/** 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-RE, can burn to CD-R,
CD-RW, DVD-R, DVD+R, DVD+R/DL, DVD+RW, DVD-RW, DVD-RAM, BD-RE.
Not supported yet: DVD-R/DL, BD-R.
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
libburner_blank_disc()
or you can format a DVD-RW to profile "Restricted Overwrite" (needed once)
or an unused BD-RE to default size
libburner_format_owrt()
With the aquired drive you can burn to CD or DVD
libburner_payload()
When everything is done, main() releases the drive and shuts down libburn:
burn_drive_release();
burn_finish()

to prefer because it only touches one drive. On modern Linux kernels,
there should be no fatal disturbance of ongoing burns of other libburn
instances with any of our approaches. We use open(O_EXCL) by default.

and to restart when the choice has been made. The list of selectable
drives should also hold persistent drive addresses as obtained
above by burn_drive_get_adr(). By such an address one may use
burn_drive_scan_and_grab() to finally aquire exactly one drive.

before accessing any drives again.
In both cases you have to be aware that the desired drive might get

/** 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.

/* License and copyright aspects:
This all is provided under GPL.
Read. Try. Think. Play. Write yourself some code. Be free of my copyright.
Be also invited to study the code of cdrskin/cdrskin.c et al.
Clarification in my name and in the name of Mario Danic, copyright holder
on toplevel of libburnia. To be fully in effect after the remaining other
copyrighted code has been replaced by ours and by copyright-free contributions
of our friends:
We, the copyright holders, agree on the interpretation that
dynamical linking of our libraries constitutes "use of" and
not "derivation from" our work in the sense of GPL, provided
those libraries are compiled from our unaltered code.
Thus you may link our libraries dynamically with applications
which are not under GPL. You may distribute our libraries and
application tools in binary form, if you fulfill the usual
condition of GPL to offer a copy of the source code -altered
or unaltered- under GPL.
We ask you politely to use our work in open source spirit
and with the due reference to the entire open source community.
If there should really arise the case where above clarification
does not suffice to fulfill a clear and neat request in open source
spirit that would otherwise be declined for mere formal reasons,
only in that case we will duely consider to issue a special license
covering only that special case.
It is the open source idea of responsible freedom which will be
decisive and you will have to prove that you exhausted all own
means to qualify for GPL.
For now we are firmly committed to maintain one single license: GPL.
History:
libburner is a compilation of my own contributions to test/burniso.c and
fresh code which replaced the remaining parts under copyright of
Derek Foreman.
My respect and my thanks to Derek for providing me a start back in 2005.
