One should use this if cdrskin is working at the end of a pipe where the +feeder process reads from the drive before it starts writing its output into +cdrskin. Example: +.br +mkisofs ... -C 0,12800 -M /dev/sr0 | \\ +.br +cdrskin dev=/dev/sr0 ... -waiti - +.br +This option works even if stdin is not among the track sources. If no process +is piping in, then the Enter key of your terminal will act as trigger for +cdrskin. Note that this input line will not be consumed by cdrskin if stdin +is not among the track sources. It will end up as shell command, usually. +.PP +Alphabetical list of options which are genuine to cdrskin and intended for +normal use: +.TP +.BI \--adjust_speed_to_drive +Curb explicitly given speed= values to the maximum which is announced by the +drive for the loaded media. By default, such an adjustment is only made with +pseudo-speeds 0 and -1 whereas speed settings > 0 are sent unchanged to the +drive which will then choose an appropriate speed on its own. +.TP +.BI \--allow_emulated_drives +Enable drive addresses of the form dev=stdio:. See above, paragraph +"Drive preparation and addressing". +.TP +.BI \--allow_setuid +Disable the loud warning about insecure discrepance between login user and +effective user which indicates application of chmod u+s to the program binary. +One should not do this chmod u+s , but it is an old cdrecord tradition. +.TP +.BI \--any_track +Allow source_addresses to begin with "-" (plus further characters) or to +contain a "=" character. +By default such arguments are seen as misspelled options. It is nevertheless +not possible to use one of the options listed with --list_ignored_options. +.TP +.BI assert_write_lba= block_number | byte_address +Abort if the write address given with this option is not the same as predicted +immediately before the write session starts. This option can ensure that a +start address which was presumed by a formatter like mkisofs -C is really used +by the drive for writing. +assert_write_lba=0 effectively demands blank media and excludes appendables. +.br +Block numbering is peculiar: If the last character of the option string is +a letter [a-zA-Z] then the usual unit scaling by "s", "k", "m", etc. applies +and the result is divided by 2048. Else the number value of the string is +taken as plain block number with block size 2048 byte. +(E.g ...=1000 or ...=1000s means block 1000, ...=1m means block +512, ...=4096b means block number 2) +.TP +.BI \--demand_a_drive +Exit with a nonzero value if no drive can be found during a bus scan. +.TP +.BI \--devices +List the device file addresses of all accessible CD drives. In order to get +listed, a drive has to offer rw-permission for the cdrskin user and it may +not be busy. The superuser should be able to see all idle drives listed and +busy drives reported as "SORRY" messages. +.br +Each available drive gets listed by a line containing the following fields: +.br +Number dev='Devicefile' rw-Permissions : 'Vendor' 'Model' +.br +Number and Devicefile can both be used with option dev=, but number is +volatile (numbering changes if drives become busy). +.TP +.BI \--device_links +Like --devices, but presenting the drives with addresses of symbolic links +which point to the actual device files. +.br +Modern GNU/Linux systems may shuffle drive addresses from boot to boot. +The udev daemon is supposed to create links which always point to the +same drive, regardless of its system address. +Option --device_links shows the addresses of such links if they begin +by "/dev/dvd" or "/dev/cd". +Precedence is: "dvdrw", "cdrw", "dvd", "cdrom", "cd". +.TP +.BI direct_write_amount= size +Do not write a session with tracks but rather make an appropriate number of +direct write operations with no preparations. Flushing the drive buffer will +be the only finalization. It is advised to eject the media afterwards because +the write operations circumvent the usual system i/o with its caches and +buffers. By ejecting, those invalid memory copies get surely discarded. +.br +Only few media can be written this way: DVD-RAM, BD-RE, RVD+RW and +overwriteable DVD-RW. Writing is restricted to the already formatted +area of the media. +.br +Writing starts at byte 0 of the media or at the address given by option +.B write_start_address= . +Only the first track source is used as input for the write operations. +The fifo (fs=) is disabled. +.br +Parameter +.B size +controls the amount of data to be written. Size 0 means that the track source +shall be used up until EOF. In this case, the last write transaction gets +padded up to the necessary size by zeros. Size -1 revokes direct writing +and switches back to normal session oriented writing. +.br +Both, write_start_address and direct_write_amount size must be aligned to a +media dependend transaction size. With DVD-RAM, BD-RE, DVD+RW this is 2k, with +overwriteable DVD-RW it is 32k. +.TP +.BI dvd_obs= default|32k|64k +Linux specific: +Set the number of bytes to be transmitted with each write operation to DVD +or BD media. Tracks get padded up to the next multiple of this write +size. A number of 64 KB may improve throughput with bus systems which +show latency problems. The default depends on media type, option +stream_recording=, and on compile time options. +.TP +.BI fallback_program= command +Set a command name to be executed if cdrskin encounters a known cdrecord +option which it does not yet support. If a non-empty command is given with +fallback_program=, and if no essential options are given which are specific +to cdrskin, then cdrskin will delegate the job to said command. +.br +The natural commands to be given are cdrecord or wodim but one may well submit +the address of an own program. +.br +The fallback program will get all arguments of cdrskin which do not match +the shell patterns --?* or *_*=* . This eventually suppresses path names of +track sources which happen to match those patterns. The options from the +startup files are not handed to the fallback program. +.br +Fallback program execution is disabled if cdrskin is run setuid and not +option --allow_setuid is given. In general, the drive's device files and the +involved programs should be set up so that each program runs under its advised +conditions. (E.g. cdrskin as member of group floppy, cdrecord setuid root.) +.br +Two alias names for cdrskin are predefined with default fallback programs: +.br +.B unicord +implies fallback_program=cdrecord +.br +.B codim +implies fallback_program=wodim +.TP +.BI fifo_start_at= size +Do not wait for full fifo but start burning as soon as the given number +of bytes is read. This option may be helpful to bring the average throughput +near to the maximum throughput of a drive. A large fs= and a small +fifo_start_at= combine a quick burn start and a large savings buffer to +compensate for temporary lack of source data. At the beginning of burning, +the software protection against buffer underun is as weak as the size of +fifo_start_at= . So it is best if the drive offers hardware protection which +is enabled automatically if not driveropts=noburnfree is given. +.TP +.BI \--grow_overwriteable_iso +Enable emulation of multi-session writing on overwriteable media which +contain an ISO-9660 filesystem. This emulation is learned from growisofs -M +but adapted to the usage model of +.br +.B cdrskin -msinfo +.br +.B mkisofs -C -M | cdrskin -waiti [-multi] - +.br +--grow_overwriteable_iso does not hamper the use of true multi-session media. +I.e. it is possible to use the same cdrskin options with both kinds of media +and to achieve similar results if ISO-9660 filesystem images are to be written. +This option implies option -isosize and therefore demands that the track +source is a ISO-9660 filesystem image. +.br +With overwriteable media and no option blank=fast|all present it expands an +eventual ISO-9660 filesystem on media. It is assumed that this image's inner +size description points to the end of the valuable data. +Overwriteable media with a recognizable ISO-9660 size will be regarded as +appendable rather than as blank. I.e. options -msinfo and -toc will work. +-toc will always show a single session with its size increasing with +every added mkisofs image. +.br +If not overridden by option write_start_address=, the track with the new image +will be placed behind the end of the old one. One may use option +assert_write_lba= to make sure that media state and mkisofs job do match. +.br +--grow_overwriteable_iso causes option blank=fast|all to invalidate an +eventual ISO-9660 image by altering the first few bytes of block 16 on +overwriteable media. +Option -multi is tolerated in order not to hamper true multi-session media. +.br +An equivalent of growisofs -Z for overwriteable media is: +.br +.B mkisofs | cdrskin --grow_overwriteable_iso blank=fast [-multi] - +.br +With multi-session DVD, blank=fast will act like dvd+rw-format -blank=full . +.br +growisofs -dvd-compat is roughly equivalent to cdrskin without option -multi. +.TP +.BI \--list_formats +List the available format descriptors as reported by the drive for the +loaded media. Each descriptor line begins with "Format idx" and the +descriptor's list index, followed by a ":", the format type, the number +of payload blocks and that same number converted to MiB. +.br +The meaning of the format types is defined by the MMC standard +with command FORMAT UNIT. A user will more be interested in the +sizes than in the types. +.TP +.BI \--list_ignored_options +List all ignored cdrecord options. The "-" options cannot be used as addresses +of track sources. No track source address may begin with a text equal to an +option which ends by "=". The list is ended by an empty line. +.TP +.BI \--long_toc +Like option -toc but marking each session start by a line "first: X last: Y" +and each session end by "track:lout ...". +.TP +.BI \--no_rc +Only if used as first command line argument this option prevents reading and +interpretation of eventual startup files. See section FILES below. +.TP +.BI \--prodvd_cli_compatible +Activates behavior modifications with some DVD situations which bring cdrskin +nearer to the behavior of cdrecord-ProDVD: +.br +Option -multi with unsuitable media is not an error but simply has no effect. +.br +Options blank=fast and blank=all deformat overwriteable DVD-RW media. +.br +Option blank=fast does indeed minmal blanking with DVD-RW. This may yield media +which can only do DAO but not Incremental Streaming. +.TP +.BI \--single_track +Accept only the last argument of the command line as track source address. +.TP +.BI stdio_sync= on|off|number +Set the number of bytes after which to force output to drives with prefix +"stdio:". This forcing keeps the memory from being clogged with lots of +pending data for slow devices. Default "on" is the same as "16m". +Forced output can be disabled by "off". +.TP +.BI stream_recording= on|off|number +By setting "on" request that compliance to the desired speed setting is +preferred over management of write errors. With DVD-RAM and BD this can +bring effective write speed near