+Installation Instructions

+
+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.

+DVD+RW and DVD-RAM 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). Currently
+there is no difference between -sao and -tao. If ever, then -tao will be the
+mode which preserves the current behavior.
+
+For these media, -msinfo alone would not be enough to perform appending of an
+ISO filesystem. The filesystem driver will need a hint to find the start of the
+most recent session. For example put an ISO filesystem at address 1 GB:
+  mkisofs -C 0,524288 ... | \
+  cdrskin dev=/dev/sr0 -v fs=32m -eject speed=4 write_start_address=524288s -
+The superuser may then do:
+  mount -t iso9660 -o ro,sbsector=524288 /dev/sr0 /mnt
+Note: On my linux-2.4.21-215 mount works only with sbsector <= 337920 (660 MB).
+To extend a filesystem already existing at address 0
+  mkisofs -C 0,524288 -M /dev/sr0 ... | cdrskin dev=/dev/sr0 ...
+Record the number 524288 for usage as first number with -C at the next
+extension:
+  mkisofs -C 524288,1000000 ... | cdrskin write_start_address=1000000s ...
+
+Program growisofs can append to an ISO filesystem on DVD+RW by additionally
+manipulating the first session. cdrskin does not want to get involved so deep
+into the format of the burned data. Be advised to use growisofs for the
+task of maintaining extendable ISO-Filesystems on DVD+RW. 
+
+
+                               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 MB. 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.

+.SH NAME
+cdrskin \- burns preformatted data to CD-R, CD-RW, DVD-R, DVD-RW, DVD+RW,
+DVD-RAM via libburn.
+.SH SYNOPSIS
+.B cdrskin
+.RI [ options | track_source_addresses ]
+.br
+.SH DESCRIPTION
+.PP
+.\" TeX users may be more comfortable with the \fB<whatever>\fP and
+.\" \fI<whatever>\fP escape sequences to invode bold face and italics, 
+.\" respectively.
+.PP 
+\fBcdrskin\fP is a program that provides some of cdrecord's options
+in a compatible way for CD media. With DVD it has its own ways.
+You do not need to be superuser for its daily usage.
+.PP
+.B Overview of features:
+.br
+Blanking of CD-RW and DVD-RW.
+.br
+Burning of data or audio tracks to CD,
+.br
+either in versatile Track at Once mode (TAO)
+.br
+or in Session at Once mode for seamless tracks.
+.br
+Multi session on CD (follow-up sessions in TAO only)
+.br
+and on DVD-RW or DVD-R (in Incremental write mode only).
+.br
+Single session on DVD-RW or DVD-R (Disk-at-once)
+.br
+or on overwriteable DVD+RW, DVD-RW, DVD-RAM.
+.br
+Bus scan, burnfree, speed options, retrieving media info, padding, fifo.
+.br
+See section EXAMPLES at the end of this text.
+.PP
+.B Track recording model:
+.br
+The input-output entities which get processed are called tracks.
+A \fBtrack\fP stores a stream of bytes.
+.br
+Each track is initiated by one track source address argument, which may either
+be "-" for standard input or the address of a readable file. 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 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.
+.PP
+.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
+There are two write modes,
+.B -tao
+and
+.B -sao .
+.br
+-tao allows to use track source 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.
+.PP
+.B Sequentially Recordable DVD Media:
+.br
+Currently only DVD-RW and DVD-R can be used for the Sequential recording model.
+DVD-RW must be 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
+Incremental Streaming is the default write mode if it is offered by the media.
+It 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 other write 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 default mode for media which do not offer feature 21h Incremental
+Streaming. It may also be selected explicitely by option
+.B -sao .
+.br
+Program growisofs uses DAO on sequential DVD-R[W] media for maximum
+DVD-ROM/-Video compatibility.
+.PP
+.B Overwriteable DVD Media:
+.br
+Currently only types DVD+RW, DVD-RW and DVD-RAM can be overwritten via cdrskin.
+.br
+DVD+RW and DVD-RAM media get treated as blank media regardless wether they
+hold data or not. They need no special initial formatting.
+Options -audio and -multi are not allowed. Only one track is allowed.
+-toc does not return information about the media content.
+Currently there is no difference between -sao and -tao. If ever, then -tao
+will be the mode which preserves the current behavior.
+.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 option
+blank=deformat_sequential 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.
+.PP
+.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 superuser who is able to get this list without further
+precautions.
+.br
+It is consensus that \fBchmod a+rw /dev/sg0\fP or \fBchmod a+rw /dev/hdc\fP
+is less security sensitive than chmod u+s /usr/bin/cdrskin. The risk for the
+drive is somewhat higher but the overall system is much less at stake.
+.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/sr0).

+.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.
+.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.
+.TP 
+.BI blank= type
+Blank a CD-RW, a DVD-RW, or format a DVD+/-RW.
+This is combinable with burning in the same run of cdrskin.
+The type given with blank= selects the particular behavior:
+.RS
+.TP
+help
+Print this list of blanking types.
+.TP
+all
+Blank an entire CD-RW or an unformatted DVD-RW.
+(See also --prodvd_cli_compatible)
+.TP
+fast
+Minimally blank an entire CD-RW or blank an unformatted DVD-RW.
+(See also --prodvd_cli_compatible)
+.TP
+format_overwrite
+Format a DVD-RW to "Restricted Overwrite". The user should bring some patience.
+.br
+(Note: blank=format_overwrite* are not original cdrecord options.)
+.TP
+format_overwrite_quickest
+Like format_overwrite without creating a 128 MB 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 MB.
+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
+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. 
+.br
+(Note: blank=deformat_sequential* 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).
+.RE
+.TP
+.BI \-checkdrive
+Retrieve some info about the addressed drive.
+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 guarantee that this will work with a particular combination
+of drive, media, and write mode. Blanking is prevented reliably, though.
+.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 with blank=format_* to enforce re-formatting of media
+which appear to be sufficiently formatted already.
+.br
+Use this only when in urgent need.
+.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 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 besides 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.
+.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 overwriteable DVD media and 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. 
+.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 kB 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, resp. a sequential DVD-R[W] in Disc-at-once
+(DAO) mode.
+.br
+With CD this mode is able to put several audio tracks on media without
+producing audible gaps between them.
+.br
+With DVD-R[W] this mode can only write a single track.
+No -multi is allowed with DVD-R[W] -sao.
+.br
+-sao 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.
+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.
+.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, resp. sequential DVD-R[W] in Incremental
+Streaming mode. This mode also applies pro-forma to overwriteable DVD 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. Retrieve an afio archive from track number 2:
+.br
+tracknumber=2
+.br
+lba=$(cdrskin dev=/dev/cdrom -toc 2>&1 | \\
+.br

