GNU GENERAL PUBLIC LICENSE - Version 2, June 1991 - - Copyright (C) 1989, 1991 Free Software Foundation, Inc. - 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. 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/COPYRIGHT b/COPYRIGHT deleted file mode 100644 index 7b7b4b7..0000000 --- a/COPYRIGHT +++ /dev/null @@ -1,18 +0,0 @@ -Derek Foreman and Ben Jansens -Copyright (C) 2002-2006 Derek Foreman and Ben Jansens -Mario Danic , Thomas Schmitt -Copyright (C) 2006-2008 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 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.

The following -more-detailed instructions are generic; see the `README' file for -instructions specific to this package. - - The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation. It uses -those values to create a `Makefile' in each directory of the package. -It may also create one or more `.h' files containing system-dependent -definitions. 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/Makefile.am b/Makefile.am deleted file mode 100644 index f1a4e42..0000000 --- a/Makefile.am +++ /dev/null @@ -1,202 +0,0 @@ -pkgconfigdir=$(libdir)/pkgconfig -libincludedir=$(includedir)/libburn - -lib_LTLIBRARIES = libburn/libburn.la - -## ========================================================================= ## - -# Build libraries -libburn_libburn_la_LDFLAGS = \ - -version-info $(LT_CURRENT):$(LT_REVISION):$(LT_AGE) -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/error.h \ - libburn/file.c \ - libburn/file.h \ - libburn/init.c \ - libburn/init.h \ - libburn/lec.c \ - libburn/lec.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 - -## ========================================================================= ## - -## Build test applications -noinst_PROGRAMS = \ - test/libburner \ - test/telltoc \ - test/dewav \ - test/fake_au \ - test/poll \ - test/structest - -bin_PROGRAMS = \ - cdrskin/cdrskin - -test_libburner_CPPFLAGS = -Ilibburn -test_libburner_LDADD = $(libburn_libburn_la_OBJECTS) $(THREAD_LIBS) -test_libburner_SOURCES = test/libburner.c -test_telltoc_CPPFLAGS = -Ilibburn -test_telltoc_LDADD = $(libburn_libburn_la_OBJECTS) $(THREAD_LIBS) -test_telltoc_SOURCES = test/telltoc.c -test_dewav_CPPFLAGS = -Ilibburn -test_dewav_LDADD = $(libburn_libburn_la_OBJECTS) $(THREAD_LIBS) -test_dewav_SOURCES = test/dewav.c -test_fake_au_CPPFLAGS = -test_fake_au_LDADD = -test_fake_au_SOURCES = test/fake_au.c -test_poll_CPPFLAGS = -Ilibburn -test_poll_LDADD = $(libburn_libburn_la_OBJECTS) $(THREAD_LIBS) -test_poll_SOURCES = test/poll.c -test_structest_CPPFLAGS = -Ilibburn -test_structest_LDADD = $(libburn_libburn_la_OBJECTS) $(THREAD_LIBS) -test_structest_SOURCES = test/structest.c - -## cdrskin construction site - ts A60816 - A80510 -cdrskin_cdrskin_CPPFLAGS = -Ilibburn -cdrskin_cdrskin_CFLAGS = -DCdrskin_libburn_0_4_6 - -# cdrskin_cdrskin_LDADD = $(libburn_libburn_la_OBJECTS) $(THREAD_LIBS) -# ts A80123, change proposed by Simon Huggins to cause dynamic libburn linking -cdrskin_cdrskin_LDADD = libburn/libburn.la $(THREAD_LIBS) - -cdrskin_cdrskin_SOURCES = cdrskin/cdrskin.c cdrskin/cdrfifo.c cdrskin/cdrfifo.h cdrskin/cdrskin_timestamp.h -## -## Open questions: how to compute $timestamp and express -DX="$timestamp" -## - - - -## ========================================================================= ## - -## Build documentation (You need Doxygen for this to work) -webhost = http://libburn-api.pykix.org -webpath = / -docdir = $(DESTDIR)$(prefix)/share/doc/$(PACKAGE)-$(VERSION) - -doc: doc/html - -doc/html: doc/doxygen.conf - if [ -f ./doc/doc.lock ]; then \ - $(RM) -r doc/html; \ - doxygen doc/doxygen.conf; \ - fi - -doc-upload: doc/html - scp -r $ and Thomas Schmitt -Copyright (C) 2006-2008 Mario Danic, Thomas Schmitt - -Still containing parts of -Libburn.