to the nominal write speed of the media. +But it will also disable the automatic use of replacement blocks +if write errors occur. It might as well be disliked or ignored by the drive. +.br +If a number is given, then error management stays enabled for all byte +addresses below that number. Any number below 16s is the same as "off". +.TP +.BI tao_to_sao_tsize= size +Set an exact fixed size for the next track to be in effect only if the track +source cannot deliver a size prediction and no tsize= was specified and an +exact track size prediction is demanded by the write mode. +.br +This was the fallback from bad old times when cdrskin was unable to burn +in mode -tao . It came back with minimally blanked DVD-RW which allow no +Incremental Streaming (-tao) resp. with explicitly selected write mode -sao +for best DVD-ROM compatibility. +.br +If the track source delivers less bytes than announced then the missing ones +will be filled with zeros. +.TP +.BI --tell_media_space +Prepare a recording session, do not perform it but rather inquire the +maximum number of 2048 byte data blocks which may be written in +the current state of media with the prepared setup. So this option disables +recording of data. It does allow blanking, though, and will measure space +afterwards. +.br +It is not mandatory to give track sources but their nature may influence +the available capacity. So for most realistic results one may set up +the full burn session and add --tell_media_space. But if one has to expect +a cdrskin version prior to 0.3.3 no track source should be given in order +not to start an involuntary burn session. +In this case set at least -sao or -tao explicitly. +.br +The result gets printed to standard output. It is 0 or empty if no writing +is possible with the given options. +This option redirects to stderr all message output except its own result +string and eventual output of -msinfo. +.TP +.BI write_start_address= byte_offset +Set the address on media where to start writing the track. With DVD+RW, DVD-RAM +or BD-RE byte_offset must be aligned to 2 kiB blocks, but better is 32 kiB. +With DVD-RW 32 kiB alignment is mandatory. +.br +Other media are not suitable for this option yet. +.PP +Alphabetical list of options which are only intended for very special +situations and not for normal use: +.TP +.BI \--abort_handler +Establish default signal handling not to leave a drive in busy state +but rather to shut it down and to wait until it has ended the final operations. +This option is only needed for revoking eventual --ignore_signals or +--no_abort_handler. +.TP +.BI \--allow_untested_media +Enable the use of media profiles which have been implemented but not yet +tested. Currently this option is without effect because no media types are +under test reservation. +.br +(If you really test experimental media, then please report the outcome on +libburn-hackers@pykix.org) +.TP +.BI dev_translation= +Set drive address alias. This was necessary before cdrskin-0.2.4 to manually +translate cdrecord addresses into cdrskin addresses. +.br + is a single character which may not occur in the address string +. is an address as expected to be given by the user via option +dev=. is the address to be used instead whenever is given. +More than one translation instruction can be given in one cdrskin run. +.br +E.g.: dev_translation=+ATA:1,0,0+/dev/sr1 dev_translation=+ATA:1,1,0+/dev/sr2 +.TP +.BI \--drive_abort_on_busy +Linux specific: Abort process if a busy drive is encountered. +.TP +.BI \--drive_blocking +Linux specific: Try to wait for a busy drive to become free. +This is not guaranteed to work with all drivers. Some need nonblocking i/o. +.TP +.BI \--drive_f_setlk +Linux specific: Try to get exclusive lock on drive device file via fcntl(2). +.TP +.BI \--drive_not_exclusive +Linux specific: Combine --drive_not_f_setlk and --drive_not_o_excl. +.TP +.BI \--drive_not_f_setlk +Linux specific: Do not try to get exclusive lock on drive device file via +fcntl(2). +.TP +.BI \--drive_not_o_excl +Linux specific: Do not ask the operating system to prevent opening busy drives. +Wether this leads to senseful behavior depends on operating system and kernel. +.TP +.BI drive_scsi_dev_family= sr | scd | sg +Linux specific: Select a SCSI device file family to be scanned for by +options --devices, --device_links and -scanbus. +Normally this is /dev/sgN on kernel versions < 2.6 and /dev/srN +on kernels >= 2.6 . This option allows to explicitly override that default +in order to meet other programs at a common device file for each drive. +On kernel 2.4 families sr and scd will find no drives. +.br +Device file family /dev/hdX on kernel >= 2.6 is not affected by this setting. +.TP +.BI \--drive_scsi_exclusive +Linux specific: +Try to exclusively reserve device files /dev/srN, /dev/scdM, /dev/sgK of drives. +This would be helpful to protect against collisions with program growisofs. +Regrettably on Linux kernel 2.4 with ide-scsi emulation this seems not to +work. Wether it becomes helpful with new Linux systems has to be evaluated. +.TP +.BI \--fifo_disable +Disable fifo despite any fs=. +.TP +.BI \--fifo_per_track +Use a separate fifo for each track. +.TP +.BI \--fill_up_media +Expand the last track of the session to occupy all remaining free space on +the media. +.br +This option overrides option -multi. It will not fill up media if option -sao +is given with CD media. +.br +.B Caution: +With multi-session media this option might increase readatibility on DVD-ROM +drives but with some DVD recorders and media types it might also fail to +produce readable media at all. "Your mileage may vary". +.br +You can expect the best possible read compatibility if you do not use -multi at +all. +.TP +.BI grab_drive_and_wait= seconds +Open the addressed drive, wait the given number of seconds, release the drive, +and do normal work as indicated by the other options used. This option helps +to explore the program behavior when faced with busy drives. Just start a +second cdrskin with option --devices while grab_drive_and_wait= is still +active. +.TP +.BI \--ignore_signals +Try to ignore any signals rather than to abort the program. This is not a +very good idea. You might end up waiting a very long time for cdrskin +to finish. +.TP +.BI modesty_on_drive= [:min_percent=][:max_percent=] +Mode 1 keeps the program from trying to write to the burner drive while its +buffer is in danger to be filled by more than max_percent. If this filling is +exceeded then the program will wait until the filling is at most min_percent. +.br +This can ease the load on operating system and drive controller and thus help +with achieving better input bandwidth if disk and burner are not on independent +controllers (like hda and hdb). Unsufficient input bandwidth is indicated by +output "(fifo xy%)" of option -v if xy is lower than 90 for some time. +modesty_on_drive= might hamper output bandwidth and cause buffer underruns. +.br +To have max_percent larger than the burner's best actual +buffer fill has the same effect as min_percent==max_percent. Some burners +do not use their full buffer with all media types. Watch output "[buf xy%]" +of option -v to get an impression of the actual buffer usage. Some burners +are not suitable because they report buffer fill with granularity too large +in size or time. +.br +Mode 0 disables this feature. Mode -1 keeps it unchanged. Default is: +.br +modesty_on_drive=0:min_percent=65:max_percent=95 +.br +Percentages are permissible in the range of 25 to 100. +.TP +.BI \--no_abort_handler +On signals exit even if the drive is in busy state. This is not a very good +idea. You might end up with a stuck drive that refuses to hand out the media. +.TP +.BI \--no_blank_appendable +Refuse to blank appendable CD-RW or DVD-RW. This is a feature that was once +builtin with libburn. No information available for what use case it was needed. +.TP +.BI \--no_convert_fs_adr +Do only literal translations of dev=. This prevents cdrskin from test-opening +device files in order to find one that matches the given dev= specifier. +.br +Partly Linux specific: +Such opening is needed for Bus,Target,Lun addresses unless option +--old_pseudo_scsi_adr is given. It is also needed to resolve device file +addresses which are not listed with cdrskin --devices but nevertheless point +to a usable drive. (Like /dev/sg0 using the same SCSI address as /dev/sr0.) +.TP +.BI \--old_pseudo_scsi_adr +Linux specific: +Use and report literal Bus,Target,Lun addresses rather than real SCSI and +pseudo ATA addresses. This method is outdated and was never compatible with +original cdrecord. +.BI --xa1-ignore +Silently interpret option -xa1 as -data. This may be necessary if a frontent +does not prepare -xa1 block headers but insists in using option -xa1. +.SH EXAMPLES +.SS +.B Get an overview of drives and their addresses: +.br +cdrskin -scanbus +.br +cdrskin dev=ATA -scanbus +.br +cdrskin --device_links +.SS +.B Get info about a particular drive or loaded media: +.br +cdrskin dev=0,1,0 -checkdrive +.br +cdrskin dev=ATA:1,0,0 -v -atip +.br +cdrskin dev=/dev/hdc -minfo +.SS +.B Prepare CD-RW or DVD-RW for re-use, DVD-RAM or BD-RE for first use: +.br +cdrskin -v dev=/dev/sg1 blank=as_needed -eject +.SS +.B Format DVD-RW to avoid need for blanking before re-use: +.br +cdrskin -v dev=/dev/sr0 blank=format_overwrite +.SS +.B De-format DVD-RW to make it capable of multi-session again: +.br +cdrskin -v dev=/dev/sr0 blank=deformat_sequential +.SS +.B Write ISO-9660 filesystem image as only one to blank or formatted media: +.br +cdrskin -v dev=/dev/hdc speed=12 fs=8m \\ +.br +blank=as_needed -eject padsize=300k my_image.iso +.SS +.B Write compressed afio archive on-the-fly (not possible with minimally blanked DVD-RW or DVD-R DL): +.br +find . | afio -oZ - | \\ +.br +cdrskin -v dev=0,1,0 fs=32m speed=8 \\ +.br +blank=as_needed padsize=300k - +.SS +.B Write multi-session to the same CD, DVD-R[W], DVD+R[/DL], or BD-R: +.br +cdrskin dev=/dev/sr0 -v padsize=300k -multi 1.iso +.br +cdrskin dev=/dev/sr0 -v padsize=300k -multi 2.iso +.br +cdrskin dev=/dev/sr0 -v padsize=300k -multi 3.iso +.br +cdrskin dev=/dev/sr0 -v padsize=300k 4.iso +.SS +.B Get multi-session info for option -C of program mkisofs: +.br +c_values=$(cdrskin dev=/dev/hdc -msinfo 2>/dev/null) +.br +mkisofs ... -C "$c_values" ... +.SS +.B Inquire free space on media for a -multi run: +.br +x=$(cdrskin dev=/dev/sr0 -multi \\ +.br +--tell_media_space 2>/dev/null) +.br +echo "Available: $x blocks of 2048 data bytes" +.SS +.B Write audio tracks to CD: +.br +cdrskin -v dev=ATA:1,0,0 speed=48 -sao \\ +.br +track1.wav track2.au -audio -swab track3.raw +.br +.SH FILES +.SS +Startup files: +.br +If not --no_rc is given as the first argument then cdrskin attempts on +startup to read the arguments from the following files: +.PP +.br +.B /etc/default/cdrskin +.br +.B /etc/opt/cdrskin/rc +.br +.B /etc/cdrskin/cdrskin.conf +.br +.B $HOME/.cdrskinrc +.br +.PP +The files are read in the sequence given above, but none of them is +required for cdrskin to function properly.

