Overview.
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 and even plain disk files or block devices.
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.
Connector functions
libisofs and libburn do not depend on each other but share some interfaces by which they can cooperate. libisoburn establishes the connection between both modules by creating the necessary interface objects and attaching them to the right places.
Wrapper functions
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 documentation.
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 wrappers will transparently provide the necessary emulations which are appropriate for particular target drives and media states. To learn about them you have to read both API descriptions: the one of the wrapper and the one of the underlying libburn or libisofs call.
Macros BURN_* and functions burn_*() are documented in <libburn/libburn.h> Macros ISO_* and functions iso_*() are documented in <libisofs/libisofs.h>
Usage model
There may be an input drive and an output drive. Either of them may be missing with the consequence that no reading resp. writing is possible. Both drive roles can be fulfilled by the same drive.
Input can be a random access readable libburn drive: optical media, regular files, block devices. Output can be any writeable libburn drive: writeable optical media in burner, writeable file objects (no directories).
libburn demands rw-permissions to drive device file resp. file object.
If the input drive provides a suitable ISO RockRidge image, then its tree may be loaded into memory and can then be manipulated by libisofs API calls. The loading is done by isoburn_read_image() under control of struct isoburn_read_opts which the application obtains from libisoburn and manipulates by the family of isoburn_ropt_set_*() functions.
Writing of result images is controlled by libisofs related parameters in a struct isoburn_imgen_opts which the application obtains from libisoburn and manipulates by the family of isoburn_igopt_set_*() functions.
All multi-session aspects are handled by libisoburn according to these settings. The application does not have to analyze media state and write job parameters. It rather states its desires which libisoburn tries to fulfill, or else will refuse to start the write run.
Setup for Growing, Modifying or Blind Growing
The connector function family offers alternative API calls for performing the setup for several alternative image generation strategies.
Growing: If input and output drive are the same, then isoburn_prepare_disc() is to be used. It will lead to an add-on session on appendable or overwriteable media with existing ISO image. With blank media it will produce a first session.
Modifying: If the output drive is not the input drive, and if it bears blank media or overwriteable without a valid ISO image, then one may produce a consolidated image with old and new data. This will copy file data from an eventual input drive with valid image, add any newly introduced data from the local filesystem, and produce a first session on output media. To prepare for such an image generation run, use isoburn_prepare_new_image().
Blind Growing: This method reads the old image from one drive and writes the add-on session to a different drive. That output drive is nevertheless supposed to finally lead to the same media from where the session was loaded. Usually it will be stdio:/dev/fd/1 (i.e. stdout) being piped into some burn program like with this classic gesture: mkisofs -M $dev -C $msc1,$nwa | cdrecord -waiti dev=$dev Blind growing is prepared by the call isoburn_prepare_blind_grow(). The input drive should be released immediately after this call in order to allow the consumer of the output stream to access that drive for writing.
After either of these setups, some peripheral libburn drive parameter settings like burn_write_opts_set_simulate(), burn_write_opts_set_multi(), burn_drive_set_speed(), burn_write_opts_set_underrun_proof() should be made. Do not set the write mode. It will be chosen by libisoburn so it matches job and media state.
Writing the image
Then one may start image generation and write threads by isoburn_disc_write(). Progress may be watched at the output drive by burn_drive_get_status() and isoburn_get_fifo_status().
At some time, the output drive will be BURN_DRIVE_IDLE indicating that writing has ended. One should inquire isoburn_drive_wrote_well() to learn about overall success.
Finally one must call isoburn_activate_session() which will complete any eventual multi-session emulation.
Application Constraints
Applications shall include libisofs/libisofs.h , libburn/libburn.h and this file itself: libisoburn/libisoburn.h . They shall link with -lisofs -lburn -lisoburn or with the .o files emerging from building those libraries from their sources.
Applications must use 64 bit off_t, e.g. on 32-bit Linux by defining define _LARGEFILE_SOURCE define _FILE_OFFSET_BITS 64 or take special precautions to interface with the library by 64 bit integers where above .h files prescribe off_t. Not to use 64 bit file i/o will keep the application from producing and processing ISO images of more than 2 GB size. Initialize libisoburn, libisofs and libburn.

Set up isoburn_disc_get_msc1() to return a fabricated value.
This makes only sense between aquiring the drive and reading the image. After isoburn_read_image() it will confuse the coordination of libisoburn and libisofs. Note: Sessions and tracks are counted beginning with 1, not with 0.

Note: Above version numbers are also recorded in configure.ac because libtool wants them as parameters at build time.
For the library compatibility check, ISOBURN_*_VERSION in configure.ac are not decisive. Only the three numbers here do matter. Usage discussion:Some developers of the libburnia project have differing opinions how to ensure the compatibility of libaries and applications.
It is about whether to use at compile time and at runtime the version numbers isoburn_header_version_* provided here. Thomas Schmitt advises to use them. Vreixo Formoso advises to use other means.
At compile time:
Vreixo Formoso advises to leave proper version matching to properly programmed checks in the the application's build system, which will eventually refuse compilation.
Thomas Schmitt advises to use the macros defined here for comparison with the application's requirements of library revisions and to eventually break compilation.
Both advises are combinable. I.e. be master of your build system and have if checks in the source code of your application, nevertheless.
At runtime (via *_is_compatible()):
Vreixo Formoso advises to compare the application's requirements of library revisions with the runtime library. This is to allow runtime libraries which are young enough for the application but too old for the lib*.h files seen at compile time.
Thomas Schmitt advises to compare the header revisions defined here with the runtime library. This is to enforce a strictly monotonous chain of revisions from app to header to library, at the cost of excluding some older libraries.
These two advises are mutually exclusive.
-----------------------------------------------------
For an implementation of the Thomas Schmitt approach, see libisoburn/burn_wrap.c : isoburn_initialize() This connects libisoburn as "application" with libisofs as "library".
The compatible part of Vreixo Formoso's approach is implemented in configure.ac LIBBURN_REQUIRED, LIBISOFS_REQUIRED. In isoburn_initialize() it would rather test by iso_lib_is_compatible(isoburn_libisofs_req_major,... than by iso_lib_is_compatible(iso_lib_header_version_major,... and would leave out the ugly compile time traps. Announce to the library an application provided method for immediate delivery of messages. It is used when no drive is affected directly or if the drive has no own msgs_submit() method attached by isoburn_drive_set_msgs_submit. If no method is preset or if the method is set to NULL then libisoburn delivers its messages through the message queue of libburn.
