-This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package.  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.

-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.
+libburn.pykix.org is an open-source library for reading, mastering and writing
+optical discs. For now this means only CD-R and CD-RW.

 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.
+Our scope is currently Linux 2.4 and 2.6 and we will have a hard time to widen
+this for now, because of our history. The project could need advise from or
+membership of skilled kernel people and people who know how to talk CD/DVD
+drives into doing things.

-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.

+quite comprehensively documented and can be used to build a presentable

 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.
+           /dev/hdX (e.g. on kernel 2.6).
+           libburn is the foundation of our cdrecord emulation.

 - 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

- 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.
-
- 17th May 2008 an old bug with DVD-RAM and now with BD-RE is fixed by
-  libburn-0.4.8 to allow libisoburn emulation of multisession on those media.

+                              Drive Addressing
+
+Drives get addressed either via their cdrecord-style addresses as listed
+with option -scanbus (see below "Pseudo-SCSI Adresses") or via the paths
+of device files.
+Not only device files listed by --devices may be used but also device files
+which via their major,minor numbers point to the same device driver as
+a listed device file. 
+
+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.
+
+                             Pseudo-SCSI Adresses
+
+cdrecord and cdrskin share the syntax of SCSI addresses but not necessarily
+the meaning of the components. A cdrecord-style address for cdrskin
+  [prefix:]scsibus,target,lun
+can be interpreted in two different modes.
+
+Standard mode tries to be compatible to original cdrecord. This should be true
+with (emulated) SCSI where the /dev/sgN with is looked up with matching
+scsibus,target,lun as given by the operating system.
+With dev=ATA: or dev=ATAPI: the translation to /dev/hdX is purely literal
+but matches the cdrecord addresses on all systems tested so far:
+  X = 'a' + 2 * scsibus + target
+where target only may have the values 0 or 1.
+
+In this mode, option -scanbus will list only SCSI devices unless option
+dev=ATA or dev=ATAPI are given, which will suppress SCSI devices and only
+show IDE drives (i.e. /dev/hdX without ide-scsi emulation).
+
+
+In mode  --old_pseudo_scsi_adr  there is a scsibus,target,lun representation
+which has nothing to do with SCSI and thus is not compatible to cdrecord.
+Each number triple corresponds either to a device file address or to a
+libburn drive number.
+Component "scsibus" indicates the translation method. Defined busses are:
+  0  target is the libburn drivenumber as listed with --devices
+  1  associated to device file /dev/sgN , target chooses N
+  2  associated to device file /dev/hdX , target 0='a', 1='b' ..., 25='z' 
+
+So "1,1,0" is /dev/sg1, "2,3,0" is /dev/hdd, "0,2,0" is libburn drive #2 at
+some unspecified device file. 
+This scheme shall help to keep cdrecord-style addresses stable and exchangeable
+between users without excluding drives with unexpected device addresses.
+The numbering on bus 0 is prone to arbitrary changes caused by changes in
+drive accessability.
+Further busses may emerge as libburn evolves. "prefix" and "lun" may get
+a meaning. To stay upward compatible, use addresses as printed by -scanbus.
+
+                  User Defined Device Address Translation
+
+Some programs or users have their own ideas about the address of their burner.
+K3b 0.10 for example derives cdrecord addresses by own examination of the
+devices and not by calling cdrecord -scanbus.
+Standard mode will hopefully be fully compatible with their ideas.
+
+Old frontends which do not know dev=ATA or dev=ATAPI and which do ask their
+"cdrecord" via -scanbus may be well served with option  --old_pseudo_scsi_adr .
+
+To direct any remaining stubborn callers to the appropriate drives, cdrskin
+allows to define device address aliases. Like
+  cdrskin dev_translation=+1,0,0+/dev/sg1 \
+          dev_translation=+ATA:1,0,0+/dev/sg1 \
+          dev_translation=-"cd+dvd"-0,1,0 \
+          ...
+Any of the addresses dev=1,0,0, dev=ATA:1,0,0, dev=cd+dvd will be mapped to
+/dev/sg1 resp. to 0,1,0.
+The first character after "dev_translation=" defines the character which
+separates the two parts of the translation pair. (Above: "+" and "-".)
+
+In K3b 0.10 it is possible to employ alternative writer programs by setting
+their full path (e.g. /usr/bin/cdrskin) in menu
+  Settings:Configure K3b...:Programs:Search Path 
+and to make them default in menu
+  Settings:Configure K3b...:Programs:Programs:
+A suitable setting for "cdrecord" in menu 
+  Settings:Configure K3b...:Programs:User Parameters
+would then probably be
+  -v dev_translation=+1,0,0+/dev/sg1
+You will learn from button "Show Debugging Output" after a failed burn run
+what cdrecord command was used with what address "dev=...". This address "..."
+will be the right one to replace "1,0,0" in above example.