For preparing the build of a SVN -snapshot you will need autotools of at least version 1.7. -Check out from SVN by - svn co http://svn.libburnia-project.org/libburn/trunk libburn -go into directory libburn and apply autotools by - ./bootstrap - -Alternatively you may unpack a release tarball for which you do not need -autotools installed. - -To build a libburnia-project.org subproject it should be sufficient to go -into its toplevel directory (here: "libburn") and execute - ./configure --prefix=/usr - make - -To make the libraries accessible for running resp. developing applications -and to install the cdrecord compatibility binary cdrskin, do: - make install - - -An important part of the project, libisofs, is hosted in a bzr repository at -launchpad.net : - bzr branch lp:libisofs - -Another part the project, libisoburn, is hosted in the libburnia SVN, too: - svn co http://svn.libburnia-project.org/libisoburn/trunk libisoburn - -See README files there. - - ------------------------------------------------------------------------------- - - - Overview of libburnia-project.org - -libburnia-project.org is an open-source software project for reading, mastering -and writing optical discs. -For now this means only CD media and all single layer DVD media except DVD+R. - -The project comprises of several more or less interdependent parts which -together strive to be a usable foundation for application development. -These are libraries, language bindings, and middleware binaries which emulate -classical (and valuable) Linux tools. - -Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems -we would need : login on a development machine resp. a live OS on CD or DVD, -advise from a system person about the equivalent of Linux sg or FreeBSD CAM, -volunteers for testing of realistic use cases. - -We have a well tested code base for burning data and audio CDs and many DVD -types. The burn API is quite comprehensively documented and can be used to -build a presentable application. -We have a functional binary which emulates the core use cases of cdrecord in -order to prove that usability, and in order to allow you to explore libburn's -scope by help of existing cdrecord frontends. - -ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created -and manipulated quite freely. 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. - libisofs is to be the foundation of our upcoming mkisofs emulation. - -- 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. - -- 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 deletion, renaming, and attribute - changing. - See xorriso/README for more. - -- "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). - - ------------------------------------------------------------------------------- -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 contibutors 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. For the origin of this name, see - http://en.wikipedia.org/wiki/Liburnians . - -- 16th January 2007 release of libburn-0.3.0 and cdrskin-0.3.0 . 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. Code for double layer DVD+/-R is implemented but awaits a tester - yet. - -- 23th April 2007 version 0.3.6 follows the unanimous opinion of Linux kernel - people that one should not use /dev/sg on kernel 2.6. - -- 31st July 2007 version 0.3.8 marks the first anniversary of libburn revival. - We look back on improved stability, a substantially extended list of media - and write modes, and better protection against typical user mishaps. - -- 24th October 2007 version 0.4.0 is the foundation of new library libisoburn - and an upcomming integrated application for manipulating and writing - ISO 9660 + Rock Ridge images. cdrskin-0.4.0 got capabilities like growisofs - by these enhancements: growing of overwriteable media and disk files. - Taking again a bow towards Andy Polyakov. - -- 26th Januar 2008 version 0.4.2 rectifies the version numbering so that we - reliably release libburn.so.4 as should have been done since libburn-0.3.2. - cdrskin now is by default linked dynamically and does a runtime check - to ensure not to be started with a libburn which is older than itself. - -- 3rd Feb 2008 libisofs-0.2.x (.so.5) has been deprecated. - -- 14th Feb 2008 libisofs-0.6.2 permanently replaces the old libisofs-0.2.x. - It is the first release of new libisofs.so.6 which will guarantee future - API/ABI compatibility for its whole feature set. - -- 15th Feb 2008 libisoburn-0.1.0 (.so.1) coordinates libisofs and libburn for - the purpose of ISO image reading and writing. It emulates multi-session on - overwriteable media. Application xorriso makes use of all three libraries. - -- 8th Apr 2008 libburn-0.4.4 has proven to be capable of burning to DVD+R/DL - and read performance on disk file pseudo-drives has been improved. - -- 27th Apr 2008 libisofs-0.6.4 can now read data file content from images - and can map pieces of disk files onto image files. Image directory iteration - has been enhanced. Input data streams and extended information have been - exposed in the API to allow future development. - -- 29th Apr 2008 libisoburn-0.1.4 was made more efficient with reading of - image tree nodes. It now depends on libisofs-0.6.4 and libburn-0.4.4. - xorriso makes use of new libisofs features by performing incremental - updates of directory trees and by cutting oversized data files into - pieces. A primitive single session emulation of cdrcord and mkisofs is - provided. - -- 10th May 2008 libburn-0.4.6 supports formatting and writing of BD-RE, - full nominal speed for DVD-RAM and BD-RE. cdrskin has a unified blank - type with automatic media state recognition. - - ------------------------------------------------------------------------------- - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation.