+.br
+awk '{ print $4}' )
+.br
+dd if=/dev/cdrom bs=2048 skip="$lba" | \\
+.br
+afio -t - | less
+.RE
+.TP
+.BI tsize= size
+Announces the exact size of the next track source. This is necessary with any
+write mode other than -tao if the track source is not a regular disk file, but
+e.g. "-" (standard input) or a named pipe.
+About size specifiers, see option fs=.
+.br
+If the track source does not deliver the predicted amount of bytes, the
+remainder of the track is padded with zeros. This is not considered an error.
+If on the other hand the track source delivers more than the announced bytes
+then the track on media gets truncated to the predicted size and cdrskin exits
+with non-zero value.
+.TP
+.BI \-v
+Increment verbose level by one. Startlevel is 0 with only few messages.
+Level 1 prints progress report with long running operations and also causes
+some extra lines to be put out with info retrieval options. 
+Level 2 additionally reports about option settings derived from arguments or
+startup files. Level 3 is for debugging and useful mainly in conjunction with
+somebody who had a look into the program sourcecode.
+.PP
+Alphabetical list of options which are genuine to cdrskin and intended for
+normal use:
+.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 \--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 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 \--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 write_start_address= byte_offset
+Set the address on media where to start writing the track. With DVD+RW or
+DVD-RAM byte_offset must be aligned to 2 KB blocks, but better is 32 kB.
+With DVD-RW 32 kB 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 dev_translation= <sep><from><sep><to>
+Set drive address alias. This was necessary before cdrskin-0.2.4 to manually
+translate cdrecord addresses into cdrskin addresses.
+.br
+<sep> is a single character which may not occur in the address string
+<from>. <from> is an address as expected to be given by the user via option
+dev=. <to> is the address to be used instead whenever <from> is given.
+More than one translation instruction can be given in one cdrskin run.
+.br
+E.g.: dev_translation=+ATA:1,0,0+/dev/sg1 dev_translation=+ATA:1,1,0+/dev/sg2
+.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_not_exclusive
+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_exclusive
+Linux specific:
+Try to exclusively reserve device files /dev/srN, /dev/scdM, /dev/stK of drive.
+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 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 \--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/sr0 using the same SCSI address as /dev/sg0.)
+.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.

+volunteers for testing of realistic use cases.

+libburner has two companions, telltoc and dewav, which help to perform some

+
+telltoc prints a table of content (sessions, tracks and leadouts), it tells
+about type and state of media, and also is able to provide the necessary
+multi-session information for program mkisofs option -C. Especially helpful
+are its predictions with "Write multi" and "Write modes" where availability
+of "TAO" indicates that tracks of unpredicted length can be written.
+See: test/telltoc --help.
+
+dewav extracts raw byte-swapped audio data from files of format .wav (MS WAVE)
+or .au (SUN Audio). See example in libburner --help.

-   @mainpage Libburn Documentation Index
-
-   @section intro Introduction
-
-Libburn 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 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 do have a workable code base for burning data CDs, though. The burn API is
-quite comprehensively documented and can be used to build a presentable
-application.
-We do have a functional binary which emulates parts 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.
-
-@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/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.
-
-- 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.
-           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.
-
-- "test"   is a collection of application gestures and examples given by the
-           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 plan to be a responsive upstream. Bear with us.
-
-
-   @section using Using the libraries
-
-Our build system is based on autotools.
-User experience tells us that you will need at least autotools version 1.7.
-
-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
-
-Both libraries are written in C language and get built by autotools.
-Thus we expect them to be useable by a wide range of Linux-implemented
-languages and development tools.
-
-
-@section libburner Libburner
-
-libburner is a minimal demo application for the library libburn 
-(see: libburn/libburn.h) as provided on  http://libburn.pykix.org .
-It can list the available devices, can blank a CD-RW and
-can burn to CD-R or CD-RW.
-
-It's main purpose, nevertheless, is to show you how to use libburn and also
-to serve the libburn team as reference application. libburner does indeed
-define the standard way how above three gestures can be implemented and
-stay upward compatible for a good while.