-                          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 a 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.

-'''cdrskin is the cdrecord compatibility middleware of libburn.'''
+cdrskin-0.2.3 is the cdrecord compatibility middleware of libburn.

 Its paragon, cdrecord, is a powerful GPL'ed burn program included in Joerg
 Schilling's cdrtools. cdrskin strives to be a second source for the services
-traditionally provided by cdrecord. Currently it does CD-R and CD-RW this way.
-Overwriteable media DVD-RAM, DVD+RW, DVD-RW, and BD-RE are handled differently
-than with cdrecord-ProDVD in order to offer TAO-like single track recording.
-Sequential DVD-R[W], DVD+R, DVD+R DL are handled like CD-R[W] with TAO and
-multi-session. Additionally cdrskin offers cdrecord-ProDVD-like mode DAO
-with DVD-R[W].
+traditionally provided by cdrecord. Currently it does CD-R and CD-RW.
+Its future ability to burn DVD media depends on the development of libburn.

 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

 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.

-Advanced multi-session use cases:
-
-A special feature of dvd+rw-tools is growing of ISO-9660 filesystems on
-overwriteable media. This is not the same as multi-session writing of cdrskin
-with CD media, but retrieves additional information from the existing ISO
-image and finally manipulates the start sectors of this existing image.
-
-So, inspired by growisofs, cdrskin can offer DVD multi-session not only with
-sequential DVD-R[W] and with DVD+R [DL], but also with DVD-RAM, DVD+RW, BD-RE
-and even regular disk files or block devices other than CD/DVD writers.
-This is enabled by option --grow_overwriteable_iso.
-
-The libburnia project provides an integrated ISO-9660 multi-session tool
-named [wiki:Xorriso xorriso] which tries to go one step beyond
-growisofs. It uses  [wiki:Libburn libburn] , [wiki:Libisofs libisofs]
-and [wiki:Libisoburn libisoburn].
-
-See [http://scdbackup.sourceforge.net/man_1_xorriso.html man xorriso].
+If there is sincere and well motivated interest, the cdrskin project could try
+to employ growisofs as DVD burning engine. The cdrskin project would prefer to
+wait for DVD support being included in libburn, though.
+A very limited and specialized cdrecord-compatibility wrapper for growisofs
+serves in my project scdbackup. It is not overly hard to make one that serves
+some very few fixed use cases.
+
+To my knowledge, Linux kernels 2.6 do write to DVD+RW via block devices as
+they would write to a traditional tape device. Try old tape archiver
+commands with addresses like /dev/sr0 or /dev/hdc rather than /dev/mt0 .
+I have heard rumors that DVD-RW in mode "restricted overwrite" would be
+block device ready, too. My burner is not a real friend of DVD-RW and
+in an experiment the burn worked fine - but the result was not identical
+to the stream sent to the device. I had similar failure with DVD-RAM, too.
+
+Beware of the impact of a slow block device on overall system i/o buffering.
+It is wise to curb its input to a speed which it is able to deliver to media.
+Else your i/o dedicated RAM might buffer a big amount of stream data.

-dnl    are three small non-negative integers which describe the evolution

-dnl    Older applications are able to use younger libraries over
-dnl    quite a long range of such steps. Some day, nevertheless,
-dnl    compatibility might get terminated, after due notice.
-dnl
-dnl SONAME (libburn.so.4)
-dnl    is a small positive integer which marks a family of compatible
-dnl    evolution steps. Libraries with a particular SONAME allow a binary
-dnl    with the same SONAME to start up. Any further compatibility check is to
-dnl    be done by own runtime means. Especially  *_version() calls in the API
-dnl    which return BURN_MAJOR_VERSION, BURN_MINOR_VERSION, BURN_MICRO_VERSION.
-dnl    See below.