Limited cdrecord compatibility wrapper for libburn

+
+ +

+

Purpose:

+Burns preformatted data to CD, DVD, and BD media:
+CD-R, DVD-R, DVD-R DL, DVD+R, DVD+R DL, BD-R, CD-RW, +DVD-RW, DVD-RAM, DVD+RW, BD-RE +

+

+ +

+ +Direct hop to download links -> + +

+

Hardware requirements:

+About any CD, DVD, or BD recorder produced in the recent ten years. +
+libburn +supports recorders which are compliant to standards MMC-1 for CD and +MMC-5 for DVD or BD. Linux, FreeBSD, and Solaris allow to access drives +connected via SCSI, PATA (aka IDE, ATA), USB, or SATA. +
+

+ +

+

Software requirements :

+
+
Linux with kernel 2.4 or higher (and libc, of course) :
+
With kernel 2.4 an ATA drive has to be under ide-scsi emulation.
+
With kernel 2.6 the drive should not be under ide-scsi.
+
or FreeBSD (with libc, of course) :
+
ATA and SATA drives need atapicam running.
+
libcam has to be installed.
+
or Solaris (with libc, of course) :
+
Tested on kernel 5.11, hopefully suitable for older ones too.
+
libpthread
+
is supposed to be a standard system component.
+
+

+ +

+

+GPL software included:
+

+
+
libburn-1.1.4
+
(founded by Derek Foreman and Ben Jansens, +developed and maintained since August 2006 by +Thomas Schmitt from team of libburnia-project.org) +
+
transfers data to CD, DVD, BD
+
+

+ +

+This program system has been tested on Intel/AMD with Linux, FreeBSD, +and OpenSolaris based operating systems.
+Ports to other usable systems are appreciated. Reports are welcome. +

+ +
+ +

+

Special features:

+
    +
  • Source code is independent of +cdrecord +
    • +
+

+ +

+

Commands:

+
+
The most common options of cdrecord for data and audio on CD media +are provided in a compatible way.
+On all DVD media, cdrskin is able to perform any recording job +which is possible with cdrecord. +Other than with cdrecord, option -multi is supported with many DVD types and +BD-R. Write mode -tao works with anything but quickly blanked DVD-RW and +DVD-R DL, which both support no -multi. +
+

+
Get an overview of drives and their addresses
+
# cdrskin -scanbus
+
# cdrskin dev=ATA -scanbus
+
# cdrskin --devices
+
Being superuser avoids permission problems with /dev/srN resp. /dev/hdX . +
+
Ordinary users should then get granted access to the /dev files +as listed by option --devices. Linux and FreeBSD demand rw-permission. +On Solaris it is r-permission and privileges "basic,sys_devices".
+
 
+ +
Get info about a particular drive or loaded media:
+
$ cdrskin dev=0,1,0 -checkdrive
+
$ cdrskin dev=ATA:1,0,0 -v -atip
+
$ cdrskin dev=/dev/hdc -minfo
+ +
Prepare CD-RW or DVD-RW for re-use, DVD-RAM or BD-RE for first use:
+
$ cdrskin -v dev=/dev/sg1 blank=as_needed -eject
+ +
Format DVD-RW to avoid need for blanking before re-use:
+
$ cdrskin -v dev=/dev/sr0 blank=format_overwrite
+ +
De-format DVD-RW to make it capable of multi-session again:
+
$ cdrskin -v dev=/dev/sr0 blank=deformat_sequential
+ +
Write ISO-9660 filesystem image as only one to blank or formatted media: +
+
$ cdrskin -v dev=/dev/hdc speed=12 fs=8m \
+
  blank=as_needed -eject padsize=300k my_image.iso
+ +
Write compressed afio archive on-the-fly +(not DVD-R DL or minimally blanked DVD-RW):
+
$ find . | afio -oZ - | \
+
  cdrskin -v dev=0,1,0 fs=32m speed=8 \
+
  blank=as_needed padsize=300k -
+ +
Write several sessions to the same CD, DVD-R[W] or DVD+R[/DL]:
+
$ cdrskin dev=/dev/hdc -v padsize=300k -multi 1.iso +
+
$ cdrskin dev=/dev/hdc -v padsize=300k -multi 2.iso +
+
$ cdrskin dev=/dev/hdc -v padsize=300k -multi 3.iso +
+
$ cdrskin dev=/dev/hdc -v padsize=300k 4.iso
+ +
Get multi-session info for option -C of program mkisofs:
+
$ c_values=$(cdrskin dev=/dev/sr0 -msinfo 2>/dev/null)
+
$ mkisofs ... -C "$c_values" ...
+ +
Inquire free space on media for a -multi run:
+
$ x=$(cdrskin dev=/dev/sr0 -multi \
+
  --tell_media_space 2>/dev/null)
+
$ echo "Available: $x blocks of 2048 data bytes"
+ +
Accelerate BD-RE writing to full nominal speed after the first 250 MB
+
$ cdrskin ... stream_recording=250m ... + +
Write audio tracks to CD:
+
$ cdrskin -v dev=ATA:1,0,0 speed=48 -sao \
+
  track1.wav track2.au -audio -swab track3.raw
+ +
Get overview of the cdrecord compatible options:
+
$ cdrskin -help
+ +
Get overview of the non-cdrecord options:
+
$ cdrskin --help
+ +
Read the detailed manual page:
+
$ man cdrskin
+
+
+
Read about the standard for which cdrskin is striving:
+
$  + +man cdrecord

+cdrskin-0.1.3.0.2.ts.tar.gz +
+Very special thanks to Andy Polyakov whose +dvd+rw-tools +provide libburn with invaluable examples on how to deal with DVD and BD media. +

+ +
+ + +

+

+
Example for a setup of device permissions.
+
+Newer Linux distros enable rw-access for the desktop user automatically. +So try as normal user whether all your drives are found. +CD devices which offer no rw-permission will stay invisible. +
+
$ cdrskin --devices
+
If not all desired drives show up, become superuser and do again:
+ +
# cdrskin --devices
+
...
+
0  dev='/dev/sr0'  rwr-r- :  'TEAC' 'CD-ROM CD-532S'
+
1  dev='/dev/hdc'  rwrw-- :  'LITE-ON' 'LTR-48125S'
+
Most simple and most insecure is this equivalent +of the usual cdrecord permissions u+s,a+x:
+
# chmod a+rw /dev/sr0 /dev/hdc
+
+More secure is to put the permitted users into a group like +"floppy", to assign /dev/sr0 /dev/hdc to this group, +and to allow rw-access only to group members. +
+
# vi /etc/group
+
...
+
floppy:x:19:thomas,scdbackup
+
...
+
# chgrp floppy /dev/sr0 /dev/hdc
+
# chmod g+rw /dev/sr0 /dev/hdc
+

About the relationship of cdrecord and cdrskin

+First of all: this relationship is single sided, as cdrskin has to be aware of +cdrecord but not vice versa. +
+
+I was a long time user of cdrecord and it worked fine for me. +Especially i do appreciate its write mode -tao which allows to pipe arbitrary +data on CD and CD-RW via stdin. cdrecord is reliable, versatile and well +maintained. So for me - there would be no problem with using it for +burning CDs. +
+But the author of cdrecord and the Linux kernel people foster a very hostile +relationship. Ok, that's their business, not mine (or ours if you are with me). +One has to be aware, though, that this relationship might lead to a situation +where cdrecord is no longer available for certain Linux kernels. +
+To have my own project prepared for such a time, i began to implement its +cdrecord gestures on top of libburn. +From now on i invite other interested users of cdrecord to teach cdrskin +the gestures necessary for their cdrecord applications. +Contact me. Let's see what we can achieve. +
+
+libburn and cdrskin are now mature enough to substitute cdrecord in its +major use cases of CD and DVD burning. It is possible to foist cdrskin on +various software packages if it gets falsely named "cdrecord". +I do not encourage this approach, but of course such a replacement +opportunity is the goal of a cdrecord compatibility wrapper. +
+
+It is very important to me that this project is not perceived as hostile +towards Joerg Schilling and his ongoing work. +I owe him much. For cdrecord, for mkisofs, for star. Chapeau. +