+- Writing a session to CD in TAO mode
+- Obtaining CD multi-session info for extending ISO-9660 filesystems
+- Obtaining a Table Of Content from CD
+
+
+-------------------------------------------------------------------------------
+About blank, appendable and finalized CD media :
+
+CD media have to be blank or appendable in order to be writeable in TAO mode.
+The according status may be inquired by 51h READ DISC INFORMATION requesting
+Data Type 000b Standard Disc Information, where reply value Disc Status
+indicates:
+ 00b   blank
+ 01b   appendable
+ 10b   finalized
+ 11b   others (unsuitable for this recipe)
+(mmc5r03c.pdf 6.22.3.1.4)
+
+CD-RW which are finalized or appendable may be blanked by command A1h BLANK
+with blanking types 000b "Blank the disc" or 001b "Minimally blank the disc".
+The Start Address/Track Number will be ignored so it may well be 0.
+
+Because the operation is long running it is advised to set the Immed bit and to
+watch the progress by commands 00h TEST UNIT READY and 03h REQUEST SENSE
+with DESC bit set to 0 for fixed format reply.
+It is done when 00h succeeds and 03h reports 0 in PROGRESS INDICATION 
+(byte 1+2 in Table 22 = byte 16+17 SENSE KEY SPECIFIC in table 26).
+(mmc5r03c.pdf 6.2 BLANK)
+(spc3r23.pdf 4.5.2.4.4 table 22, 4.5.3 table 26,
+             6.27 REQUEST SENSE, 6.33 TEST UNIT READY)
+
+
+-------------------------------------------------------------------------------
+Writing a session to CD in TAO mode :
+
+The writing method for blank or appendable media is the same. A new session
+will get created automatically by the first track when it is written. If the
+media is blank then the new session will be the first and only one in the
+table of content. If the media is appendable then a new session will be
+appended to the existing sessions. In any case the new track will be the
+first one in the new session.
+
+Speed may be set by BBh SET CD SPEED parameter Drive Write Speed. Note that
+kbytes/sec means 1000 bytes/sec and not 1024/sec. Rotational control should
+be set to 00b. 1x CD speed is 176.4 kbytes/sec. Speed is usually set to the
+next lower possible value by the drive. So it is helpful to add a few 
+kbytes/sec just in case the drive has rounding problems.
+(mmc5r03c.pdf 6.37)
+
+Before writing can occur, a Write Parameters mode page 05h has to be composed
+and transmitted via 55h MODE SELECT. Mode page 05h describes several burn
+parameters:
+ BUFE             Buffer Underrun protection      0=off, 1=on
+ Test Write       -dummy mode for writing         0=off, 1=on
+ Write Type       Packet/TAO/SAO/RAW              01h = TAO
+ Multi-session    Wether to keep appendable       00b = finalize
+                                                  11b = keep appendable
+ Track Mode       Describes frame type            4 for data , 0 for audio
+ Data Block Type  Layout of payload blocks        8 for 2048 byte data blocks
+                                                  0 for 2352 byte audio blocks
+ Audio Pause Length                               150 = 2 seconds
+Any other parameters may be set to 0.
+Mode page data as of MMC-5 table 644 are preceded by a Mode Parameter Header
+as of SPC-3 table 240. This 8-byte header may be filled with zeros.
+(mmc5r03c.pdf 7.5.4 The Mode Page, 4.2.3.4 Table 17 CONTROL = Track Mode)
+(spc3r23.pdf 6.8 MODE SELECT, 7.4.3 Mode parameter header formats)
+
+
+Writing has to begin at the address returned by 52h READ TRACK INFORMATION
+with Address/Number Type set to 01b and Logical Block Address/Track/Session
+Number set to FFh. The Next Writeable Address as of table 500 is the number
+to start writing with.
+(mmc5r03c.pdf 6.27 )
+
+Writing is performed by one or more 2Ah WRITE transactions with the Logical
+Block Address counted up from the initial number in sync with the number of
+blocks written. I.e the Transfer Length of the previous 2Ah WRITE has to be
+added to the Logical Block Address for the next 2Ah WRITE. Only full blocks
+can be written.
+(mmc5r03c.pdf, 6.44)
+When writing is done, it is mandatory to force the drive's buffer to media by
+35h SYNCHRONIZE CACHE.
+(mmc5r03c.pdf, 6.41)
+
+A track must at least contain 300 payload blocks: 4 seconds of audio or
+600 KiB of data.
+(mmc5r03c.pdf 6.3.3.1.2)
+
+The track has to be closed by 5Bh CLOSE TRACK SESSION Close Function 001b.
+Older MMC specifies a valid Logical Track Number FFh to depict the open track.
+MMC-5 is quite silent about this. FFh works for my drives.
+(mmc5r03c.pdf 6.3.3.1.2)
+
+After that, a new track may be written beginning with sending the mode page 05h
+again. It is not tested wether 05h can be omitted if Track Mode and Data Block
+Type are the same as with the previous track.
+The new track will be added to the session which was opened by the first track.
+
+After the last track of a session, 5Bh CLOSE TRACK SESSION Close Function 010b
+with Logical Track Number 0 closes the session. It depends on the Multi-Session
+value in mode page 05h wether the disc is finalized or stays appendable.
+(mmc5r03c.pdf 6.3.3.1.3)
+
+
+-------------------------------------------------------------------------------
+Obtaining CD multi-session info for extending ISO-9660 filesystems :
+
+Program mkisofs expects two numbers with its option -C which describe the
+situation on an appendable CD which already contains a ISO-9660 filesystem
+in the first track of the last session.
+
+The first number is the Logical Block Address of that track containing the
+existing ISO-9660 filesystem image. This number is needed for mkisofs option
+-M to connect to the existing image. The new image will refer to files in
+the previously existing image. mkisofs option -M needs read access to the
+CD or a blockwise copy of it on hard disk. 
+The number is gained by 43h READ TOC/PMA/ATIP.
+(mmc5r03c.pdf 6.26)
+Untested is Format 0001b which in table 478 promises quick access via
+Start Address Of First Track In Last Session.
+(mmc5r03c.pdf 6.26.2.5 table 478, 6.26.3.3.1)
+libburn gets the number from its Table Of Content model which is obtained
+by 43h READ TOC/PMA/ATIP, Format 0010b. See below.
+
+The second number is an exact prediction of the Logical Block Address of the
+new track which will contain the newly generated ISO-9660 image.
+Even without mkisofs option -M this second number is still needed to make the
+inner block address pointers of the image match the Logical Block Addresses
+on CD. For that one may inquire 52h READ TRACK INFORMATION with
+Address/Number Type set to 01b and Logical Block Address/Track/Session
+Number set to FFh. The Next Writeable Address as of table 500 is the number
+to use.
+(mmc5r03c.pdf 6.27 )
+
+
+-------------------------------------------------------------------------------
+Obtaining a Table Of Content from CD :
+
+The structure of a CD is comprised of sessions. Each session contains one or
+more tracks and is followed by a lead-out. A track has an address and a length.
+
+Table of content information is gained by 43h READ TOC/PMA/ATIP, Format 0010b.
+(mmc5r03c.pdf 6.26.2.5 table 478)
+
+The number of sessions is given by Last Complete Session Number.
+The number of TOC Track descriptors is: (TOC Data Length - 2)/11 . 
+
+Each TOC Track Descriptor contains a Session Number.
+
+If POINT is >= 1 and <= 99 (63h) then the descriptor is about the track of
+which POINT tells the number.
+The start address of this track can be read from PMIN, PSEC, PFRAME where
+it is encoded in MSF format:
+blocks = frames - 150, 75 frames = 1 sec , 60 sec = 1 min.
+The length of the track is given by MIN,SEC,FRAME in the same format.
+
+If POINT = A0h then the descriptor tells in PMIN the first track number of its
+session.
+POINT = A1h tells in PMIN the last track number of its session.
+POINT = A2h describes in PMIN, PSEC, PFRAME the lead-out of a session, i.e the
+first address after the session's end. (Next writeable address typically is
+lead-out + 11400 after the first session, lead-out + 6900 after further
+sessions.)
+POINT = B0h tells in MIN,SEC,FRAME this next writeable address or FFh,FFh,FFh
+for finalized disc.
+(mmc5r03c.pdf 6.26.3.4 table 489, 4.2.3.7 Mode-1 Q, Mode-5 Q)
+
+
+In libburn the address of the first track in the last session is obtained from
+the last session's POINT = A0h and from the track descriptor with the POINT
+value matching the PMIN value of the A0h descriptor.
+Untested is wether POINT = B0h and 52h READ TRACK INFORMATION are always in
+sync. libburn uses the info provided by 52h READ TRACK INFORMATION.