-dnl CURRENT, AGE, REVISION

-dnl    non-negative. The use at runtime is not known yet. But libtool computes
-dnl    at build time  SONAME = CURRENT - AGE.
-dnl    So this is a superspace of the SONAME version space. To avoid
-dnl    ill SONAME, the value of  CURRENT must be larger than AGE.

-dnl    REVISION= LT_REVISION
-dnl
-dnl Beginning with libburn-0.4.1 a rectified counting was introduced as
-dnl    CURRENT=10, REVISION=1, AGE=6
-dnl This rectification declared that version to be binary compatible up
-dnl from libburn-0.3.4.
-dnl Real compatibility was given since libburn-0.3.2.
-dnl Beware of libburn-0.2.6 which had SONAME=6 and is not binary compatible.
-dnl Applications for libburn-0.2 to libburn-0.3.1 need recompilation but no
-dnl source code changes.

-dnl Neatly versioned stable releases meanwhile:
-dnl    0.4.2 = libburn.so.4.7.0

-dnl    0.4.8 = libburn.so.4.13.0
-dnl
-dnl So LT_CURRENT, LT_REVISION and LT_AGE get set directly here.
-dnl SONAME of the emerging library is  LT_CURRENT - LT_AGE.
-dnl The linker will do no finer checks. Especially no age range check for
-dnl the application binary. If SONAME matches, then the couple starts.
-dnl 
-dnl Therefore at run time info is provided by libburn function burn_version().
-dnl It returns the major, minor and micro revision of the library.
-dnl Before using any API feature, a program should check for age.
-dnl
-dnl The variables BURN_*_VERSION are mere copies for informing libtool.
-dnl The true values which get issued and should be compared are macros

+optical discs. For now this means only CD-R and CD-RW.

 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.
+Our scope is currently Linux 2.4 and 2.6 and we will have a hard time to widen
+this for now, because of our history. The project could need advise from or
+membership of skilled kernel people and people who know how to talk CD/DVD
+drives into doing things.

-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.
+           /dev/hdX (e.g. on kernel 2.6).
+           libburn is the foundation of our cdrecord emulation.

 - 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.
+           the services traditionally provided by 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. The burn API example of libburn
-           is named test/libburner.c . The API for media information inquiry is
-           demonstrated in test/telltoc.c .
+           authors of the library features. The main API example of libburn
+           is named test/libburner.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).
+We plan to be a responsive upstream. Bear with us.

+Our build system is based on autotools.

+
+To build libburn and its subprojects it should be sufficient to go into
+its toplevel directory and execute

+-  ./bootstrap  (needed if you downloaded from SVN)
+
+-  ./configure
+
+-  make
+
+To make the libraries accessible for running resp. developing applications 
+
+-  make install
+

+Thus we expect them to be useable by a wide range of Linux-implemented
+languages and development tools.