(See -below for a way to create a statically linked binary.) - -To install the man page, you may do: echo $MANPATH and choose one of the -listed directories to copy the man-page under its ./man1 directory. Like: - cp cdrskin/cdrskin.1 /usr/share/man/man1/cdrskin.1 - -Note: The content of the cdrskin tarball is essentially the complete libburn - of the same version number. You may thus perform above steps in a local - SVN copy of libburn or in a unpacked libburn tarball as well. - - - Usage - -The user of cdrskin needs rw-permission for the CD burner device. -A list of rw-accessible drives can be obtained by - - cdrskin --devices - -CD devices which offer no rw-permission are invisible to normal users. -The superuser should be able to see any usable drive and then set the -permissions as needed. If this hangs then there is a drive with -unexpected problems (locked, busy, broken, whatever). You might have to -guess the address of your (non-broken) burner by other means, then. -On Linux 2.4 this would be some /dev/sgN and on 2.6. some /dev/srM or /dev/hdX. - -The output of cdrskin --devices might look like - - 0 dev='/dev/sr0' rwrwr- : '_NEC' 'DVD_RW ND-4570A' - 1 dev='/dev/sr1' rwrw-- : 'HL-DT-ST' 'DVDRAM GSA-4082B' - -So full and insecure enabling of both for everybody would look like - - chmod a+rw /dev/sr0 /dev/sr1 - -This is equivalent to the traditional setup chmod a+x,u+s cdrecord. - -I strongly discourage to run cdrskin with setuid root or via sudo ! -It is not checked for the necessary degree of hacker safety. - -Consider to put all authorized users into group "floppy", to chgrp the -device file to that group and to disallow w-access to others. - -Helpful with Linux kernel 2.4 is a special SCSI feature: -It is possible to address a scsi(-emulated) drive via associated device files -which are not listed by option --devices but point to the same SCSI addresses -as listed device files. This addressing via e.g. /dev/sr0 or /dev/scd1 is -compatible with generic read programs like dd and with write program growisofs. -For finding /dev/sg1 from /dev/sr0, the program needs rw-access to both files. - - - Usage examples - -For options and recordable media classes see - man 1 cdrskin - -Get an overview of cdrecord style addresses of available devices - cdrskin -scanbus - cdrskin dev=ATA -scanbus - cdrskin --devices - -Adresses reported with dev=ATA need prefix "ATA:".

For particular CD legacy commands, standards MMC-3 and MMC-1 apply. - -For the original meaning of cdrecord options see : - man cdrecord - (http://cdrecord.berlios.de/old/private/man/cdrecord-2.0.html) -Do not bother Joerg Schilling with any cdrskin problems. -(Be cursed if you install cdrskin as "cdrecord" without clearly forwarding - this "don't bother Joerg" demand.) - -cdrskin does not contain any bytes copied from cdrecord's sources.

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. - -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 and DVD-R - -DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state -"Sequential Recording". DVD-R are always in sequential state. - -"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 and DVD+R/DL - -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 ia reading drive might show some delay while switching -between both media layers. - - - 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 - -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. - - ------------------------------------------------------------------------------- - Project aspects and legal stuff ------------------------------------------------------------------------------- - -Important Disclaimer : - -This software is provided as is.

If no write mode -is given explicitely 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. -These informations are 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 explicitely 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. 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 explicitely, -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. -.SS -.B Sequentially Recordable DVD Media: -.br -Currently DVD-RW, DVD-R and DVD+R[/DL] can be used for the Sequential recording -model. -.br -This applies to DVD-RW only 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 explicitely by options -.B tsize= -or -.B tao_to_sao_tsize= . -.br -DAO is the only mode for media which do not offer feature 21h Incremental -Streaming. DAO may also be selected explicitely 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 explicitely 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 . -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] resemble those with DVD-R except that with +R -each track gets wrapped in an own session. There is no -dummy writing with -DVD+R[/DL]. -.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 -.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 recognizeable 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, either CD burners or DVD 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. -.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 -.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 on Linux consist of three -numbers: Bus,Target,Lun. 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 on Linux: 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.