+
+Recognition of media type and state (blank, appendable, finalized) is as
+described in the TAO Multi-Session CD Cookbook. See there.
+
+The MMC specs do not give much hint about the combination of SAO and
+multi-session. My drives refused not only on a few experiments which i did
+in libburn but also failed with cdrecord -sao on an appendable CD.
+So for now only blank CD seem to be suitable for SAO writing.  
+
+Different from TAO mode, the whole session layout is announced to the drive by
+sending a Cue Sheet. This implies that the sizes of the tracks have to be known
+in advance, which is a heavy drawback when dealing with track data sources like
+stdin, named pipes or sockets.
+Nevertheless, SAO seems to be best writing mode for audio purposes, as our
+audio expert Lorenzo Taylor found out.
+
+A SAO session in libburn may either consist entirely of audio tracks or
+entirely of data tracks. For mixed sessions, only TAO is usable yet.
+
+- Composing a SAO CD Cue Sheet (either audio or data, but not mixed)
+- Writing the prepared SAO CD session
+- What is known about mixed mode sessions
+
+
+-------------------------------------------------------------------------------
+Composing a Cue Sheet (either audio or data, but not mixed) :
+
+The Cue Sheet will get submitted to the drive by 5Dh SEND CUE SHEET.
+Each entry of the sheet is of 8 bytes size. Its fields are named
+CTL|ADR, TNO, INDEX, DATA FORM, SCMS, MIN, SEC, FRAME .
+(mmc5r03c.pdf 6.33)
+
+CTL is 40h for data and 00h for audio.
+(mmc5r03c.pdf 6.33.3.4)
+ADR is always 01h.
+TNO is the track number (1 to 99).
+INDEX is a subaddress within tracks. This recipe uses only INDEX 01h within
+tracks.
+(mmc5r03c.pdf 4.2.3.5.2)
+DATA FORM is 00h for audio payload , 10h for data. (01h for audio pause is not
+used in libburn). 
+(mmc5r03c.pdf 6.33.3.11 CD-DA Data Form, 6.33.3.12 CD-ROM mode 1 Form)
+SCMS is always 00h.
+MIN, SEC, FRAME give the MSF address where the described data entity starts.
+LBA = frames - 150, 75 frames = 1 sec , 60 sec = 1 min.
+This address must increase from entry to entry (or at least stay equal).
+
+
+The first entry describes the Lead-in. 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. (With libburn CTL is as of the last track.)
+
+
+-------------------------------------------------------------------------------
+Writing the prepared session :
+
+Speed may be set by BBh SET CD SPEED parameter Drive Write Speed. Note that
+kbytes/sec means 1000 bytes/sec and not 1024/sec. Rotational control should
+be set to 00b. 1x CD speed is 176.4 kbytes/sec. Speed is usually set to the
+next lower possible value by the drive. So it is helpful to add a few
+kbytes/sec just in case the drive has rounding problems.
+(mmc5r03c.pdf 6.37)
+
+A Write Parameters mode page 05h has to be composed and transmitted via
+55h MODE SELECT. This page describes the following parameters:
+ BUFE             Buffer Underrun protection      0=off, 1=on
+ Test Write       -dummy mode for writing         0=off, 1=on

+
+The Cue Sheet is submitted to the drive by 5Dh SEND CUE SHEET. Cue Sheet Size
+is 8 times the number of entries.
+(mmc5r03c.pdf 6.33)
+
+Writing is performed by multiple 2Ah WRITE transactions with the Logical
+Block Address counted up from the initial number in sync with the number of
+blocks written. I.e the Transfer Length of the previous 2Ah WRITE has to be
+added to the Logical Block Address for the next 2Ah WRITE. Only full blocks
+can be written.
+(mmc5r03c.pdf, 6.44)
+Writing begins at LBA -150 which is to be transmitted as 4-byte, Big-endian,
+two's-complement. E.g:  -150 = FFh FFh FFh 6Ah. This is the natural form found
+with about any 32-bit processor, so only the endianness has to be taken into
+respect when converting a 32-bit integer into a LBA for command 2Ah WRITE.
+
+
+At first the mandatory pause preceding the first track has to be written as
+150 blocks of the matching sector size: 2048 for data, 2352 for audio.
+By this, the LBA increases from -150 to 0.
+
+Next the tracks' payload is sent. For each track exactly the number of blocks
+has to be transmitted as is announced in the Cue Sheet by the difference
+of the track's own start address and the start address of the next entry in
+the Cue Sheet. After each write the LBA for the next write has to be increased
+by the number of blocks transmitted. Just like with TAO writing.
+
+There is no separator between the tracks of a pure mode SAO session.
+(If the session was mixed mode, there would be extended Pre-gaps and Post-gaps
+between data mode tracks and audio mode tracks.)
+(libburn sends its own buffer to the drive at the end of each track but does
+not sync the drive's chache. It is unclear wether this separation of tracks
+on the level of 2Ah WRITE is necessary with a pure mode session. It does not
+harm in any case and would probably be unavoidable if audio and data tracks
+were mixed.)
+
+When writing of all tracks is done, it is mandatory to force the drive's buffer
+to media by 35h SYNCHRONIZE CACHE.
+(mmc5r03c.pdf, 6.41)
+
+No further finalization is necessary. (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.

