-                              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.
-

-
-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.

-.SH NAME
-cdrskin \- burns preformatted data to CD-R or CD-RW 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. 
-You don't need to be root to use it.
-.PP
-.B Overview of features:
-.br
-Blanking of CD-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 (follow-up sessions in TAO only).
-.br
-Bus scan, burnfree, speed options, retrieving media info, padding, fifo.
-.br
-See section EXAMPLES at the end of this text.
-.PP
-.B Known deficiencies:
-.br
-No DVD support yet.
-.PP
-.B Track recording model:
-.br
-The input-output entities which get processed are called tracks.
-A track 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 source and the state of the output media.
-.PP
-There can be more than one track burned by a single run of cdrskin.
-CDs 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.
-.br
-If not explicitely option -audio is given, then any track is burned as 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
-data 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 with CD, 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.
-.br
-CD-RW media can be blanked to make them re-usable for another
-round of overwriting. 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.
-.br
-.SH OPTIONS
-.TP
-.BI \-\-help
-Show non-cdrecord compatible options.
-.TP
-.BI \-help
-Show cdrecord compatible options.
-.TP
-.BI \-version
-Print cdrskin id line, compatibility lure line, libburn version, cdrskin
-version, version timestamp, build timestamp (if available), and then exit.
-.PP
-Alphabetical list of options which are intended to be compatible with
-original cdrecord by Joerg Schilling:
-.TP
-.BI \-atip
-Retrieve some info about media state. With CD-RW print "Is erasable".
-.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. 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 automatically. Same is done for suffix .au and SUN Audio.
-.TP 
-.BI blank= type
-Blank a CD-RW disc. 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 the entire disk.
-.TP
-fast
-Minimally blank the entire disk.
-.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 disk in Session 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
-Sets the (pseudo-)SCSI address of the drive to use. Valid are at least the
-X,Y,Z addresses listed with option -scanbus, ATA:X,Y,Z addresses listed with
-options dev=ATA -scanbus, the device file addresses listed with
-option --devices , 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 on multi-drive systems.
-.br
-The special target "help" lists hints about available addressing formats.
-Be aware that option --old_pseudo_scsi_adr changes the meaning of 
-Bus,Target,Lun addresses.
-.TP
-.BI driveropts= opt
-Set "driveropts=burnfree" to enable the drive's eventual protection mechanism
-against temporary lack of source data (i.e. buffer underrun).
-It is not an error to do this with a drive that has no such capabilities.
-.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 drive
-in a particular write mode. Blanking is prevented reliably, though.
-.TP
-.BI \-eject
-Eject the disk 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
-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 \-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 appendable after the current session has been written.
-Without it the disk gets closed and may not be written any more  - unless it
-is a CD-RW and gets blanked which causes loss of its content.
-.br
-The following sessions can only be written in -tao mode.
-.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 disk 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 disk in Session At Once mode. This mode is able to put several audio
-tracks on CD without producing audible gaps between them. It 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=.
-.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 kB/s. 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 disk in Track At Once (TAO) mode. This mode 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 CD which
-already hold data.
-.TP
-.BI \-toc
-Print the table of content (TOC) which describes the tracks recorded on CD.
-The output contains all info from option -atip plus lines which begin with
-"track:  " followed by 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 data tracks hold 2048 bytes each.
-.RS
-.TP
-Example. Retrieve an afio archive from track number 2:
-.br
-tracknumber=2
-.br
-lba=$(cdrskin dev=/dev/cdrom -toc 2>&1 | \\
-.br
-grep '^track:  [ 0-9][0-9]' | \\
-.br
-tail +"$tracknumber" | head -1 | \\
-.br
-awk '{ print $4}' )
-.br
-dd if=/dev/cdrom bs=2048 skip="$lba" | \\
-.br
-afio -t - | less
-.RE
-.TP
-.BI tsize= size
-Announces the exact size of the next track source. This is necessary with any
-write mode other than -tao if the track source is not a regular disk file, but
-e.g. "-" (standard input) or a named pipe.
-About size specifiers, see option fs=.
-.br
-If the track source does not deliver the predicted amount of bytes, the
-remainder of the track is padded with zeros. This is not considered an error.
-If on the other hand the track source delivers more than the announced bytes
-then the track on CD 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 program abort triggered by an 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 of cdrecord-2.01.
-.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 drives. In order to get
-listed a drive has to offer rw-permission for the cdrskin user and it may
-not be busy.
-Busy drives are reported as "SORRY" messages on standard error.
-.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).
-Normal users might not see all drives unless the superuser enabled access
-by chmod o+rw
-after using cdrskin --devices to get an overview of the situation.
-That's why current rw-Permissions are listed.
-.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
-has to be enabled by driveropts=burnfree.
-.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 \--single_track
-Accept only the last argument of the command line as track source address.
-.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. 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.
-.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.
-This is the fallback from bad old times when cdrskin was unable to burn
-in mode -tao.

-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.

-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: Linux SCSI Generic (sg)
-
-
-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.
-
-
-Porting hints are marked by the text "PORTING:".
-Send feedback to libburn-hackers@pykix.org .
-
-Hint: You should also look into sg-freebsd-port.c, which is a younger and
-      in some aspects more straightforward implementation of this interface.

-/**                               Overview 
-  
-  telltoc is a minimal demo application for the library libburn as provided
-  on  http://libburn.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()