+'''cdrskin is the cdrecord compatibility middleware of libburn.''' + +Its paragon, cdrecord, is a powerful GPL'ed burn program included in Joerg +Schilling's cdrtools. cdrskin strives to be a second source for the services +traditionally provided by cdrecord. Currently it does CD-R and CD-RW this way. +Overwriteable media DVD-RAM, DVD+RW, DVD-RW, and BD-RE are handled differently +than with cdrecord-ProDVD in order to offer TAO-like single track recording. +Sequential DVD-R[W], DVD+R, DVD+R DL, BD-R are handled like CD-R[W] with TAO +and multi-session. Additionally cdrskin offers cdrecord-ProDVD-like mode DAO +with DVD-R[W]. + +cdrskin does not contain any bytes copied from cdrecord's sources. +Many bytes have been copied from the message output of cdrecord +runs, though. The most comprehensive technical overview of cdrskin +can be found in [http://libburnia-project.org/browser/libburn/trunk/cdrskin/README?format=txt cdrskin/README]. + +About libburn API for burning CD and DVD: http://api.libburnia-project.org + +-------------------------------------------------------------------------- + +For yet unsupported media types see the advice to use dvd+rw-tools at +the end of this text. + +-------------------------------------------------------------------------- + +About the command line options of cdrskin: + +They are described in detail in [http://scdbackup.sourceforge.net/man_1_cdrskin_devel.html#OPTIONS section OPTIONS] of +[http://scdbackup.sourceforge.net/man_1_cdrskin_devel.html man cdrskin] + +There are two families of options: cdrecord-compatible ones and options +which are specific to cdrskin. The latter are mostly used to configure +cdrskin for its task to emulate cdrecord. There are some, nevertheless, +which provide rather exotic unique features of cdrskin. + +The cdrecord-compatible options are listed in the output of +{{{ +cdrskin -help +}}} +where the option "help" has *one* dash. Online: [http://scdbackup.sourceforge.net/cdrskin_help_devel cdrskin -help] + +For these options you may expect program behavior that is roughly the +same as described in original man cdrecord . + +Online: http://cdrecord.berlios.de/old/private/man/cdrecord-2.0.html + +The cdrskin-specific options are listed by +{{{ +cdrskin --help +}}} +where the option "help" has *two* dashes. Online: [http://scdbackup.sourceforge.net/cdrskin__help_devel cdrskin --help] + +Some are very experimental and should only be +used in coordination with the libburnia developer team. +Some are of general user interest, though: + +-------------------------------------------------------------------------- + +--devices allows the sysadmin to scan the system for possible drives +and displays their detected properties. +The drives are listed one per line, with fields: +libburn-drive-number, sysadmin-device-file, permissions, vendor, type +{{{ +0 dev='/dev/sr0' rwrw-- : 'HL-DT-ST' 'DVDRAM GSA-4082B' +}}} +This feature is valuable since cdrskin -scanbus will not give you +the device file name and its current permissions. +cdrskin will accept of course the proposed dev= option as address +for any usage of the drive. + +Different from cdrecord, cdrskin is intended to be run without special +privileges, i.e. no superuser setuid. It is intended that the sysadmin +controls drive accessability by rw-permissions of the drive rather than +by x-permission of the burn binary. To be usable with cdrskin, the drive +has to offer both, r- and w-permission. + +-------------------------------------------------------------------------- + +blank=as_needed applies the suitable blanking or formatting to make +any supported type of media ready for writing from scratch. +If this is not possible, e.g. because the media is written and not +re-usable, then the program run fails. + +Option blank= offers several specialized blanking and formatting types, +which one may use for particular purposes on DVD-RW, DVD-RAM and BD-RE. +(See also below: blank=format_overwrite) +The drive offers a list of possible formats by cdrskin option --list_formats. +One should aquire MMC background information before making use of them. + +-------------------------------------------------------------------------- + +cdrskin does not only read from and write to optical drives which comply +to the MMC standard but also does the same with regular files or block +devices other than optical drives. + +Because the power to alter a disk file might be a bad surprise for a +traditional user of cdrecord, it is necessary to give option +--allow_emulated_drives before an emulated drive may be addressed. +Eventually one of the startup files would be a good place for it. +See man page, section FILES. + +The addresses of emulated drives begin with the prefix "stdio:". +{{{ +dev=stdio:/tmp/pseudo_drive +dev=stdio:/dev/usbstick +}}} + +Regular files and block devices behave much like DVD-RAM. + +Other file types may be valid targets for write-only operations. +This includes standard output, named pipes, character devices +{{{ +dev=stdio:/dev/fd/1 +dev=stdio:/tmp/named_pipe +dev=stdio:/dev/ptyxy +}}} + +These files behave much like blank DVD-R. + +All files used as pseudo-drives have to offer rw-permission. + + +-------------------------------------------------------------------------- + +The DVD capabilities of cdrskin differ from those of cdrecord-ProDVD. cdrskin +offers TAO-like multi-session with DVD-R[W], DVD+R[ DL] and TAO-like single +session with overwriteable DVD media. It also offers DAO on DVD-R[W] which is +probably the same as the traditional cdrecord-ProDVD write mode. + +Non-cdrecord blank mode blank=format_overwrite brings a DVD-RW +disc from its initial profile "Sequential Recording" into profile state +"Restricted Overwrite". +{{{ +cdrskin dev=/dev/sr0 -v blank=format_overwrite +}}} + +DVD-RAM, DVD+RW, BD-RE and overwriteable DVD-RW appear to cdrskin as blank +media which are capable of taking only a single track. This track may be +positioned on a 32KiB aligned address, though. +{{{ +cdrskin ... write_start_address=2412m ... +}}} + +Non-cdrecord blank mode blank=deformat_sequential brings an overwriteable +DVD-RW back into state "Sequential Recording" with the capability of doing +multi-session, if the drive is capable of "Incremental Streaming" +(MMC feature 21h). + +Used sequential DVD-RW media may be blanked by blank=fast or blank=all which +normally both do full blanking. Thus sequential DVD-RW behave much like large +CD-RW with possibly more than 99 tracks. + +blank=deformat_sequential does minimal blanking of DVD-RW which usually yields +media incapable of "Incremental Streaming". + +Option --prodvd_cli_compatible activates blank=fast and blank=all for +overwriteable DVD-RW which normally ignore those two options. It also makes +option -multi tolerable with media and write modes which are not suitable for +multi-session. (The default behavior of cdrskin deems me to be preferrable.) + +Option --grow_overwriteable_iso gives cdrskin ISO pseudo-multi-session +capabilities on DVD-RAM, DVD+RW, BD-RE similar to growisofs. +Associated options blank=, -multi, -msinfo and -toc are available in this case. +They either pretend a blank media (if there is no ISO 9660 image) or appendable +media with a single session and track on it. blank= invalidates ISO images. + + +-------------------------------------------------------------------------- + +assert_write_lba=<lba> allows to ensure that the start block address which +was used with the formatter program (e.g. mkisofs -C) matches the start block +address which will be used by the upcoming burn. + +E.g. cdrskin aborts with an error message if +{{{ +assert_write_lba=0 +}}} +is given but an appendable media is to be burned which would start at +block 68432. + + +An ISO-9660 file system image must be prepared according to a particular +block address on media. If the prepared address and the real address on media +do not match then the filesystem will not be mountable or may even cause system +trouble. + +A sequential archive format like afio or star will not necessarily need such +a coordination of addresses. It might nevertheless be confusing to a reader +if the archive does not start at block 0. + +-------------------------------------------------------------------------- + +fifo_start_at=<num> is a throughput enhancer for unsteady data streams +like they are produced by a compressing archiver program when piping to +CD on-the-fly. It makes better use of the general property of a FIFO +buffer to transport surplus bandwidth into the future. Yep. A time machine. +One-way, i fear. + +FIFO originally was introduced by cdrecord's author Joerg Schilling in order +to protect mediocre burner hardware from suffering buffer underruns +and thus producing misburns (at 1x speed on CD-R media at the price of a +DVD-RAM nowadays). This purpose would not justify a fifo any more - +given the limited life time of burners and the seamless underrun protection +of contemporary consumer drives. + +With an unsteady data stream the task of the buffer is to soak up peak +performance and to release it steadily at the drive's maximum speed. +The larger the buffer the more reserves can be built up and the longer +input drought can be compensated. + +Original cdrecord has the historical property, though, to first wait until +the buffer is completely filled. Best practice for fighting drive +underruns, of course. +With a very fat fs=# buffer (128 MB for 12x CD is not unrealistic) this +can cause a big delay until burning finally starts and takes its due time. + +fifo_start_at=<num> makes cdrskin start burning after the given number of bytes +is read rather than waiting for the FIFO to be completely full resp. the data +stream to end. It risks a few drive buffer underruns at the beginning of burn +- but modern drives stand this. + +Usage examples: +{{{ +cdrskin ... fs=128m fifo_start_at=20m ... +cdrskin ... fifo_start_at=0 ... +}}} + +Note: no FIFO can give you better average throughput than the average +throughput of the data source and the throughput of the burner. +It can be used, though, to bring the effective throughput very close +to the theoretical limit. Especially with high speed media. + +-------------------------------------------------------------------------- + +--no_rc allows you to surely ban influence from systemwide or user specific +default settings of cdrskin. Possible locations for such settings: + +/etc/default/cdrskin + +/etc/opt/cdrskin/rc + +/etc/cdrskin/cdrskin.conf + +$HOME/.cdrskinrc + +-------------------------------------------------------------------------- + +dev_translation=<sep><from><sep><to> may be needed to foist cdrskin to +frontend programs of cdrecord which do *not* ask cdrecord -scanbus but +which make own assumptions and guesses about cdrecord's device addresses. + +Normally, cdrskin understands all addresses which are suitable for cdrecord +under Linux. See cdrskin/README, "Pseudo-SCSI Adresses". +This option is mainly for (yet unknown) exotic configurations or very +stubborn frontend programs. + +If a frontend refuses to work with cdrskin, look into the error protocol +of that frontend, look at the output of a run of cdrskin --devices and give +cdrskin the necessary hint. +Example: Your frontend insists in using "0,0,0" and --devices reported +dev='/dev/hdc' resp. cdrskin dev=ATA -scanbus reported "1,0,0" then this +would be the appropriate translation: +{{{ +dev_translation=+0,0,0+/dev/hdc +}}} +The "+" character is a separator to be choosen by you. +Currently i am not aware of the need to choose any other than "+" +unless you get playful with custom translations like +{{{ +dev_translation=-"cd+dvd"-1,0,0 +}}} +See http://scdbackup.sourceforge.net/k3b_on_cdrskin.html +for an illustrated example with K3b 0.10 . + +-------------------------------------------------------------------------- + +DVD advise: + +For burning of DVD/BD media other than DVD-RAM, DVD+RW, DVD+R, DVD+R DL, +DVD-RW, DVD-R, BD-RE, the cdrskin project currently advises to use +Andy Polyakov's dvd+rw-tools which despite their historic name are +capable of all the media above and more, including BD discs. + +http://fy.chalmers.se/~appro/linux/DVD+RW/tools + +They are not compatible or related to cdrecord resp. cdrecord-ProDVD +(now obsoleted by original source cdrtools cdrecord with identical +capabilities besides the license key). + + +-------------------------------------------------------------------------- + +Advanced multi-session use cases: + +A special feature of dvd+rw-tools is growing of ISO-9660 filesystems on +overwriteable media. This is not the same as multi-session writing of cdrskin +with CD media, but retrieves additional information from the existing ISO +image and finally manipulates the start sectors of this existing image. + +So, inspired by growisofs, cdrskin can offer DVD multi-session not only with +sequential DVD-R[W] and with DVD+R [DL], but also with DVD-RAM, DVD+RW, BD-RE +and even regular disk files or block devices other than CD/DVD writers. +This is enabled by option --grow_overwriteable_iso. + +The libburnia project provides an integrated ISO-9660 multi-session tool +named [wiki:Xorriso xorriso] which tries to go one step beyond +growisofs. It uses [wiki:Libburn libburn] , [wiki:Libisofs libisofs] +and [wiki:Libisoburn libisoburn]. + +See [http://scdbackup.sourceforge.net/man_1_xorriso.html man xorriso]. + +-------------------------------------------------------------------------- + diff --git a/libburn/branches/1.1.6/configure.ac b/libburn/branches/1.1.6/configure.ac new file mode 100644 index 00000000..4cca5389 --- /dev/null +++ b/libburn/branches/1.1.6/configure.ac @@ -0,0 +1,319 @@ +AC_INIT([libburn], [1.1.5], [http://libburnia-project.org]) +AC_PREREQ([2.50]) +dnl AC_CONFIG_HEADER([config.h]) + +AC_CANONICAL_HOST +AC_CANONICAL_TARGET + +LIBBURNIA_SET_FLAGS + +AM_INIT_AUTOMAKE([subdir-objects]) +AC_CONFIG_MACRO_DIR([./]) + +dnl Notes by ts A71207 - B10409 : +dnl +dnl Regrettably the meaning of the various version types was misunderstood +dnl before version 0.4.1. +dnl +dnl In the past MAJOR.MINOR.MICRO versions led to the following SONAME numbers: +dnl 0.2.2 = 2 , 0.2.3 = 3 , 0.2.6 = 6 +dnl 0.3.0 = 0 , 0.3.2 = 2 , 0.3.4 = 4 . 0.3.6 = 6 , 0.3.8 = 4 +dnl 0.4.0 = 0 (also released as SONAME 4) +dnl +dnl Meanwhile the following schemes are maintained in parallel: +dnl +dnl BURN_MAJOR_VERSION , BURN_MINOR_VERSION , BURN_MICRO_VERSION +dnl are three small non-negative integers which describe the evolution +dnl steps of the library. +dnl Older applications are able to use younger libraries over +dnl quite a long range of such steps.