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 explicitely 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-RE. -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. -.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 overwriteably 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 and BD-RE. -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-RE 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-RE to reserve a maximum number of spare blocks. -.TP -format_defectmgt_min -Format DVD-RAM or BD-RE 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 seems not to have a speed increasing effect, -though. -.TP -format_defectmgt_payload_ -Format DVD-RAM or BD-RE. 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-RE. -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. -.TP -.BI dev= target -Set the address of the drive to use. Valid are at least the -addresses listed with option --devices, -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 explicitely 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 -.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 preceeded -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 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 or genisoimage. 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 the CD or unformatted DVD-R[W] 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. 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 \-raw96r -Write CD in RAW/RAW96R mode. This mode allows to put more payload bytes -into a CD sector but obviously at the cost of error correction. It can only -be used for tracks of fixely predicted size. Some drives allow this mode but -then behave strange or even go bad for the next few attempts to burn a CD. -One should use it only if inavoidable. -.TP -.BI \-sao -Write CD in Session At Once mode, a sequential DVD-R[W] in Disc-at-once -(DAO) mode, or a DVD+R[/DL]. -.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, BD or DVD+R[/DL] 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 preceeded 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. -.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.

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 \-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 explicitely 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 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 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 programm 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.

It is assumed that this image's inner -size description points to the end of the valuable data. -Overwriteable media with a recognizeable 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 overriden 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 \--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 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 explicitely. -.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 applies to : -.br -Profile 0015h , DVD-R/DL Sequential (will not allow -multi). -.br -If you really test such 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 used for drive command -transactions. Normally this is /dev/sgN on kernel versions < 2.6 and /dev/srN -on kernels >= 2.6 . This option allows to explicitely 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. -.TP -.BI stream_recording="on"|"off" -By setting "on" request that compliance to the desired speed setting is -preferred over management of write errors. With DVD-RAM and BD-RE 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.

Limited cdrecord compatibility wrapper for libburn

-
- -

-

Purpose:

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

-

- -

- -Direct hop to download links -> - -

-

Hardware requirements:

-A CD/DVD/BD recorder suitable for -http://libburnia-project.org
-(SCSI , ATA , USB , or SATA writers compliant to standard MMC-3 for CD -and to MMC-5 for DVD or BD). -
-

- -

-

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.
-
libpthread
-
is supposed to be a standard system component.
-
-

- -

-

-GPL software included:
-

-
-
libburn-0.4.6
-
(founded by Derek Foreman and Ben Jansens, -furthered by team of libburnia-project.org)
-
transfers data to CD and DVD
-
-

- -

-This program system has been tested on Intel/AMD Linux systems only.
-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 except DVD-R DL, cdrskin is able to perform any recording job -which is possible with cdrecord. -Other than with cdrecord, options -multi and -tao are supported with -most DVD types and with BD-RE. -
-

-
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 rw access to the /dev files -as listed by option --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 -toc
- -
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:
-
$ 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 -tao 1.iso -
-
$ cdrskin dev=/dev/hdc -v padsize=300k -multi -tao 2.iso -
-
$ cdrskin dev=/dev/hdc -v padsize=300k -multi -tao 3.iso -
-
$ cdrskin dev=/dev/hdc -v padsize=300k -tao 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 -tao -multi run:
-
$ x=$(cdrskin dev=/dev/sr0 -tao -multi \
-
  --tell_media_space 2>/dev/null)
-
$ echo "Available: $x blocks of 2048 data bytes"
- -
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
-

Example for a setup of device permissions. To be done by the superuser:
-
(CD devices which offer no rw-permission are invisible to normal users.) -
-
# cdrskin --devices
-
...
-
0  dev='/dev/sr0'  rwrwr- :  'TEAC' 'CD-ROM CD-532S'
-
1  dev='/dev/hdc'  rwrw-- :  'LITE-ON' 'LTR-48125S'
-
# chmod a+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 am a long time user of cdrecord and it works 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 not problem with it. -
-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. -

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 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.

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.

Testers for -DVD-R/DL are wanted, though.

For ports to other systems -we would need : login on a development machine resp. a live OS on CD or DVD, -advise from a system person about the equivalent of Linux sg or FreeBSD CAM, -volunteers for testing of realistic use cases. - -We have a well tested code base for burning data and audio CDs and many DVD -types. The burn API is quite comprehensively documented and can be used to -build a presentable application. -We have a functional binary which emulates the core use cases of cdrecord in -order to prove that usability, and in order to allow you to explore libburn's -scope by help of existing cdrecord frontends. - -ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created -and manipulated quite freely. 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. - -@subsection components 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. - libisofs is to be the foundation of our upcoming mkisofs emulation. - -- 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. - -- 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. - -- 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 deletion, renaming, and attribute - changing. An incremental backup feature is provided. - See xorriso/README for more - -- "test" is a collection of application gestures and examples given by the - authors of the library features.