+
+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 or DVD-RW
+- Unformatted DVD+RW
+- Partly formatted DVD+RW
+- Unformatted DVD-RW
+- Partly formatted DVD-RW
+- Intermediate state DVD-RW
+
+
+-------------------------------------------------------------------------------
+Overwriting in general :
+
+Depending on media type, some kind of formatting has to have happened before
+data can be written. Formatting may happen separately from writing or
+simultaneously. See the particular recipes below.
+
+No Write Parameters mode page 05h is to be sent. Speed can be influenced by
+B6h SET STREAMING , speed capabilities can be inquired by ACh GET PERFORMANCE.
+It is advised to set only speeds and sizes which are returned by ACh.
+(mmc5r03c.pdf 6.39 SET STREAMING, 6.8 GET PERFORMANCE)
+Optimal performance is promised without any speed setting. But my experiments
+showed that SET STREAMING values persist after media change.
+
+In the formatted area of the media, coarse random access is possible.
+For DVD-RAM and DVD+RW write addresses and data size need to be aligned
+to 2 KiB. For DVD-RW alignment has to be 32 KiB. Within these limitations
+the write address is at the discretion of the sending program.
+Just use 2Ah WRITE to send data.
+(mmc5r03c.pdf, 6.44)
+When writing is done, it is mandatory to force the drive's buffer to media by
+35h SYNCHRONIZE CACHE.
+(mmc5r03c.pdf, 6.41)
+
+The size of the formatted area can be inquired by 23h READ FORMAT CAPACITIES.
+The Number Of Blocks value in the Current/Maximum Capacity Descriptor gives
+this size in 2 KiB blocks. But this is true only if Descriptor Type is 10b
+("Formatted Media").
+(mmc5r03c.pdf, 6.24.3.2.1, 6.24.3.2.3)
+
+Not yet formatted areas may be completely forbidden or they may be allowed for
+sequential writing (DVD-RW Intermediate state) or they may be allowed for
+random access only after the necessary waiting time for formatting to reach
+the desired address (DVD+RW with background formatting active).
+
+Already written areas can be overwritten without special precaution.
+Blanking a DVD-RW actually destroys its formatting.
+
+
+Most of the concepts usually expressed in Write Parameters mode page 05h do not
+apply to the recipes here: Test-Write, Buffer Underrun protection,
+Multi-session, Write Type, Block Type, Track Mode, ...
+There are hints for multi-session formats with DVD-RW but both of my drives
+do not offer "Add Session" Format Types 12h or 14h.
+(mmc5r03c.pdf 6.5.4.2.7 , 6.5.4.2.9)
+
+
+Caution: Drive and media compatibility seems still to be quite an adventure.
+If you experience problems, especially problems with readability, then try
+different drives and media brands. Failure does not necessarily mean that the
+software did anything wrong.
+
+
+-------------------------------------------------------------------------------
+DVD-RAM, fully formatted DVD+RW or DVD-RW :
+
+Full format is the natural state of DVD-RAM. 
+
+DVD+RW reaches this state if Background Formatting is allowed to finish without
+being stopped by 5Bh CLOSE TRACK SESSION.
+(mmc5r03c.pdf, 6.5 FORMAT UNIT, 6.5.4.2.14 Format Type = 26h)
+The formatting state of a DVD+RW may be inquired by 51h READ DISC INFORMATION
+requesting Data Type 000b "Standard Disc Information". In the reply,
+BG Format 3 indicates fully formatted media.
+(mmc5r03c.pdf 6.22.3.1.13)
+
+DVD-RW reaches this state either by Format Type 00h (or 10h) with maximum
+size given as Number Of Blocks, or by writing sequentially until the disc is
+completely full into an intermediate session opened by format 15h resp. 13h.
+(mmc5r03c.pdf, 6.5 FORMAT UNIT, 6.5.4.2.1, 6.5.4.2.10, 6.5.4.2.8)
+A fully formatted DVD-RW can be recognized by 23h READ FORMAT CAPACITIES. The
+Descriptor Type of the Current/Maximum Capacity Descriptor is 10b ("Formatted
+Media") and 0 blocks are offered with Format Types 13h or 11h.
+(mmc5r03c.pdf, 6.24.3.2.1, 6.24.3.3)
+See also discussion of unformatted or partially formatted DVD-RW below.
+
+
+In fully formatted state there is no need for any formatting before writing nor
+for any finalizing other than forcing the drive's buffer to media by
+35h SYNCHRONIZE CACHE (which is mandatory for writing, anyway).
+(mmc5r03c.pdf, 6.41)
+
+(It seems to do no harm to send to DVD+RW or DVD-RW a 5Bh CLOSE TRACK SESSION
+with Close Function 010b despite there is no session open in this scenario.)
+
+
+-------------------------------------------------------------------------------
+Unformatted DVD+RW
+
+This is the state of previously unused DVD+RW media.
+
+The formatting state of a DVD+RW may be inquired by 51h READ DISC INFORMATION
+requiring Data Type 000b "Standard Disc Information".
+In the reply, BG Format 0 indicates unformatted media (or unsuitable media).
+(mmc5r03c.pdf 6.22.3.1.13)
+
+Formatting has to be started by command 04h FORMAT UNIT, Format Type 26h.
+Different from other format types, 26h allows to send a fantasy size of
+0xffffffff blocks and does not require the caller to know the exact maximum
+size offered with that format.
+(mmc5r03c.pdf, 6.5 FORMAT UNIT, 6.5.4.2.14 Format Type = 26h)
+
+As its name suggests, one has not to wait for background formatting to end
+but may very soon start writing as on formatted media. Random access to
+yet unformatted areas can last long, though.
+
+If backup formatting has been started at the beginning of the session, then
+it may get stopped after the final cache sync by 5Bh CLOSE TRACK SESSION
+with Close Function 010b. 
+(mmc5r03c.pdf 6.3.3.6)
+
+Formatting of DVD+RW is called "de-icing" because unformatted areas offer
+no hold for random access addressing and are thus slippery like ice. One can
+also see a color change from shiny unformatted to more dull formatted media.
+
+
+-------------------------------------------------------------------------------
+Partly formatted DVD+RW :
+
+This state is achieved by stopping background formatting before the media
+was completely formmatted. 
+
+The formatting state of a DVD+RW is obtained by 51h READ DISC INFORMATION