This page is about its capability to handle optical media. +For now this means CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD+R/DL, DVD-RW, +DVD-R, DVD-R/DL, BD-R, BD-RE. + +Our scope is currently Linux 2.4 and 2.6, or FreeBSD, or Solaris . For ports +to other systems we would need : login on a development machine resp. +an OS ithat is installable on an AMD 64-bit PC, advise from a system person +about the equivalent of Linux sg or FreeBSD CAM, volunteers for testing of +realistic use cases. + +libburn is the library by which preformatted data get onto optical media. +Its code is independent of cdrecord. Its DVD capabilities are learned from +studying the code of dvd+rw-tools and MMC-5 specs. No code but only the pure +SCSI knowledge has been taken from dvd+rw-tools, though. + +cdrskin is a limited cdrecord compatibility wrapper for libburn. +cdrecord is a powerful GPL'ed burn program included in Joerg Schilling's +cdrtools. cdrskin strives to be a second source for the services traditionally +provided by cdrecord. Additionally it provides libburn's DVD/BD capabilities, +where only -sao is compatible with cdrecord. +cdrskin does not contain any bytes copied from cdrecord's sources. +Many bytes have been copied from the message output of cdrecord runs, though. +See cdrskin/README for more. + +The burn API example of libburn is named test/libburner.c .

This number is needed for mkisofs option +-M to connect to the existing image. The new image will refer to files in +the previously existing image. mkisofs option -M needs read access to the +CD or a blockwise copy of it on hard disk. +The number is gained by 43h READ TOC/PMA/ATIP. +(mmc5r03c.pdf 6.26) +Untested is Format 0001b which in table 478 promises quick access via +Start Address Of First Track In Last Session. +(mmc5r03c.pdf 6.26.2.5 table 478, 6.26.3.3.1) +libburn gets the number from its Table Of Content model which is obtained +by 43h READ TOC/PMA/ATIP, Format 0010b. See below. + +The second number is an exact prediction of the Logical Block Address of the +new track which will contain the newly generated ISO-9660 image. +Even without mkisofs option -M this second number is still needed to make the +inner block address pointers of the image match the Logical Block Addresses +on CD. For that one may inquire 52h READ TRACK INFORMATION with +Address/Number Type set to 01b and Logical Block Address/Track/Session +Number set to FFh.

Its content is +(CTL|ADR ,00h,00h,01h,00h,00h,00h,00h) +With the CTL|ADR for the first track: 41h for data, 01h for audio. + +The LBA for the first write is negative: -150. This corresponds to MSF address +00h:00h:00h. All addresses are to be given in MSF format. +The first information track on disc is preceded by a pause encoding of 2 sec: +(CTL|ADR,01h,00h, DATA FORM ,00h,00h,00h,00h) +with DATA FORM = 00h for audio and 10h for data.

The MSF address is then increased by the size +of the track (to be used with next track or with lead-out). + +A track must at least contain 300 payload blocks: 4 seconds of audio or +600 KiB of data. +(mmc5r03c.pdf 6.33.3.6) + +At the end of the session there is a lead-out entry +(CTL|ADR,AAh,01h,01h,00h,MIN,SEC,FRAME) +marking the end of the last track.

I.e the Transfer Length of the previous 2Ah WRITE has to be +added to the Logical Block Address for the next 2Ah WRITE. Only full blocks +can be written. +(mmc5r03c.pdf, 6.44) +Writing begins at LBA -150 which is to be transmitted as 4-byte, Big-endian, +two's-complement. E.g: -150 = FFh FFh FFh 6Ah. This is the natural form found +with about any 32-bit processor, so only the endianness has to be taken into +respect when converting a 32-bit integer into a LBA for command 2Ah WRITE. + + +At first the mandatory pause preceding the first track has to be written as +150 blocks of the matching sector size: 2048 for data, 2352 for audio. +By this, the LBA increases from -150 to 0. + +Next the tracks' payload is sent. For each track exactly the number of blocks +has to be transmitted as is announced in the Cue Sheet by the difference +of the track's own start address and the start address of the next entry in +the Cue Sheet. After each write the LBA for the next write has to be increased +by the number of blocks transmitted. Just like with TAO writing. + +There is no separator between the tracks of a pure mode SAO session. +(If the session was mixed mode, there would be extended Pre-gaps and Post-gaps +between data mode tracks and audio mode tracks.) +(libburn sends its own buffer to the drive at the end of each track but does +not sync the drive's chache.

(I.e. no 5Bh CLOSE TRACK SESSION.) + + +---------------------------------------------------------------------------- +What is known about mixed mode sessions : + +For now, SAO sessions with a mix of data and audio are not supported in +libburn. Here are the reasons why. + +Obviously the code of http://icculus.org/burn is incomplete in this aspect. +In mmc5r03c.pdf comparison of table 555 and 6.33.3.18 seems self-contradicting. +(The second Pre-gap in table 555 does not match any of the criteria of +6.33.3.18. Also, there is no Post-gap shown in table 555 although 6.33.3.19 +would prescribe some.) + +If a data track follows an audio track then the data track gets a preceding +extended Pre-gap: +(CTL|ADR, TNO ,01h,DATA FORM,00h, MIN , SEC , FRAME) +with TNO already the number of the data track. The MSF address is to be +increased by 3 seconds. The first second of the extended Pre-gap needs to be +written in the audio track's mode and the other 2 seconds are to be written +in the data track's mode. +(libburn compares DATA FORM rather than burn_track.mode . Wrong ?) +(libburn currently does only 2 seconds and the second part of Pre-gap. There is +an issue with burn_track.pregap1 about this. Seems libburn mistakes the pause +preceding track 1 for a part 2 of an extended Pre-gap.) + +If a data track is followed by an audio track then it gets a Post-gap of at +least two seconds. +No example of Post-gap is given for Cue Sheet. Maybe it is to be added to the +track, or maybe it gets an own Cue Sheet entry ... who knows ? +(libburn contains write code for pregap1, pregap2 and postgap. But only +pregap2 ever gets activated. Once hackingly for the first 2 second pause, once +incompletely for a change of DATA FORM.) + +Seems nobody ever tested this.

There is no way to increase payload capacity by format 01h. +(mmc5r03c.pdf 6.5.4.2.2.1) + +With BD-RE there are three format types : 00h, 30h and 31h. +00h offers the default size format. This may be the only fast formatting +mode that is offered by the drive. +Feature 0023h tells whether format 31h and certain 30h subtypes are available. +(mmc5r03c.pdf 5.3.13) +30h offers several sizes with defect management. Usually there are three +sizes given: #1: default size, #2: maximum spare area, #3: minimal spare. +One may demand any spare size between maximum and minimum. There may be quick +certification and full certification. See feature 0023h. +31h offers a single size and disables defect management. This has the side +effect to speed up writing to nominal speed. +(mmc5r03c.pdf 6.5.4.2.15, 6.24.3.3, Table 472) + +Only format sizes from the list of format descriptors are permissible +for DVD-RAM. The format list can be obtained by 23h READ FORMAT CAPACITIES. +It also includes a description of the current formatting state. +(mmc5r03c.pdf 6.24, 6.24.3.2, 6.24.3.3) + +Formatting is done by command 04h FORMAT UNIT. Its data payload consists +of a Format List Header and a Format Descriptor. It is advisable to set +the Immed bit and the FOV bit in header byte number 1. The descriptor should +be a copy of a descriptor from 23h READ FORMAT CAPACITIES. +(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3) +With nearly all formats Sub-type should be set to 0. But with BD-RE formats +30h and 31h the Sub-type selects the certification mode. +Usable with 30h seem 10b Full Certification and 11b Quick Certification. +Usable with 31h seem also 00b Quick Reformat and 01b No Certification. +(mmc5r03c.pdf 6.5.4.2.15.1) + +Other format types have their certification intensity controlled by +a pair of bits: CmpList and DCRT. +CmpList resides in CDB byte 1 as bit 3. DCRT resides in the payload byte 1 +as bit 5.

See above. +There is no drive known yet which would apply command 2Ah WRITE10 to DVD-RAM +with full speed. + +The only known way to get full speed from DVD-RAM or BD-RE with enabled defect +management is the use of AAh WRITE12 with Streaming Bit set to 1. +(mmc5r03c.pdf 6.45) +With some DVD-RAM drives this fails if a write buffer is not full 32 kB. +With the tested BD-RE one must write full 64 kB buffers, or else writing +might not get into effect at all. + +Although it seems not optimal, this is specified not only to disable the +cumbersome checkread but also to ignore known defects and to write data +to these defective addresses. +(mmc5r03c.pdf 4.8.5) +So the speed-up is only advisable as long as the media are free of +incorrectable errors. + +Caveat: +MMC-5 does not guarantee AAh WRITE12 to work on DVD-RAM or BD-RE at all. +None of the features of profiles 0012h and 0043h promises the existence of +AAh WRITE12. +(mmc5r03c.pdf 5.4.13, 6.45) +Nevertheless it worked on all tested drives if proper alignment and block +size was observed. + + +------------------------------------------------------------------------------- +ISO 9660 multi-session emulation on overwriteable media : + +Overwriteable media provide a single overwriteable track which may grow up to +the full media capacity. There is no builtin table-of-content which records +the history of write sessions. +mount -t iso9660 will use sbsector=0 as default. +The term "superblock" shall depict the first 64 KiB after the sbsector address. + +ISO 9660 multi-session depends on typical TOC information in two ways: +It needs the superblock address MSC1 of the most recently recorded session and +it needs the Next Writeable Address NWA for which to prepare the adress offset. + +The following is learned from growisofs and from ECMA-119: +http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-119.pdf + +ISO 9660 filesystems provide information about the number of sectors which +is also the lowest unused block address and thus a suitable NWA. +This block address is stored in the Primary Volume Descriptor which is supposed +to be stored in block 16 (eventually relative to MSC1). +The bytes 0 to 5 of a PVD block are + 0x01 'C' 'D' '0' '0' '1' +The sector count can then be read from byte 80 to 83 + sectors= pvd[80] | (pvd[81] << 8) | (pvd[82] << 16) | (pvd[83] << 24); +(Ecma-119.pdf 8.4) +To support CD, DVD and BD media alike, it is advisable to round the NWA +to the next multiple of 32 (= 64 KiB). + +So one can use 0 as MSC1 and prepare a new ISO session for the computed NWA. +After writing the session it is necessary to patch the PVD at LBA 16. +The minimal change would be to update the number of image sectors. +It is stored in both notations LSB and MSB: + for(i= 0; i < 4; i++) + pvd[87 - i]= pvd[80 + i]= (sectors >> (8 * i)) & 0xff; + +cdrskin --grow_overwriteable_iso not only patches the sector fields of the +PVD block but also the blocks up to LBA 31 which begin with + 0xff 'C' 'D' '0' '0' '1' +libisoburn submits 64 KiB data buffer to libisofs before image generation and +afterwards writes these 64 KiB as new superblock to LBA 0. + + +------------------------------------------------------------------------------- +ISO 9660 based TOC emulation on overwriteable media : + +Above method of multi-session emulation yields a single session image after +each add-on session. No reliable session history can be read because the +sector size of the existing session gets overwritten by the new one. +A TOC with session history is nevertheless desirable with incremental backups +in order to access older backup states by mounting older superblocks at the +start addresses of older sessions. + +All usual ISO 9660 formatter programs write a complete superblock to the +start of each session. +With a uniform NWA rounding rule it is possible to compute the address of +superblock N+1 as the NWA after session N. The only problem is N=1 +because it gets overwritten by later sessions. + +libisoburn preserves the information of session 1 by writing the first session +to LBA 32 rather than LBA 0. Afterwards it writes the overall superblock to +LBA 0 (up to 31). +So with all further add-on sessions the superblock at LBA 0 will enclose the +overall image, while the superblocks of the sessions form a chain beginning +at LBA 32. Each session superblock points to the next one by its sector count +rounded up to 32. The chain end is marked by the overall image size. +This chain gives the start addresses of sessions. The sector count minus start +address gives the size of a particular session.

