/**
|
||||
|
||||
libisoburn is a frontend for libraries libburn and libisofs which enables
|
||||
creation and expansion of ISO-9660 filesystems on all CD/DVD media supported
|
||||
by libburn. This includes media like DVD+RW, which do not support multi-session
|
||||
management on media level
|
||||
>>> to come: and even plain disk files or other random access file types.
|
||||
|
||||
The price for that is thorough specialization on data files in ISO-9660
|
||||
filesystem images. So libisoburn is not suitable for audio (CD-DA) or any
|
||||
other CD layout which does not entirely consist of ISO-9660 sessions.
|
||||
|
||||
The priciple of this frontend is that you may use any call of libisofs or
|
||||
libburn unless it has a isoburn_*() wrapper listed in the following function
|
||||
idocumentation.
|
||||
E.g. call isoburn_initialize() rather than iso_init(); burn_initialize()
|
||||
and call isoburn_drive_scan_and_grab() rather than burn_drive_scan_and_grab().
|
||||
But you may call burn_disc_get_profile() directly if you want to display
|
||||
the media type.
|
||||
|
||||
The usage model is like with libburn: the target is a "media" in a "drive".
|
||||
The wrappers will transparently provide the necessary emulations which
|
||||
are appropriate for particular target "drives".
|
||||
|
||||
>>> Technical remark:
|
||||
>>> For full support of plain files, libburn needs to get a null-drive
|
||||
>>> which swallows all libburn calls which are not wrapped in isoburn calls.
|
||||
>>> I had a count: ~ 50 API calls with struct burn_drive or
|
||||
>>> struct burn_write_opts to curb :))