-Users of modern desktop Linux installations report misburns with CD/DVD
-recording due to concurrency problems.
-
-This text describes two locking protocols which have been developed by our
-best possible effort. But finally they rather serve as repelling example of
-what would be needed in user space to achieve an insufficient partial solution.
-
-Ted Ts'o was so friendly to help as critic with his own use cases. It turned
-out that we cannot imagine a way in user space how to cover reliably the needs
-of callers of libblkid and the needs of our burn programs.
-
-------------------------------------------------------------------------------
-Content:
-
-The "Delicate Device Locking Protocol" shall demonstrate our sincere
-consideration of the problem.
-
-"What are the Stumble Stones ?" lists reasons why the effort finally failed.
-
-----------------------------------------------------------------------------
-
-
-                      Delicate Device Locking Protocol
-               (a joint sub project of cdrkit and libburnia)
-                       (contact: scdbackup@gmx.net )
-
-Our projects provide programs which allow recording of data on CD or DVD.
-We encounter an increasing number of bug reports about spoiled burn runs and
-wasted media which obviously have one common cause: interference by other
-programs which access the drive's device files.
-There is some riddling about which gestures exactly are dangerous for
-ongoing recordings or can cause weirdly misformatted drive replies to MMC 
-commands. 
-We do know, nevertheless, that these effects do not occur if no other program
-accesses a device file of the drive while our programs use it. 
-
-DDLP shall help to avoid collisions between programs in the process of
-recording to a CD or DVD drive and other programs which access that drive.
-The protocol intends to provide advisory locking. So any good-willing program
-has to take some extra precautions to participate.
-
-If a program does not feel vulnerable to disturbance, then the precautions
-impose much less effort than if the program feels the need for protection.
-
-Two locking strategies are specified:
-DDLP-A operates on device files only. It is very Linux specific.
-DDLP-B adds proxy lock files, inspired by FHS /var/lock standard.
-
-
-                                  DDLP-A
-
-This protocol relies on the hardly documented feature open(O_EXCL | O_RDWR)
-with Linux device files and on POSIX compliant fcntl(F_SETLK).
-
-Other than the original meaning of O_EXCL with creating regular files, the
-effect on device files is mutual exclusion of access. I.e. if one
-filedescriptor is open on that combination of major-minor device number, then
-no other open(O_EXCL) will succeed. But open() without O_EXCL would succeed.
-So this is advisory and exclusive locking.
-With kernel 2.6 it seems to work on all device drivers which might get used
-to access a CD/DVD drive.
-
-The vulnerable programs shall not start their operation before they occupied a
-wide collection of drive representations.
-Non-vulnerable programs shall take care to detect the occupation of _one_ such
-representation.
-
-                          So for Friendly Programs
-
-A program which does not feel vulnerable to disturbance is urged to access
-CD/DVD drives by opening a file descriptor which will uphold the lock
-as long as it does not get closed. There are two alternative ways to achieve
-this.
-Very reliable is  
-
-  open( some_path , O_EXCL | ...)
-
-But O_EXCL imposes restrictions and interferences:
- O_EXCL | O_RDONLY does not succeed with /dev/sg* !
- O_EXCL cannot provide shared locks for programs which only want to lock
-  against burn programs but not against their own peers.
- O_EXCL keeps from obtaining information by harmless activities.
- O_EXCL already has a meaning with devices which are mounted as filesystems.
-  This priority meaning is more liberal than the one needed for CD/DV recording
-  protection.
-
-So it may be necessary to use a cautious open() without O_EXCL and to aquire
-a POSIX lock via fcntl(). "Cautious" means to add O_NDELAY to the flags of
-open(), because this is declared to avoid side effects within open().
-
-With this gesture it is important to use the paths expected by our burn
-programs: /dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z]
-because fcntl(F_SETLK) does not lock the device but only a device-inode.
-
-  std_path = one of the standard device files:
-               /dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z]
-             or a symbolic link pointing to one of them.
-  open( std_path , ... | O_NDELAY)
-  fcntl(F_SETLK) and close() on failure
-  ... eventually disable O_NDELAY by fcntl(F_SETFL) ...
-
-There is a pitfall mentioned in man 2 fcntl :
- "locks are automatically released [...] if it closes any file descriptor
-  referring to a file on which locks are held. This is bad [...]"
-So you may have to re-lock after some temporary fd got closed.
-
-
-                            Vulnerable Programs
-
-For programs which do feel vulnerable, O_EXCL would suffice for the /dev/hd*
-device file family and their driver. But USB and SATA recorders appear with
-at least two different major-minor combinations simultaneously.
-One as /dev/sr* alias /dev/scd*, the other as /dev/sg*.
-The same is true for ide-scsi or recorders attached to SCSI controllers.
-
-So, in order to lock any access to the recorder, one has to open(O_EXCL)
-not only the device file that is intended for accessing the recorder but also
-a device file of any other major-minor representation of the recorder.
-This is done via the SCSI address parameter vector (Host,Channel,Id,Lun)
-and a search on standard device file paths /dev/sr* /dev/scd* /dev/sg*.
-In this text the alternative device representations are called "siblings".
-
-For finding them, it is necessary to apply open() to many device files which
-might be occupied by delicate operations. On the other hand it is very
-important to occupy all reasonable representations of the drive.
-So the reading of the (Host,Channel,Id,Lun) parameters demands an 
-open(O_RDONLY | O_NDELAY) _without_ fcntl() in order to find the outmost
-number of representations among the standard device files. Only ioctls
-SCSI_IOCTL_GET_IDLUN and SCSI_IOCTL_GET_BUS_NUMBER are applied.
-Hopefully this gesture is unable to cause harmful side effects on kernel 2.6.
-
-At least one file of each class sr, scd and sg should be found to regard
-the occupation as satisfying. Thus corresponding sr-scd-sg triplets should have
-matching ownerships and access permissions.
-One will have to help the sysadmins to find those triplets.
-
-A spicy detail is that sr and scd may be distinct device files for the same
-major-minor combination.  In this case fcntl() locks on both are needed
-but O_EXCL can only be applied to one of them.
-