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. By those 2 seconds the MSF -address increases to 00h:02h:00h = LBA 0. - -Each track is represented by an entry -(CTL|ADR, TNO ,01h,DATA FORM,00h, MIN , SEC , FRAME) -TNO gives the track number. MIN, SEC, FRAME give the MSF address which becomes -the start address of the track. 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.

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. Libburnia simply knows no use case where the -correctness of Pre-gap and Post-gap would become evident. - - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- - Overwriteable DVD Cookbook -------------------------------------------------------------------------------- -Inspired by Andy Polyakov's http://fy.chalmers.se/~appro/linux/DVD+RW/tools , -backed by reading mmc5r03c.pdf from http://www.t10.org/ftp/t10/drafts/mmc5/ -by own experiments with drives NEC ND-4570A, LG GSA-4082B, PHILIPS SPD3300L, -and by BD-RE experiments done by Giulio Orsero on LG BE06LU10. - -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-RAM 0012h -DVD-RW Restricted Overwrite 0013h -DVD-RW Sequential Recording 0014h (i.e. unformatted) -DVD+RW 001Ah -BD-RE 0043h - -A short compilation of the write model: -- Overwriting in general - -The recipes described here are depending on formatting state: -- DVD-RAM, fully formatted DVD+RW, DVD-RW, BD-RE -- Unformatted DVD+RW -- Partly formatted DVD+RW -- Unformatted DVD-RW -- Partly formatted DVD-RW -- Intermediate state DVD-RW -- DVD-RAM and BD-RE formatting -- DVD-RAM and BD-RE speed tuning - -------------------------------------------------------------------------------- -Overwriting in general : - -Depending on media type, some kind of formatting has to have happened before -data can be written.

"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.

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/doc/doxygen.conf.in b/doc/doxygen.conf.in deleted file mode 100644 index e36d601..0000000 --- a/doc/doxygen.conf.in +++ /dev/null @@ -1,1300 +0,0 @@ -# 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.

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.

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.

-# 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

(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.

Eventually one should set - a breakpoint in function Smem_protest() to learn about the origin of such - messages. - A status line may be obtained by Smem_report() or printed by Smem_stderr(). - - As long as the variable Smem_record_itemS is set to 0, there is not very much - overhead compared with malloc() and free(). - If the variable is set to 1 by Smem_set_record_items() then all malloc() - results are kept in a list where they will be deleted by their corresponding - Smem_free() calls. If a pointer is to be freed, which is not recorded in the - list then an error message will be printed to stderr. The memory will not - be freed ! - This mode not only may be very slow, it also consumes at least 16 byte per - piece of data which was obtained by malloc as long as it has not been freed. - Due to the current nature of the list, large numbers of memory items are freed - much faster in the reverse order of their creation. If there is a list of - 100000 strings to delete, it is very rewarding to free the youngest ones first. - A shortcut via hashing is available but consumes 24 bytes rather than 16. - (see above Smem_with_hasH ) - - The function Smem_is_recorded() can be used to check wether a pointer is - valid according to the list. It returns : - 0 = is not in list , 1 = is in list , 2 = recording is off - - If one decides to start recording malloc() results in the midst of a program - run, one has to be aware of false protests of Smem_free() if a memory piece - has been allocated before recording started. This will also cause those pieces - to be memory leaks because Smem_free() refuses to delete them. (Freeing memory - that was not obtained by malloc or was already freed previously can result in - deferred SIGSEGV or similar trouble, depending on OS and library.) - Also in that case one should stop recording before ending the program, to - avoid a lot of false complaints about longliving memory objects. - -*/ diff --git a/test/Makefile b/test/Makefile deleted file mode 100644 index 062350d..0000000 --- a/test/Makefile +++ /dev/null @@ -1,4 +0,0 @@ -all clean: - $(MAKE) -C .. -$(MAKEFLAGS) $@ - -.PHONY: all clean diff --git a/test/dewav.c b/test/dewav.c deleted file mode 100644 index 6166bc3..0000000 --- a/test/dewav.c +++ /dev/null @@ -1,215 +0,0 @@ - -/* dewav - Demo of libburn extension libdax_audioxtr - Audio track data extraction facility of libdax and libburn. - Copyright (C) 2006 Thomas Schmitt <scdbackup@gmx.net>, provided under GPL -*/ - -#include <stdio.h> -#include <ctype.h> -#include <sys/types.h> -#include <sys/stat.h> -#include <fcntl.h> -#include <unistd.h> -#include <string.h> -#include <stdlib.h> -#include <errno.h> - - -/* libdax_audioxtr is quite independent of libburn.
