/* test/libburner.c , API illustration of burning a single data track to CD */
/* Copyright (C) 2005 - 2006 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://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.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()
Between blanking and burning one eventually has to reload the drive status
libburner_regrab()
With the aquired drive you can burn to CD-R or blank CD-RW
libburner_payload()
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

/* 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 libburn. 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copyrighted code has been replaced by ours and by copyright-free contributions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.