-
-Put ddlpa.h and ddlpa.c into the same directory and compile as test program by
-  cc -g -Wall -DDDLPA_C_STANDALONE -o ddlpa ddlpa.c
-
-Use it to occupy a drive's representations for a given number of seconds
-  ./ddlpa /dev/sr0 300
-
-It should do no harm to any of your running activities.
-If it does: Please, please alert us.
-
-Your own programs should not be able to circumvent the occupation if they
-obey above rules for Friendly Programs.
-Of course ./ddlpa should be unable to circumvent itself.
-
-A successfull occupation looks like
-  DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/scd0") = "/dev/sr0"
-  DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sr0"

-  ddlpa: opened           /dev/sr0
-  ddlpa: opened siblings: /dev/scd0 /dev/sg0
-  slept 1 seconds of 300
-
-Now an attempt via device file alias /dev/NEC must fail:
-  DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/NEC") = "/dev/sg0"
-  DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sr0"
-  DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/scd0"

-  Cannot exclusively open '/dev/sg0'
-  Reason given    : Failed to open O_RDWR | O_NDELAY | O_EXCL : '/dev/sr0'
-  Error condition : 16 'Device or resource busy'
-
-With hdc, of course, things are trivial
-  DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/hdc") = "/dev/hdc"
-  DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/hdc'
-  ---------------------------------------------- Lock gained
-  ddlpa: opened           /dev/hdc
-  slept 1 seconds of 1
-
-
-Ted Ts'o provided program  open-cd-excl  which allows to explore open(2) on
-device files with combinations of read-write, O_EXCL, and fcntl().
-(This does not mean that Ted endorsed our project yet. He helps exploring.)
-
-Friendly in the sense of DDLP-A would be any run which uses at least one of
-the options -e (i.e. O_EXCL) or -f (i.e. F_SETLK, applied to a file
-descriptor which was obtained from a standard device file path).
-The code is available under GPL at
-  http://libburnia.pykix.org/browser/libburn/trunk/test/open-cd-excl.c?format=txt
-To be compiled by
-  cc -g -Wall -o open-cd-excl open-cd-excl.c
-
-Options:
-  -e : open O_EXCL
-  -f : aquire lock by fcntl(F_SETLK) after sucessful open
-  -i : do not wait in case of success but exit 0 immediately
-  -r : open O_RDONLY , with -f use F_RDLCK
-  -w : open O_RDWR   , with -f use F_WRLCK
-  plus the path of the devce file to open.
-
-Friendly Programs would use gestures like:
-  ./open-cd-excl -e -r /dev/sr0
-  ./open-cd-excl -e -w /dev/sg1

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

-  libdax_msgs is designed to serve in libraries which want to offer their
-  applications a way to control the output of library messages. It shall be
-  incorporated by an owner, i.e. a software entity which encloses the code
-  of the .c file.
-
-  Owner of libdax_msgs is libburn. A fully compatible variant named libiso_msgs
-  is owned by libisofs and can get generated by a script of the libburn
-  project: libburn/libdax_msgs_to_xyz_msgs.sh .
-
-  Reason: One cannot link two owners of the same variant together because
-  both would offer the same functions to the linker. For that situation one
-  has to create a compatible variant as it is done for libisofs.
-
-  Compatible variants may get plugged together by call combinations like
-    burn_set_messenger(iso_get_messenger());
-  A new variant would demand a _set_messenger() function if it has to work
-  with libisofs. If only libburn is planned as link partner then a simple
-  _get_messenger() does suffice.
-  Take care to shutdown libburn before its provider of the *_msgs object
-  gets shut down.

