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:
burn_app_aquire_by_adr() demonstrates usage as of cdrecord traditions
burn_app_aquire_by_driveno() demonstrates a scan-and-choose approach
With that aquired drive you blank a CD-RW
burn_app_blank_disc()
Between blanking and burning one eventually has to reload the drive status
burn_app_regrab()
With the aquired drive you can burn to CD-R or blank CD-RW
burn_app_payload()
When everything is done, main() releases the drive and shuts down libburn:
burn_drive_release();
burn_finish()

On modern Linux kernels, race conditions are supposed to end up by
having one single winner or by having all losers. On modern Linux
kernels, there should be no fatal disturbance of ongoing burns
of other libburn instances. We use open(O_EXCL) by default.
There are variants of cdrecord which participate in advisory O_EXCL
locking of block devices. Others possibly don't. Some kernels do
nevertheless impose locking on open drives anyway (e.g. SuSE 9.0, 2.4.21).

/** Brings the preformatted image (ISO 9660, afio, ext2, whatever) onto media.
To make sure your image is readable on any Linux machine, you should
add at least 300 kB of padding. This program will not do this for you.
For a file on disk, do:
dd if=/dev/zero bs=1K count=300 >>my_image_file
For on-the-fly streams it suffices to add the 300 kB to the argument for
--stdin_size (which is then needed due to lack of TAO mode).
Without a signal handler it is quite dangerous to abort the process
while this function is active. See cdrskin/cdrskin.c and its usage
of cdrskin/cleanup.[ch] for an example of application provided
abort handling. It must cope with 2 of 3 threads reporting for
being handled.
Without signal handler have ready a command line
cdrecord dev=... -reset
with a dev= previously inquired by cdrecord [dev=ATA] -scanbus
in order to get your drive out of shock state after raw abort.
Thanks to Joerg Schilling for helping out unquestioned. :)
In general, libburn is less prone to system problems than cdrecord,
i believe. But cdrecord had long years of time to complete itself.
We are still practicing. Help us with that. :))
