/** 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()
|
||||||
|
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 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()
|
||||||
|
|
||||||
|

compact call and alternatively as application controllable gestures of

whitelisting, scanning for drives and finally grabbing one of them.
|
||||||
|
|
||||||
|
If you have a persistent address of the drive, then the compact call is
|
||||||
|
to prefer. It avoids a shutdown-init cycle of libburn and thus is more
|
||||||
|
safe against race conditions between competing users of that drive.
|
||||||
|
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).

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:

For on-the-fly streams it suffices to add the 300 kB to the argument for

Without a signal handler it is quite dangerous to abort the process

of cdrskin/cleanup.[ch] for an example of application provided

abort handling. It must cope with 2 of 3 threads reporting for

|

|
|

|
Without signal handler have ready a command line

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. :))