But not being backed by the specs this method appears unappealing . + +Another approach would be a formatted Table of Content, obtained by 43h READ +TOC/PMA/ATIP Format 0000b. The specs do not totally outrule that this returns +useful data with non-CD but they define a crippled TOC for multi-session. +(mmc5r03c.pdf 6.26.3.2.4) +My LG drive returns a more detailed TOC, my NEC drive stays with the rather +suboptimal specs. So one would get different TOCs on different drives. +Nevertheless, the MMC-5 compliant TOC would return the desired number in +the Track Start address of the track with the highest number before AAh. + +Most stable seems the approach to obtain the desired number from the reply +of 52h READ TRACK INFORMATION, Address/Number Type 01b. The field Logical Block +Address/Track/Session has to bear the track number of the first track in the +last complete session. To determine this number one has to determine the +number of the last session and the number of the last track from 51h READ DISC +INFORMATION and to iterate over the tracknumber by 52h READ TRACK INFORMATION +until the first track with the desired session number appears and reveils +its start address. +(mmc5r03c.pdf 6.22 51h DISC, 6.27 52h TRACK) +This method is very near to fabricating an own TOC. So libburn does this +when inspecting the media. If the first number for -C is needed, libburn +inquires its TOC model for the address of the first track in the last +complete session. See below for a detailed description of TOC fabrication. + + +The second -C number is the exact prediction of future track start address. It +is gained like with CD by 52h READ TRACK INFORMATION Type 01b. Different from +CD one may not use track number FFh but has to use the Last Track in Last +Session from 51h READ DISC INFORMATION. +(mmc5r03c.pdf 6.22 51h DISC, 6.27 52h TRACK) + + +------------------------------------------------------------------------------- +Obtaining a Table Of Content from DVD-R[W]: +(valid for DVD+R too) + +The raw TOC entries from 43h READ TOC/PMA/ATIP Format 0010b as described with +CD media are not available with non-CD. +There is a Format 0000b "Formatted TOC" but this is with non-CD a fictional +information much at the discretion of the drive. Two drives with the same disc +may well return different Formatted TOC. They are supposed to be consistent +only about the last complete session and even there the MMC-5 specification +6.26.3.2.5 seems to prescribe a structure which does not match the true +structure of incremental writing to sequential DVD-R[W]. +(mmc5r03c.pdf 6.26.3.2) +So i prefer not to use this method of getting a TOC. + + +The alternative is to produce an own TOC from information gained by 51h READ +DISC INFORMATION and by 52h READ TRACK INFORMATION which reveil a CD-like +structure of sessions and 1:n related tracks. + +51h READ DISC INFORMATION Data Type 000b, fields Number of Sessions (Least +Significant Byte) and Number of Sessions (Most Significant Byte) give the +number of sessions. The last complete session number of an appendable disc +is one less because there is an incomplete session at its end. libburn only +records complete sessions in its TOC model. +libburn uses Last Track in Last Session as a hint for the range of track +numbers. +(mmc5r03c.pdf 6.22) + +Next step is to iterate from 1 up to the last track number and to obtain +the according track info by 52h READ TRACK INFORMATION. Each track tells its +Session Number (LSB at byte 2, MSB at 33), its Logical Track Start Address, +its Logical Track Size, and much more which is not needed for a fake CD TOC. +One may analyze the track info more finely but for this special purpose +it is enough to discard the tracks which do not belong to complete sessions. +(mmc5r03c.pdf 6.27) + +At the end of each session libburn inserts fake leadout entries into its TOC +model.

A comment in +growisofs_mmc.cpp states: "// DVD-R DL Seq has no notion of multi-session". +I am not reading this from the specs - but not explicitely the contrary either. + +For now libburn will close the session but there is a macro prepared in +libburn/write.c Libburn_dvd_r_dl_multi_no_close_sessioN which will suppress +close session if multi-session is demanded. + + +------------------------------------------------------------------------------- + +------------------------------------------------------------------------------- + DVD+R[/DL] Cookbook +------------------------------------------------------------------------------- +Inspired by reading mmc5r03c.pdf from http://www.t10.org/ftp/t10/drafts/mmc5/ +backed by Andy Polyakov's http://fy.chalmers.se/~appro/linux/DVD+RW/tools , + +For libburnia-project.org by Thomas Schmitt <scdbackup@gmx.net> + +------------------------------------------------------------------------------- + +Media type can be recognized by Current Profile from 46h GET CONFIGURATION. +(mmc5r03c.pdf 6.6.2.1) +DVD+R 001bh +DVD+R/DL 002bh + +- About empty, appendable and finalized DVD+R +- Writing a Pseudo Session to DVD+R +- DVD+R/DL (Dual Layer + +The following two chapters of the Sequential DVD-R[W] Cookbook are valid for +DVD+R media too: +- Obtaining DVD-R[W] multi-session info for extending ISO-9660 filesystems +- Obtaining a Table Of Content from DVD-R[W] + +------------------------------------------------------------------------------- +About blank, appendable and finalized DVD+R : + +In the beginning a DVD+R holds an empty session and the Incomplete Fragment. +From these one may spawn reserved fragments or one may write directly to +the incomplete fragment.

Probably not, or else one could make NWAs run +into vLBAs which are associated with older rLBAs. + +Replacing invalidated blocks consumes addresses in rLBA space at the NWA of +some track.

E.g. those addresses which have neither been +written as rLBA nor as vLBA yet. So one should begin the vLBA of new sessions +at the NWA of a sufficiently sized track. +(mmc5r03c.pdf 4.5.3.5.4.2 , 4.5.3.6.9) + +------------------------------------------------------------------------------- + diff --git a/libburn/branches/1.1.6/doc/ddlp.txt b/libburn/branches/1.1.6/doc/ddlp.txt new file mode 100644 index 00000000..9211ea57 --- /dev/null +++ b/libburn/branches/1.1.6/doc/ddlp.txt @@ -0,0 +1,388 @@ +------------------------------------------------------------------------------- + +Users of modern desktop Linux installations report misburns with CD/DVD +recording due to concurrency problems. + +This text describes two locking protocols which have been developed by our +best possible effort.

So any good-willing program +has to take some extra precautions to participate. + +If a program does not feel vulnerable to disturbance, then the precautions +impose much less effort than if the program feels the need for protection. + +Two locking strategies are specified: +DDLP-A operates on device files only. It is very Linux specific. +DDLP-B adds proxy lock files, inspired by FHS /var/lock standard. + + + DDLP-A + +This protocol relies on the hardly documented feature open(O_EXCL | O_RDWR) +with Linux device files and on POSIX compliant fcntl(F_SETLK). + +Other than the original meaning of O_EXCL with creating regular files, the +effect on device files is mutual exclusion of access. I.e. if one +filedescriptor is open on that combination of major-minor device number, then +no other open(O_EXCL) will succeed. But open() without O_EXCL would succeed. +So this is advisory and exclusive locking. +With kernel 2.6 it seems to work on all device drivers which might get used +to access a CD/DVD drive. + +The vulnerable programs shall not start their operation before they occupied a +wide collection of drive representations. +Non-vulnerable programs shall take care to detect the occupation of _one_ such +representation. + + So for Friendly Programs + +A program which does not feel vulnerable to disturbance is urged to access +CD/DVD drives by opening a file descriptor which will uphold the lock +as long as it does not get closed. There are two alternative ways to achieve +this. +Very reliable is + + open( some_path , O_EXCL | ...) + +But O_EXCL imposes restrictions and interferences: +- O_EXCL | O_RDONLY does not succeed with /dev/sg* ! +- O_EXCL cannot provide shared locks for programs which only want to lock + against burn programs but not against their own peers. +- O_EXCL keeps from obtaining information by harmless activities. +- O_EXCL already has a meaning with devices which are mounted as filesystems. + This priority meaning is more liberal than the one needed for CD/DV recording + protection. + +So it may be necessary to use a cautious open() without O_EXCL and to aquire +a POSIX lock via fcntl(). "Cautious" means to add O_NDELAY to the flags of +open(), because this is declared to avoid side effects within open(). + +With this gesture it is important to use the paths expected by our burn +programs: /dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z] +because fcntl(F_SETLK) does not lock the device but only a device-inode. + + std_path = one of the standard device files: + /dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z] + or a symbolic link pointing to one of them. + open( std_path , ... | O_NDELAY) + fcntl(F_SETLK) and close() on failure + ... eventually disable O_NDELAY by fcntl(F_SETFL) ... + +There is a pitfall mentioned in man 2 fcntl : + "locks are automatically released [...] if it closes any file descriptor + referring to a file on which locks are held. This is bad [...]" +So you may have to re-lock after some temporary fd got closed. + + + Vulnerable Programs + +For programs which do feel vulnerable, O_EXCL would suffice for the /dev/hd* +device file family and their driver. But USB and SATA recorders appear with +at least two different major-minor combinations simultaneously. +One as /dev/sr* alias /dev/scd*, the other as /dev/sg*. +The same is true for ide-scsi or recorders attached to SCSI controllers. + +So, in order to lock any access to the recorder, one has to open(O_EXCL) +not only the device file that is intended for accessing the recorder but also +a device file of any other major-minor representation of the recorder. +This is done via the SCSI address parameter vector (Host,Channel,Id,Lun) +and a search on standard device file paths /dev/sr* /dev/scd* /dev/sg*. +In this text the alternative device representations are called "siblings". + +For finding them, it is necessary to apply open() to many device files which +might be occupied by delicate operations. On the other hand it is very +important to occupy all reasonable representations of the drive. +So the reading of the (Host,Channel,Id,Lun) parameters demands an +open(O_RDONLY | O_NDELAY) _without_ fcntl() in order to find the outmost +number of representations among the standard device files. Only ioctls +SCSI_IOCTL_GET_IDLUN and SCSI_IOCTL_GET_BUS_NUMBER are applied. +Hopefully this gesture is unable to cause harmful side effects on kernel 2.6. + +At least one file of each class sr, scd and sg should be found to regard +the occupation as satisfying. Thus corresponding sr-scd-sg triplets should have +matching ownerships and access permissions. +One will have to help the sysadmins to find those triplets. + +A spicy detail is that sr and scd may be distinct device files for the same +major-minor combination.