-This is the main operating system dependent SCSI part of libburn. It implements
-the transport level aspects of SCSI control and command i/o.
-
-Present implementation: FreeBSD CAM (untested)
-
-
-PORTING:
-
-Porting libburn typically will consist of adding a new operating system case
-to the following switcher files:
-  os.h    Operating system specific libburn definitions and declarations.
-  sg.c    Operating system dependent transport level modules.
-and of deriving the following system specific files from existing examples:
-  os-*.h  Included by os.h. You will need some general system knowledge
-          about signals and knowledge about the storage object needs of your
-          transport level module sg-*.c.
-
-  sg-*.c  This source module. You will need special system knowledge about
-          how to detect all potentially available drives, how to open them,
-          eventually how to exclusively reserve them, how to perform
-          SCSI transactions, how to inquire the (pseudo-)SCSI driver.
-          You will not need to care about CD burning, MMC or other high-level
-          SCSI aspects.
-
-Said sg-*.c operations are defined by a public function interface, which has
-to be implemented in a way that provides libburn with the desired services:
- 
-sg_give_next_adr()      iterates over the set of potentially useful drive 
-                        address strings.
-
-scsi_enumerate_drives() brings all available, not-whitelist-banned, and
-                        accessible drives into libburn's list of drives.
-
-sg_drive_is_open()      tells wether libburn has the given drive in use.
-
-sg_grab()               opens the drive for SCSI commands and ensures
-                        undisturbed access.
-
-sg_release()            closes a drive opened by sg_grab()
-
-sg_issue_command()      sends a SCSI command to the drive, receives reply,
-                        and evaluates wether the command succeeded or shall
-                        be retried or finally failed.
-
-sg_obtain_scsi_adr()    tries to obtain SCSI address parameters.
-
-burn_os_stdio_capacity()  estimates the emulated media space of stdio-drives.
-
-
-Porting hints are marked by the text "PORTING:".
-Send feedback to libburn-hackers@pykix.org .

