/* test/libburner.c , API illustration of burning data or audio tracks to CD */
/* Copyright (C) 2005 - 2010 Thomas Schmitt <scdbackup@gmx.net> */
/* Provided under GPL, see also "License and copyright aspects" at file end */
/** Overview
libburner is a minimal demo application for the library libburn as provided
on http://libburnia-project.org . It can list the available devices, can
blank a CD-RW or DVD-RW, can format DVD-RW and BD, can burn to CD-R,
CD-RW, DVD-R, DVD+R, DVD+R/DL, DVD+RW, DVD-RW, DVD-RAM, BD-R, BD-RE.
Not supported yet: DVD-R/DL.
It's main purpose, nevertheless, is to show you how to use libburn and also
to serve the libburnia team as reference application. libburner.c does indeed
define the standard way how above three 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()
and provide some signal and abort handling, e.g. by the builtin handler, by
burn_set_signal_handling()
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:
libburner_aquire_by_adr() demonstrates usage as of cdrecord traditions
libburner_aquire_by_driveno() demonstrates a scan-and-choose approach
With that aquired drive you can blank a CD-RW or DVD-RW
libburner_blank_disc()
or you can format a DVD-RW to profile "Restricted Overwrite" (needed once)
or an unused BD to default size with spare blocks
libburner_format()
With the aquired drive you can burn to CD, DVD, BD
libburner_payload()
When everything is done, main() releases the drive and shuts down libburn:
burn_drive_release();
burn_finish()
FreeBSD does not work well with the convenient synchronous signal handler. So
the waiting loops for blanking, formatting, and writing use the asynchronous
mode of the libburn signal handler. It will not shutdown the library and
abort the program, but rather tell the ongoing drive operation to stop as
soon as possible. After the loops and at the end of the program there is a
call to determine whether an abort happened:
burn_is_aborting()
Applications must use 64 bit off_t. E.g. by defining
#define _LARGEFILE_SOURCE
#define _FILE_OFFSET_BITS 64
or take special precautions to interface with the library by 64 bit integers
where libburn/libburn.h prescribes off_t.
This program gets fed with appropriate settings externally by libburn's
autotools generated build system.

/** Brings preformatted track images (ISO 9660, audio, ...) onto media.
To make sure a data image is fully readable on any Linux machine, this
function adds 300 kiB of padding to the (usualy single) track.
Audio tracks get padded to complete their last sector.
A fifo of 4 MB is installed between each track and its data source.
Each of the 4 MB buffers gets allocated automatically as soon as a track
begins to be processed and it gets freed as soon as the track is done.
The fifos do not wait for buffer fill but writing starts immediately.
In case of external signals expect abort handling of an ongoing burn to
last up to a minute. Wait the normal burning timespan before any kill -9.
For simplicity, this function allows memory leaks in case of failure.
In apps which do not abort immediately, one should clean up better.

/** Overview
telltoc is a minimal demo application for the library libburn as provided
on http://libburnia-project.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
telltoc_read_and_print() reads from data CD or from DVD and prints 7-bit
to stdout (encodings 0,2) or 8-bit to file (encoding 1)
When everything is done, main() releases the drive and shuts down libburn:
burn_drive_release();
burn_finish()

there should be no fatal disturbance of ongoing burns of other libburn