It can +be embedded into DDLP-A or it can be used be used standalone, outside DDLP-A. + +DDLP-A shall be kept by DDLP-B from trying to access any device file which +might already be in use. There is a problematic gesture in DDLP-A when SCSI +address parameters are to be retrieved. For now this gesture seems to be +harmless. But one never knows. +Vice versa DDLP-B may get from DDLP-A the service to search for SCSI device +file siblings. So they are best as a couple. + +But they are not perfect. Not even as couple. fcntl() locking is flawed. + + +There is a proxy file locking protocol described in FHS: + http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLOCKLOCKFILES + +But it has shortcommings (see below). Decisive obstacle for its usage are the +possibility for stale locks and the lack of shared locks. + +DDLP-B rather defines a "path prefix" which is advised to be + /tmp/ddlpb-lock- +This prefix will get appended "device specific suffixes" and then form the path +of a "lockfile". +Not the existence of a lockfile but its occupation by an fcntl(F_SETLK) will +constitute a lock. Lockfiles may get prepared by the sysadmin in directories +where normal users are not allowed to create new files. Their rw-permissions +then act as additional access restriction to the device files. +The use of fcntl(F_SETLK) will prevent any stale locks after the process ended. +It will also allow to obtain shared locks as well as exclusive locks. + +There are two classes of device specific suffixes: + +- Device file path suffix. Absolute paths only. "/" gets replaced by "_-". + Eventual "_-" in path gets replaced by "_-_-". The leading group of "_-" + is always interpreted as a group of "/", though. E.g.: + /dev/sr0 <-> "_-dev_-sr0" + /mydevs/burner/nec <-> "_-mydevs_-burners_-nec" + /dev/rare_-name <-> "_-dev_-rare_-_-name" + ///strange/dev/x <-> "_-_-_-strange_-dev_-x" + +- st_rdev suffix. A hex representation of struct stat.st_rdev. Capital letters. + The number of characters is pare with at most one leading 0. I.e. bytewise + printf("%2.2X") beginning with the highest order byte that is not zero. + E.g. : "0B01", "2200", "01000000000004001" + +If a lockfile does not exist and cannot be created then this shall not keep +a program from working on a device. But if a lockfile exists and if permissions +or locking state do not allow to obtain a lock of the appropirate type, then +this shall prevent any opening of device file in question resp. shall cause +immediate close(2) of an already opened device file. + +The vulnerable programs shall not start their operation before they locked a +wide collection of drive representations. + +Non-vulnerable programs shall take care to lock the suffix resulting from the +path they will be using and the suffix from the st_rdev from that path. +The latter is to be obtained by call stat(2). + +Locks get upheld as long as their file descriptor is not closed or no other +incident as described in man 2 fcntl releases the lock. + +So with shared locks there are no imandatory further activities after they +have been obtained. + +In case of exclusive locks, the file has to have been opened for writing and +must be truncated to 0 bytes length immediately after obtaining the lock. +When releasing an exclusive lock it is a nice gesture to +already do this truncation. +Then a /var/lock/ compatible first line has to be written. +E.g. by: printf("%10u\n",(unsigned) getpid()) yielding " 1230\n". + +Any further lines are optional. They shall have the form Name=Value and must +be printable cleartext. If such further lines exist, then the last one must +have the name "endmark". +Defined Names are: + hostid =hostname of the machine where the process number of line 1 is valid + start =start time of lock in seconds since 1970. E.g: 1177147634.592410 + program =self chosen name of the program which obtained the lock + argv0 =argv[0] of that program + mainpath =device file path which will be used for operations by that program + path =device file path which lead to the lock + st_rdev =st_rdev suffix which is associated with path + scsi_hcil=eventual SCSI parameters Host,Channel,Id,Lun + scsi_bus =eventual SCSI parameter Bus + endmark =declares the info as complete. +Any undefined name or a line without "=" shall be handled as comment. +"=" in the value is allowed. Any line beginning with an "=" character is an +extension of the previous value. + +If programs encounter an exclusive lock, they are invited to read the content +of the lockfile anyway. But they should be aware that the info might be in the +progress of emerging. There is a race condition possible in the short time +between obtaining the exclusive lock and erasing the file content. +If it is not crucial to obtain most accurate info then one may take the newline +of the first line as indicator of a valid process number and the "endmark" +name as indicator that the preceding lines are valid. +Very cautious readers should obtain the info twice with a decent waiting period +inbetween. Only if both results are identical they should be considered valid. + + +There is no implementation of DDLP-B yet. + + + +---------------------------------------------------------------------------- +What are the Stumble Stones ? +---------------------------------------------------------------------------- + +Any of the considered locking mechanisms has decisive shortcommings +which keeps it from being the solution to all known legitimate use cases. + +The attempt has failed to compose a waterproof locking mechanism from means of +POSIX, FHS and from hardly documented Linux open(O_EXCL) on device files. +The resulting mechanisms would need about 1000 lines of code and still do +not close all gaps resp. cover the well motivated use cases. +This attempt you see above: DDLP-A and DDLP-B. + + +Summary of the reasons why the established locking mechanisms do not suffice: + +None of the mechanisms can take care of the double device driver identity +sr versus sg. To deduce the one device file from the other involves the need +to open many other (possibly unrelated) device files with the risk to disturb +them. +This hard to solve problem is aggravated by the following facts. + +Shortcommings of Linux specific open(O_EXCL) : + +- O_EXCL | O_RDONLY does not succeed with /dev/sg* +- O_EXCL cannot provide shared locks for programs which only want to lock + against burn programs but not against their own peers. +- O_EXCL keeps from obtaining information by harmless activities. +- O_EXCL already has a meaning with devices which are mounted as filesystems. + This priority meaning is more liberal than the one needed for CD/DV recording + protection. + +Shortcommings of POSIX fcntl(F_SETLK) : + +- fcntl() demands an open file descriptor. open(2) might have side effects. +- fcntl() locks can be released inadvertedly by submodules which just open and + close the same file (inode ?) without refering to fcntl locks in any way. + See man 2 fcntl "This is bad:". + Stacking of software modules is a widely used design pattern. But fcntl() + cannot cope with that. + +Shortcommings of FHS /var/lock/ : + +- Stale locks are possible. +- It is necessary to create a file (using the _old_ meaning of O_EXCL flag ?) + but /var/lock/ might not be available early during system start and it often + has restrictive permission settings. +- There is no way to indicate a difference between exclusive and shared locks. +- The FHS prescription relies entirely on the basename of the device file path. + diff --git a/libburn/branches/1.1.6/doc/doxygen.conf.in b/libburn/branches/1.1.6/doc/doxygen.conf.in new file mode 100644 index 00000000..ab620751 --- /dev/null +++ b/libburn/branches/1.1.6/doc/doxygen.conf.in @@ -0,0 +1,1294 @@ +# Doxyfile 1.5.3 + +# This file describes the settings to be used by the documentation system +# doxygen (www.doxygen.org) for a project +# +# All text after a hash (#) is considered a comment and will be ignored +# The format is: +# TAG = value [value, ...] +# For lists items can also be appended using: +# TAG += value [value, ...] +# Values that contain spaces should be placed between quotes (" ") + +#--------------------------------------------------------------------------- +# Project related configuration options +#--------------------------------------------------------------------------- + +# This tag specifies the encoding used for all characters in the config file that +# follow.

Confusingly in the C code "^" is said exor. + Note: This is not C1, C2 which is rather mentioned in ECMA-130 Annex C and + always performed inside the drive. + ------------------------------------------------------------------------- + + + RSPC resp. P- and Q-Parity + + ECMA-130 Annex A prescribes to compute the parity bytes for P-columns and + Q-diagonals by RSPC based on a Galois Field GF(2^8) with enumerating + polynomials x^8+x^4+x^3+x^2+1 (i.e. 0x11d) and x^1 (i.e. 0x02). + Bytes 12 to 2075 of a audio-sized sector get ordered in two byte words + as 24 rows and 43 columns. Then this matrix is split into a LSB matrix + and a MSB matrix of the same layout. Parity bytes are to be computed + from these 8-bit values. + 2 P-bytes cover each column of 24 bytes. They get appended to the matrix + as rows 24 and 25. + 2 Q-bytes cover each the 26 diagonals of the extended matrix. + + Both parity byte pairs have to be computed so that extended rows or + diagonals match this linear equation: + H x V = (0,0) + H is a 2-row matrix of size n matching the length of the V ectors + [ 1 1 ... 1 1 ] + [ x^(n-1) x^(n-2) x^1 1 ] + Vp represents a P-row. It is a byte vector consisting of row bytes at + position 0 to 23 and the two parity bytes which shall be determined + at position 24 and 25. So Hp has 26 columns. + Vq represents a Q-diagonal. It is a byte vector consisting of diagonal + bytes at position 0 to 42 and the two parity bytes at position 43 and 44. + So Hq has 45 columns. The Q-diagonals cover P-parity bytes. + + By applying some high school algebra one gets the parity bytes b0, b1 of + vector V = (n_payload_bytes, b0 , b1) as + + b0 = ( H[n] * SUM(n_payload_bytes) - H[0..(n-1)] x n_payload_bytes ) + / (H[n+1] - H[n]) + b1 = - SUM(n_payload_bytes) - b0 + + H[i] is the i-the element of the second row of matrix H. E.g. H[0] = x^(n-1) + The result has to be computed by Galois field arithmetics. See below. + + The P-parity bytes of each column get reunited as LSB and MSB of two words. + word1 gets written to positions 1032 to 1074, word0 to 1075 to 1117. + The Q-parity bytes of each diagonal get reunited too. word1 goes to 1118 + to 1143, word0 to 1144 to 1169. + >>> I do not read this swap of word1 and word0 from ECMA-130 Annex A. + >>> But the new output matches the old output only if it is done that way. + >>> See correctness reservation below. + + Algebra on Galois fields is the same as on Rational Numbers. + But arithmetics is defined by operations on polynomials rather than the + usual integer arithmetics on binary numbers. + Addition and subtraction are identical with the binary exor operator. + Multiplication and division would demand polynomial division, e.g. by the + euclidian algorithm. The computing path over logarithms and powers follows + algebra and allows to reduce the arithmetic task to table lookups, additions + modulo 255, and exor operations. Note that the logarithms are natural + numbers, not polynomials. They get added or subtracted by the usual addition + (not by exor) and their polynomial power depends on their value modulo 255. + + Needed are a logarithm table and a power table (or inverse logarithm table) + for Galois Field GF(2^8) which will serve to perform the peculiar + multiplication and division operation of Galois fields. + + The power table is simply an enumeration of x^n accorting to + GF-multiplication. It also serves as second line of matrix H for the parity + equations: + Hp[i] = gfpow[25-i] , i out of {0,..,25} + Hq[i] = gfpow[44-i] , i out of {0,..,44} + + The logarithm table is the inverse permutation of the power table. + + Some simplifications apply to the implementation: + In the world of Galois fields there is no difference between - and +. + The term (H[n+1] - H[n]) is constant: 3. + + ------------------------------------------------------------------------- + + + Scrambling + + ECMA-130 Annex B prescribes to exor the byte stream of an audio-sized sector + with a sequence of pseudo random bytes. It mentions polynomial x^15+x+1 and + a 15-bit register. + It shows a diagram of a Feedback Shift Register with 16 bit boxes, though. + + Comparing this with explanations in + http://www.newwaveinstruments.com/resources/articles/m_sequence_linear_feedback_shift_register_lfsr.htm + one can recognize the diagram as a Fibonacci Implementation. But there seems + really to be one bit box too many. + + The difference of both lengths is expressed in function next_bit() by + the constants 0x3fff,0x4000 for 15 bit versus 0x7fff,0x8000 for 16 bits. + Comparing the output of both alternatives with the old scrambler output + lets 15 bit win for now. + + So the prescription is to start with 15 bit value 1, to use the lowest bit + as output, to shift the bits down by one, to exor the output bit with the + next lowest bit, and to put that exor result into bit 14 of the register. + + ------------------------------------------------------------------------- + + + Correctness Reservation + + In both cases, parity and scrambling, the goal for now is to replicate the + output of the dismissed old lec.c by output which is based on published + specs and own implementation code.