-Description of the helper program stic*/bin/cgen
-
-cgen is copyright 2001 to 2007, Thomas Schmitt <stic-source@gmx.net>
-and provided under BSD license.
-
-Compilation:
-  cc -g -o cgen cgen.c ctyp.c smem.c
-
-
-cgen produces a class stub in C programming language. The data structure of
-the class is described by some lines which get read from stdin. The stub will
-consist of four files which emerge in the current working directory:
- <classname>.h          public header file of the class
- <classname>.c          automatically generated C code of the class
-                        plus a copy of <classname>.c.methods
- <classname>_private.h  private header file of the class
- <classname>.c.methods  safe storage for manually created functions.
-                        From here they get copied into the generated stub.
-                        If such a file is missing, a dummy gets created.
-It will define a struct <ClassnamE> for representing the class data aspects,
-construtor <Classname>_new(), destructor <Classname>_destroy(),
-getter <Classname>_<element>_get() for each structure element.
-Some more functions get added for particular class and element roles.
-
-cgen normally refuses to overwrite existing files because it supposes that
-those contain code added by the human programmer. 
-Human programmer enhancements may be explanatory comments, class specific
-methods, initial element values and other special precautions within the
-generated functions.
-As long as the modelling phase is going on, one may store such human code
-in <classname>.c.methods and may use command line option -overwrite for
-modelling development cycles.
-
-At some point of model matureness one may decide to give up cgen and the
-.c.method files and to go on only with _private.h , .h and .c files.
-
-
-Command line options
-
-  -no_stic   prevents usage of stic_dir/s_tools/*.[ch]
-
-  -ansi      generates ANSI C function heads and makes file <classname>.h hold
-             only public definitions: an opaque declaration of the class struct
-             and a list of function prototypes. The definiton of the class
-             struct is then in <classname>_private.h .
-  -global_include filename
-             sets the name of a file which will contain globally necessary
-             declarations. Currently it lists the existence of all class
-             structs.
-  -lowercase generate struct <classname> rather than struct <ClassnamE> and
-             function names <classname>_func() rather than <Classname>_func() .
-  -overwrite allows to overwrite files <classname>_private.h, <classname>.h
-             and <classname>.c, but not <classname>.c.methods.
-
-
-Input line format:
-
-There are two states of input: class level and element level.
-Exampes are shown below with class roles and element roles.
-
-Input starts at class level. A class level line may be one of
-
- Comment. A line which begins with '#' is ignored on class level.
-
- Empty. A line with no characters is a comment with empty text (i.e. ignored).
-
- Class. Options which begin with '-' and finally a word in lowercase letters
-  which defines the <classname>. The classname leads to a struct ClassnamE
-  and some class methods implemented as C functions <Classnname>_<func>().
-
- End of input. Line "@@@" or EOF at stdin end the program run.
-
-After a class line, input switches to element level where a line may be:
-
- Comment. A line which after some white space begins with '#' is considered
-  a comment. The preceeding white space is ignored and the text after '#' is
-  eventuellay trimmed by a single blank at both ends. This text will be part
-  of the class struct definition within file <classname_private>.h as a single
-  C comment line /* ... */. The sequence of elements and comments is preserved.
-  An empty comment text leads to an empty line in <classname_private>.h.
-
- Empty. A line with no characters is a comment with empty text.
-
- Element. Options which begin with '-', eventual C keywords "unsigned" or
-  "volatile", type or "struct <NamE>", element name. This leads to a struct
-  element which is taken into respect in some class methods. Depending on the
-  options in this line, some element methods <Classnname>_<func>_<element>()
-  may get generated.
-
- End of class. A single '@' marks the end of the element list and brings
-  input back to class level. I.e. next is expected another class name or
-  "@@@" or EOF at stdin.
-
-Input semantics:
-
-A class can have one of two roles:
-
- Standalone class.
-  Input example:
-    my_class
-
- Listable class, which has pointers to peer instances: .prev and .next
-  Such classes get a list destructor <Classname>_destroy_all() which destroys
-  all members of a list (which is given by any of the list members).
-  Such a class should have a pointer *boss as first element in which case
-  the constructor will look like
-    <Classname>_new(struct <ClassnamE> **o,struct <Some_clasS> *boss,int flag);
-  There is a function <Classname>_link() which inserts an instance into a list
-  and a function <Classname>_count() which tells the number of list members.
-  For pseudo random access there is function <Classname>_by_idx().
-  Input example:
-    -l my_class
-
-
-A modifier is defined for classes:
-
- Bossless. Disables a special boss-subordinate relationship which is created
-  if the first element of a class is a struct pointer with the name "boss".
-  Like
-    -l <classname>
-    -v struct Some_clasS *boss
-  Normally such a parameter *boss becomes part of the constructor method
-    <Classname>_new(struct <ClassnamE> **o, struct Some_clasS *boss, int flag);
-  This relationship is typical for a listable class and a single class which
-  is designed to host instances of that listable class. Therefore one gets a
-  warning if a listable class does not begin with a struct pointer *boss.
-  But if -b is given, then CgeN ill not include a parameter *boss into the
-  constructor. It will rather look normal:
-    <Classname>_new(struct <ClassnamE> **o, int flag);
-  It will not warn if the first element of a listable class is not struct
-  pointer *boss.
-
-
-Elements have one of the following roles:
-
- Value. It provides only storage for a C data type (which may be a C pointer
-  despite the role name "value"), a getter method <Classname>_<element>_get(),
-  and a setter method <Classname>_<element>_set().
-  Input examples:
-    -v int i
-    -v int a[100]
-    -v char *cpt
-    -v struct xyz x
-    -v struct xyz *xpt
-
- Managed. This has to be a pointer to a struct <XyZ> or to char. It will not
-  get attached to an object by the stub's code but its destructor
-  <Xyz>_destroy() will be called by <Classname>_destruct(). In case of (char *)
-  it is supposed that a non-NULL value has been allocated by malloc().
-  Managed (char *) types get a setter function <Classname>_<element>_set()
-  which allocates memory and copies the textstring from its parameter.
-  Input examples:
-    -m struct XyZ *xyzpt
-    -m char *textstring
-
- Chainlink. A pair of prev-next-style pointers to the own class struct.
-  Function <Classname>_destruct() will unlink the affected instance and
-  put together its link partners.
-  Input example (there must always be two consequtive -c lines):
-    -c struct My_clasS *up
-    -c struct My_clasS *down
-
- List. A pair of pointers to the struct <XyZ> of a listable class. The first
-  one <ls> holds the start of the list, the second one <eol> holds the end.
-  The getter function has an additional argument idx:
-    <Classname>_get_<ls>(struct <ClassnamE> *o, int idx, struct <XyZ> **pt,
-                         int flag)
-  idx == 0 is the start of the list, idx=1 the next element, ...
-  idx == -1 retrieves the last element of the list.
-  For insertion of list items there is provided method <Classname>_new_<ls>().
-  The inserted item is reachable via the getter function with idx == -1
-  <Classname>_destroy() instance calls <Xyz>_destroy_all(). Note that the end
-  pointer is always generated as private element (-p).
-  Input example (there must always be a -l and a -v line):
-    -l struct XyZ *list_start
-    -v struct XyZ *list_end
-
-The availability of getter method <Classname>_get_<element>(), and setter
-method <Classname>_set_<element>_set() can be controled by two modifiers:
-
- Readonly. Only a getter method.
-  Input example
-    -r -v int broadcasted_status
-
- Private. Neither getter nor setter method.
-  Input example
-    -p -v int private_value
-
- Bossless listable. This marks elements which are listable objects but do not
-  expect a boss pointer in their constructor. See above: Listable class and
-  the bossless modifier for classes.
-  Input example
-    -b -l struct XyZ *list
-    -v struct XyZ *last_in_list
-
- Initialization free. The class constructor will not initialize this element.
-  This modifier has to be used if neither NULL nor 0 are suitable
-  initialization values.
-
-Example run:
-
-  rm  class_x.c  class_x.h  class_y.c  class_y.h
-  bin/cgen <<+
-l class_x
-r -v struct Boss_clasS *boss
-v int x
-r -v struct stat stbuf
-m struct Class_Y *y
-m char *text
-c struct Class_X *master
-c struct Class_X *slave
-b -l struct Class_X *provider
-p -v struct Class_X *last_provider
-@
-b -l class_y
-r -v char providername[80]