+requiring Data Type 000b "Standard Disc Information".
+In the reply, BG Format 1 indicates partly formatted media.
+(mmc5r03c.pdf 6.22.3.1.13)
+
+If the data of the session surely fit into the formatted area, then it would
+be unnecessary to restart background formatting.
+But in order to make the DVD+RW surely accept its maximum number of bytes,
+formatting may be restarted by command 04h FORMAT UNIT, Format Type 26h,
+with the Restart bit set and Number of Blocks set to 0xffffffff.
+(mmc5r03c.pdf, 6.5 FORMAT UNIT, 6.5.4.2.14 Format Type = 26h)
+
+From then on, the same rules apply as for previously unformatted DVD+RW.
+
+
+-------------------------------------------------------------------------------
+Unformatted DVD-RW (media profile is 0014h) :
+
+This state is present with previously unused media. It is also present with
+media blanked by programs cdrecord, wodim or dvd+rw-format and with media which
+were sequentially written from blank state.
+Profile transition from formatted 0013h to unformatted 0014h is done by
+A1h BLANK.
+(mmc5r03c.pdf, 6.2)
+Experiments on my drives indicate that only Blanking Type 000b "Blank the disc"
+achieves neat media. Media blanked via type 001b offer no feature 0021h and
+stall cdrecord or libburn already when those media get examined. growisofs can
+burn them - but only via DAO (feature 002Fh which prescribes Write Type 2).
+(mmc5r03c.pdf 5.3.11, 5.3.25)
+
+For becoming overwriteable such media need to be treated by command 04h FORMAT
+UNIT.
+(mmc5r03c.pdf, 6.5)
+The Format Type has to be chosen from the list replied by 23h READ FORMAT
+CAPACITIES. Suitable are Format Types 00h, 10h, 15h.
+(mmc5r03c.pdf 6.24)
+
+Format Types 00h and 10h provide a writeable area of a size given by Number of
+Blocks. Type 00h seems to be the most traditional and complete one. It needs
+no closing of a session at the end of writing.
+The Number Of Blocks may be at most the value reported by 23h READ FORMAT
+CAPACITIES in the entry for the desired format type. Full format is achieved
+by sending exactly the reported value.
+(mmc5r03c.pdf, 6.5.4.2.1 Format Type = 00h, 6.5.4.2.5 Format Type = 10h)
+
+Format Type 15h provides a writeable area of given size too, but this area can
+be expanded by sequential writing and afterwards marked as overwriteable by
+closing the session. It is even allowed to format with size 0 and to leave
+the size claim entirely to a sequential write process beginning at LBA 0.
+(mmc5r03c.pdf, 6.5.4.2.10 Format Type = 15h)
+When writing is done and cache is synced, one should send 5Bh CLOSE TRACK
+SESSION with Close Function 010b in order to bring the session out of
+Intermediate state. 
+(mmc5r03c.pdf 6.3.3.2.3)
+If not written up to the last 32 KiB block, the DVD-RW is only partly formatted
+after that.
+
+
+-------------------------------------------------------------------------------
+Partly formatted DVD-RW (media profile is 0013h) :
+
+This state is achieved by formatting a DVD-RW with a number of blocks which
+is less than offered for the Format Type by the drive's reply to 23h READ
+FORMAT CAPACITIES. If the media was most recently formatted by Format Types
+015h or 013h then it must have got written some bytes and afterwards treated
+by 5Bh CLOSE TRACK SESSION, 010b in order to be partly formatted.
+(mmc5r03c.pdf 6.3.3.2.3 CLOSE TRACK SESSION 010b, 6.24 READ FORMAT CAPACITIES)
+Elsewise the media is in Intermediate state. See below.
+
+A partly formatted DVD-RW can be recognized by 23h READ FORMAT CAPACITIES. The
+Descriptor Type of the Current/Maximum Capacity Descriptor is 10b ("Formatted
+Media") and the Number Of Blocks with formats 00h, 10h or 15h is larger than the
+currently formatted size, resp. more than 0 blocks are offered with Format
+Types 13h or 11h.
+(mmc5r03c.pdf, 6.24.3.2.1, 6.24.3.3)
+
+If the data of the session surely fit into the formatted area, then it would
+be unnecessary to do any further formatting.
+But in order to make the DVD-RW surely accept its maximum number of bytes,
+partial formatting may be expanded by command 04h FORMAT UNIT, Format Type 13h,
+which is supposed to be offered by the drive in this state. This brings the
+session again into Intermediate state and thus allows expansion by sequential
+writing. As with Format Type 15h it is ok to set Number Of Blocks to 0, so that
+no fixed size formatting work is done and writing can begin soon after.
+(mmc5r03c.pdf, 6.5.4.2.8 Format Type = 13h)
+
+When writing is done and cache is synced, one should send 5Bh CLOSE TRACK
+SESSION with Close Function 010b in order to bring the session out of
+Intermediate state. 
+(mmc5r03c.pdf 6.3.3.2.3)
+If not written up to the last 32 KiB block, the DVD-RW is only partly formatted
+after that.
+
+Format Type 13h has been tested only with expanding sessions formatted by 15h.
+Nevertheless it is offered with sessions from 00h and 10h, too.
+According to the specs, Format Type 11h would expand a session by a fixed
+size. This has not been tested yet because it is less appealing than 13h.
+(mmc5r03c.pdf, 6.5.4.2.6 Format Type = 11h)
+
+
+-------------------------------------------------------------------------------
+Intermediate state DVD-RW (media profile is 0013h) :
+
+This state is achieved by formatting a DVD-RW with Format Type 15h or 13h
+without subsequentially writing data and sending 5Bh CLOSE TRACK SESSION
+with Close Function 010b.
+Such media behave very unpleasing with my DVD-ROM drive under Linux 2.4 ide-cd.
+One should therefore better avoid to release media in this state.
+
+This state can be recognized by 23h READ FORMAT CAPACITIES. The Descriptor Type
+of the Current/Maximum Capacity Descriptor is 11b ("Unknown Capacity") and
+no formats 13h or 11h are offered.
+(mmc5r03c.pdf, 6.24.3.2.1, 6.24.3.3)
+
+One may treat such media as if Format Type 15h or 13h had been freshly applied.
+I.e. sequential writing from LBA 0. After cache sync bring the session out
+of Intermediate state by 5Bh CLOSE TRACK SESSION with Close Function 010b.