The data structure of +the class is described by some lines which get read from stdin. The stub will +consist of four files which emerge in the current working directory: + <classname>.h public header file of the class + <classname>.c automatically generated C code of the class + plus a copy of <classname>.c.methods + <classname>_private.h private header file of the class + <classname>.c.methods safe storage for manually created functions. + From here they get copied into the generated stub. + If such a file is missing, a dummy gets created. +It will define a struct <ClassnamE> for representing the class data aspects, +construtor <Classname>_new(), destructor <Classname>_destroy(), +getter <Classname>_<element>_get() for each structure element. +Some more functions get added for particular class and element roles. + +cgen normally refuses to overwrite existing files because it supposes that +those contain code added by the human programmer. +Human programmer enhancements may be explanatory comments, class specific +methods, initial element values and other special precautions within the +generated functions. +As long as the modelling phase is going on, one may store such human code +in <classname>.c.methods and may use command line option -overwrite for +modelling development cycles. + +At some point of model matureness one may decide to give up cgen and the +.c.method files and to go on only with _private.h , .h and .c files. + + +Command line options + + -no_stic prevents usage of stic_dir/s_tools/*.[ch] + + -ansi generates ANSI C function heads and makes file <classname>.h hold + only public definitions: an opaque declaration of the class struct + and a list of function prototypes. The definiton of the class + struct is then in <classname>_private.h . + -global_include filename + sets the name of a file which will contain globally necessary + declarations. Currently it lists the existence of all class + structs. + -lowercase generate struct <classname> rather than struct <ClassnamE> and + function names <classname>_func() rather than <Classname>_func() . + -overwrite allows to overwrite files <classname>_private.h, <classname>.h + and <classname>.c, but not <classname>.c.methods. + + +Input line format: + +There are two states of input: class level and element level. +Exampes are shown below with class roles and element roles. + +Input starts at class level. A class level line may be one of + +- Comment. A line which begins with '#' is ignored on class level. + +- Empty. A line with no characters is a comment with empty text (i.e. ignored). + +- Class. Options which begin with '-' and finally a word in lowercase letters + which defines the <classname>. The classname leads to a struct ClassnamE + and some class methods implemented as C functions <Classnname>_<func>(). + +- End of input. Line "@@@" or EOF at stdin end the program run. + +After a class line, input switches to element level where a line may be: + +- Comment. A line which after some white space begins with '#' is considered + a comment. The preceeding white space is ignored and the text after '#' is + eventuellay trimmed by a single blank at both ends. This text will be part + of the class struct definition within file <classname_private>.h as a single + C comment line /* ... */. The sequence of elements and comments is preserved. + An empty comment text leads to an empty line in <classname_private>.h. + +- Empty. A line with no characters is a comment with empty text. + +- Element. Options which begin with '-', eventual C keywords "unsigned" or + "volatile", type or "struct <NamE>", element name. This leads to a struct + element which is taken into respect in some class methods. Depending on the + options in this line, some element methods <Classnname>_<func>_<element>() + may get generated. + +- End of class. A single '@' marks the end of the element list and brings + input back to class level. I.e. next is expected another class name or + "@@@" or EOF at stdin. + +Input semantics: + +A class can have one of two roles: + +- Standalone class. + Input example: + my_class + +- Listable class, which has pointers to peer instances: .prev and .next + Such classes get a list destructor <Classname>_destroy_all() which destroys + all members of a list (which is given by any of the list members). + Such a class should have a pointer *boss as first element in which case + the constructor will look like + <Classname>_new(struct <ClassnamE> **o,struct <Some_clasS> *boss,int flag); + There is a function <Classname>_link() which inserts an instance into a list + and a function <Classname>_count() which tells the number of list members. + For pseudo random access there is function <Classname>_by_idx(). + Input example: + -l my_class + + +A modifier is defined for classes: + +- Bossless. Disables a special boss-subordinate relationship which is created + if the first element of a class is a struct pointer with the name "boss". + Like + -l <classname> + -v struct Some_clasS *boss + Normally such a parameter *boss becomes part of the constructor method + <Classname>_new(struct <ClassnamE> **o, struct Some_clasS *boss, int flag); + This relationship is typical for a listable class and a single class which + is designed to host instances of that listable class. Therefore one gets a + warning if a listable class does not begin with a struct pointer *boss. + But if -b is given, then CgeN ill not include a parameter *boss into the + constructor. It will rather look normal: + <Classname>_new(struct <ClassnamE> **o, int flag); + It will not warn if the first element of a listable class is not struct + pointer *boss. + + +Elements have one of the following roles: + +- Value. It provides only storage for a C data type (which may be a C pointer + despite the role name "value"), a getter method <Classname>_<element>_get(), + and a setter method <Classname>_<element>_set(). + Input examples: + -v int i + -v int a[100] + -v char *cpt + -v struct xyz x + -v struct xyz *xpt + +- Managed. This has to be a pointer to a struct <XyZ> or to char. It will not + get attached to an object by the stub's code but its destructor + <Xyz>_destroy() will be called by <Classname>_destruct(). In case of (char *) + it is supposed that a non-NULL value has been allocated by malloc(). + Managed (char *) types get a setter function <Classname>_<element>_set() + which allocates memory and copies the textstring from its parameter. + Input examples: + -m struct XyZ *xyzpt + -m char *textstring + +- Chainlink. A pair of prev-next-style pointers to the own class struct. + Function <Classname>_destruct() will unlink the affected instance and + put together its link partners. + Input example (there must always be two consequtive -c lines): + -c struct My_clasS *up + -c struct My_clasS *down + +- List. A pair of pointers to the struct <XyZ> of a listable class. The first + one <ls> holds the start of the list, the second one <eol> holds the end. + The getter function has an additional argument idx: + <Classname>_get_<ls>(struct <ClassnamE> *o, int idx, struct <XyZ> **pt, + int flag) + idx == 0 is the start of the list, idx=1 the next element, ... + idx == -1 retrieves the last element of the list. + For insertion of list items there is provided method <Classname>_new_<ls>(). + The inserted item is reachable via the getter function with idx == -1 + <Classname>_destroy() instance calls <Xyz>_destroy_all(). Note that the end + pointer is always generated as private element (-p). + Input example (there must always be a -l and a -v line): + -l struct XyZ *list_start + -v struct XyZ *list_end + +The availability of getter method <Classname>_get_<element>(), and setter +method <Classname>_set_<element>_set() can be controled by two modifiers: + +- Readonly. Only a getter method. + Input example + -r -v int broadcasted_status + +- Private. Neither getter nor setter method. + Input example + -p -v int private_value + +- Bossless listable.

is the early working name for the successor software of libburn, +# a library for writing information onto optical media, i.e. CD and DVD. +# The current working name is libcevap, refering to various kinds of roasts in +# Europe and Asia which share the property to be structured in smaller pieces. +# +# The reason for the replacement is the unclear copyright situation as well +# as libburn's sketchy original state and the subsequential evolutionary +# damages done by us in libburn code. +# This does not mean libburn is shaky. Its current state just reflects the +# virtual conflict of at least two programmer personalities and their goals. +# + +# +# Please: Nobody shall take the development of libcevap as a reason for not +# programming an application which uses libburn. +# libburn works now. libcevap is planned to work in future. +# +# libcevap will replace libburn in a controlled, application friendly way. +# The first application of libcevap will be a libburn API wrapper which will +# allow to perform all API calls of libburn which are proveable to work in +# the current implementation. (Some CD stuff is not understood by us yet. +# We will have to learn.) +# +# The libburn API will be frozen when libcevap has closed up to its current +# capabilities. Nevertheless it may take profit from some of the future +# progress in libcevap (e.g. new media types). +# We hope that finally libcevap will have capabilities superior to libburn. +# This will then be a reason to port applications to the libcevap API. +# +# Application programmers are advised to encapsulate their libburn API calls +# in an own abstraction layer. The semantic concepts of burning will be +# compatible between libburn and libcevap. I.e you will have a library object +# to be started up, drives to be found and grabbed, media and their states +# to be identified, sessions, tracks, burn options to be set, blanking, +# formatting, and so on. +# Data types, function calls, and quirks will be incompatible between both +# APIs, though. +# + +# ------------------------------------------------------------------------- + +# Originally this was a backup of text input clicketitoggled into ArgoUML +# Meanwhile it becomes an intermediate storage for attributes and +# class interconnections in the notation of my C stub generator CgeN +# (see also end of this text) + +# next : work on completeness : cevapformat + +# Open questions: +# - how to connect to GESTURES ?