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

-Notes:
----------------------------------------------------------------------------
-
- Compile cgen:
-   ( cd libcevap && cc -g -o cgen cgen.c ctyp.c smem.c )
-
- Generate C stubs:
-   ( cd libcevap && ./libcevap_gen.sh )
- Option -lowercase would generate all lowercase struct and function names
-
- Compile test:
-   ( cd libcevap && ( rm a.out ; cc -g main.c cevap*.c smem.c ) )
- Option -DCevap_lowercasE would tell main.c that -lowercase was used above.
-
-
----------------------------------------------------------------------------
-
-For a description of CgeN see libcevap/cgen.txt
-
-The generated code uses smem.[ch] out of one of my BSD licensed projects.
-For a description see end of libcevap/smem.h .

-
- Functions to replace  malloc()  and  free() in order to get more control
- over memory leaks or spurious errors caused by faulty usage of malloc()
- and free(). 
-
-
- Sourcecode provisions:
- 
- Use only the following macros for memory management:
-    TSOB_FELD(type,count)  creates an array of items of given type 
-    Smem_malloC()          analogue of malloc()
-    Smem_freE()            analogue of free()
- One may #define malloc Smem_malloC resp. #define free Smem_freE 
- but better would be to review (and often to streamline) the sourcecode
- in respect to those two functions. 
-
-
- Speed versus control:
-
- In production versions, where maximum speed is required, one may undefine
- the macro  Smem_own_functionS  in  smem.h . 
- This causes the above macros to directly invoke malloc() and free() without
- any speed reduction (and without any additional use).
- Undefinitio can be done globaly by modifying smem.h or locally by defining
-  Smem_no_own_functionS  before including smem.h .
-
- If Smem_own_functionS remains defined, then the functions
-   Smem_malloc() 
-   Smem_free()
- are used rather than malloc() and free().
- They count the number of calls to maintain a rough overview of memory usage.
- Smem_malloc() additionally checks for 0 size and Smem_free() checks for
- NULL pointers, which they both report to stderr. 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.