+DVD-RW Restricted Overwrite    0013h
+DVD-RW Sequential Recording    0014h
+
+There are two approaches for writing to sequential DVD-R[W]: DAO and
+Incremental. Not all media and drives offer Incremental which allows 
+multi-session as with CD media and does not demand a predicted track size.
+DAO seems to be the older method. It allows only one single session and

+-------------------------------------------------------------------------------
+About overwriteable, blank, appendable and finalized DVD-R[W] media :
+
+DVD-RW can be either in formatted state Restricted Overwrite or in unformatted
+state Sequential Recording. Sequential media can be either blank, appendable
+or finalized.
+
+Only blank and appendable media are sequentially writeable. For overwriteable
+DVD-RW see the Overwriteable DVD Cookbook.
+
+Overwriteable DVD-RW can be detected by their profile number 0013h in contrast
+to profile number 0014h for sequential DVD-RW.
+The status of sequential media can be inquired like with CD by 51h READ DISC
+INFORMATION requesting Data Type 000b Standard Disc Information, where reply
+value Disc Status indicates:
+ 00b   blank
+ 01b   appendable  
+ 10b   finalized
+ 11b   others (unsuitable for this recipe)
+(mmc5r03c.pdf 6.22.3.1.4)
+
+Finalized, appendable or overwriteable DVD-RW can be brought into blank
+sequential state by command A1h BLANK with blanking type 000b "Blank the disc".
+See TAO Multi-Session CD Cookbook for details about blanking.
+
+After minimal blanking (type 001b) DVD-RW my two drives do not offer the
+Incremental Streaming feature 0021h the media any more. Full blanking (000b)
+brings back this feature.
+(mmc5r03c.pdf 6.2)
+
+
+-------------------------------------------------------------------------------
+Incremental writing :
+
+Incremental writing allows to produce multi-session DVDs. It is indicated
+by feature 0021h being marked current in the reply of 46h GET CONFIGURATION.
+growisofs inquires 0021h by setting Starting Feature Number to 0x21 and
+Allocation Length to 16 in order to get only this one. The feature descriptor
+begins at byte 8 of the reply. Its availability is indicated by the Current
+Bit. libburn obtains the full feature list for this and other info.

+growisofs fetches a mode page 05h template by MODE SENSE and inserts its own

+growisofs takes the Track Mode from 52h READ TRACK INFORMATION, Address/Number
+Type 1, Track 1, Track Information Block byte 5 & 0xf.
+(mmc5r03.pdf 6.27)
+The specs predict that this will be Track Mode 4 (6.27.3.8) and also state that
+default is 5 (7.5.4.12). 4 means: uninterrupted, do not copy. 5 means
+increment, do not copy.
+[*2:]
+8 means: 2048 byte data blocks. growisofs sets this value if Data Mode from
+above 52h READ TRACK INFORMATION is 1 or Fh, which is predicted by the specs
+to be always true.
+(mmc5r03.pdf 6.27.3.10)
+[*3:]
+growisofs (transport.hxx) sets Link Size to 16 for profiles 0011h and 0014h.
+libburn now records the first link size from feature 0021h in its burn_drive
+structure. If another link size item is 16, then 16 is used.
+[*4:]
+growisofs takes Packet Size from 52h. Specs predict it will be 16 (= 32 kB).
+(mmc5r03.pdf 7.5.4.16)
+
+The writing process is much like in "Writing a session to CD in TAO mode" :
+Next Writeable Address is fetched from the reply of 52h READ TRACK INFORMATION.
+libburn writes full 32 kB buffers via 2Ah WRITE.
+(mmc5r03c.pdf, 6.27 READ TRACK INFORMATION, 6.44 WRITE)
+When writing is done, it is mandatory to force the drive's buffer to media by
+35h SYNCHRONIZE CACHE.
+(mmc5r03c.pdf, 6.41)
+
+The track has to be closed by 5Bh CLOSE TRACK SESSION Close Function 001b.
+growisofs uses the logical track number for that and not FFh like libburn
+does with TAO CD. So libburn obtains the Last Track Number in Last Session
+from the reply of  51h READ DISC INFORMATION requesting Data Type 000b
+"Standard Disc Information".
+(mmc5r03c.pdf 6.3.3.2.2 CLOSE TRACK, 6.22.3.1.)
+
+Multiple tracks are permissible in a single session. After all of them have
+been written, 5Bh CLOSE TRACK SESSION Close Function 010b with Logical Track

+(mmc5r03c.pdf 5.3.25)
+Experiments with growisofs showed that the track size needs to be predicted
+and may not be exceeded during the write process. (growisofs ran into SCSI

