|
|

|
|
||||||
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()

For a file on disk, do:

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

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

i believe. But cdrecord had long years of time to complete itself.