+(mmc5r03.pdf 6.27)
+[*2:]
+8 means: 2048 byte data blocks. growisofs sets this value if Data Mode from
+above 52h READ TRACK INFORMATION is 1 or Fh, which is predicted by the specs
+to be always true. (If not: growisofs aborts.)
+(mmc5r03.pdf 6.27.3.10)
+[*3:]
+Link Size, Packet Size and their companions only apply to Write Type 00h.
+
+The session layout must be described by 53h RESERVE TRACK, RMZ=ARSV=0.
+Reservation size should better already be aligned to 32 KiB. It has not been
+tested yet, what happens if not enough data get written.
+(mmc5r03c.pdf 6.31)
+
+Next Writeable Address is fetched from the reply of 52h READ TRACK INFORMATION.
+The reply is supposed to be 0. libburn writes full 32 kB buffers via 2Ah WRITE.
+(mmc5r03c.pdf, 6.27 READ TRACK INFORMATION, 6.44 WRITE)
+If the track source delivers less than the announced size then libburn pads up
+by zeros.
+When writing is done, it is mandatory to force the drive's buffer to media by
+35h SYNCHRONIZE CACHE.
+(mmc5r03c.pdf, 6.41)
+
+No further finalization is necessary. (I.e. no 5Bh CLOSE TRACK SESSION.)
+
+
+-------------------------------------------------------------------------------
+Obtaining DVD-R[W] multi-session info for extending ISO-9660 filesystems :
+
+Like with CD it is necessary to obtain the two numbers for mkisofs option -C
+in order to prepare a ISO-9660 filesystem image which by its inner pointers
+matches the block addresses of the future location on media.
+These are the start address of the first track in the last complete session
+and the predicted start address of the track which will host the new image.
+See TAO Multi-Session CD Cookbook for some more info about mkisofs aspects.
+
+
+The first number may be gained by 43h READ TOC/PMA/ATIP Format 0001b which in
+table 478 promises quick access via Start Address Of First Track In Last
+Session.
+(mmc5r03c.pdf 6.26.2.5 table 478, 6.26.3.3.1)
+Regrettably the MMC-5 specs still define a useless reply for non-CD media
+which obviously stems from MMC-3 times when no multi-session was possible
+with non-CD.
+(mmc5r03c.pdf 6.26.3.3.3)
+Both my drives do give a useful reply with the correct number for appendable
+DVD-RW. But not being backed by the specs this method appears unappealing .
+
+Another approach would be a formatted Table of Content, obtained by 43h READ
+TOC/PMA/ATIP Format 0000b. The specs do not totally outrule that this returns
+useful data with non-CD but they define a crippled TOC for multi-session.
+(mmc5r03c.pdf 6.26.3.2.4)
+My LG drive returns a more detailed TOC, my NEC drive stays with the rather
+suboptimal specs. So one would get different TOCs on different drives.
+Nevertheless, the MMC-5 compliant TOC would return the desired number in
+the Track Start address of the track with the highest number before AAh.
+
+Most stable seems the approach to obtain the desired number from the reply
+of 52h READ TRACK INFORMATION, Address/Number Type 01b. The field Logical Block
+Address/Track/Session has to bear the track number of the first track in the
+last complete session. To determine this number one has to determine the
+number of the last session and the number of the last track from 51h READ DISC
+INFORMATION and to iterate over the tracknumber by 52h READ TRACK INFORMATION
+until the first track with the desired session number appears and reveils
+its start address. 
+(mmc5r03c.pdf 6.22 51h DISC, 6.27 52h TRACK)
+This method is very near to fabricating an own TOC. So libburn does this 
+when inspecting the media. If the first number for -C is needed, libburn
+inquires its TOC model for the address of the first track in the last
+complete session. See below for a detailed description of TOC fabrication.
+
+
+The second -C number is the exact prediction of future track start address. It
+is gained like with CD by 52h READ TRACK INFORMATION Type 01b. Different from
+CD one may not use track number FFh but has to use the Last Track in Last
+Session from 51h READ DISC INFORMATION. 
+(mmc5r03c.pdf 6.22 51h DISC, 6.27 52h TRACK)
+
+
+-------------------------------------------------------------------------------
+Obtaining a Table Of Content from DVD-R[W] :
+
+The raw TOC entries from 43h READ TOC/PMA/ATIP Format 0010b as described with
+CD media are not available with non-CD.
+There is a Format 0000b "Formatted TOC" but this is with non-CD a fictional
+information much at the discretion of the drive. Two drives with the same disc
+may well return different Formatted TOC. They are supposed to be consistent
+only about the last complete session and even there the MMC-5 specification
+6.26.3.2.5 seems to prescribe a structure which does not match the true
+structure of incremental writing to sequential DVD-R[W].
+(mmc5r03c.pdf 6.26.3.2)
+So i prefer not to use this method of getting a TOC.
+
+
+The alternative is to produce an own TOC from information gained by 51h READ
+DISC INFORMATION and by 52h READ TRACK INFORMATION which reveil a CD-like
+structure of sessions and 1:n related tracks.
+
+51h READ DISC INFORMATION Data Type 000b, fields Number of Sessions (Least
+Significant Byte) and Number of Sessions (Most Significant Byte) give the
+number of sessions. The last complete session number of an appendable disc
+is one less because there is an incomplete session at its end. libburn only
+records complete sessions in its TOC model.
+libburn uses Last Track in Last Session as a hint for the range of track
+numbers.
+(mmc5r03c.pdf 6.22)
+
+Next step is to iterate from 1 up to the last track number and to obtain
+the according track info by 52h READ TRACK INFORMATION. Each track tells its
+Session Number (LSB at byte 2, MSB at 33), its Logical Track Start Address,
+its Logical Track Size, and much more which is not needed for a fake CD TOC.
+One may analyze the track info more finely but for this special purpose
+it is enough to discard the tracks which do not belong to complete sessions.
+(mmc5r03c.pdf 6.27)
+
+At the end of each session libburn inserts fake leadout entries into its TOC
+model. Their start address is computed from the start and size of the last
+track of the session.

+
+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.
+
+

+/**                               Overview 
+  
+  telltoc is a minimal demo application for the library libburn as provided
+  on  http://libburnia.pykix.org . It can list the available devices, can
+  display some drive properties, the type of media, eventual table of content
+  and multisession info for mkisofs option -C . 
+  It's main purpose, nevertheless, is to show you how to use libburn and also
+  to serve the libburn team as reference application. telltoc.c does indeed
+  define the standard way how above gestures can be implemented and stay upward
+  compatible for a good while.
+  
+  Before you can do anything, you have to initialize libburn by
+     burn_initialize()
+  as it is done in main() at the end of this file. Then you aquire a
+  drive in an appropriate way conforming to the API. The two main
+  approaches are shown here in application functions:
+     telltoc_aquire_by_adr()       demonstrates usage as of cdrecord traditions
+     telltoc_aquire_by_driveno()   demonstrates a scan-and-choose approach
+  With that aquired drive you can call
+     telltoc_media()   prints some information about the media in a drive
+     telltoc_toc()     prints a table of content (if there is content)
+     telltoc_msinfo()  prints parameters for mkisofs option -C
+  When everything is done, main() releases the drive and shuts down libburn:
+     burn_drive_release();
+     burn_finish()
