If not, then you have to use directly above calls. In that case, you are *strongly urged* to drop any unintended drive which will be exclusively occupied and not closed by burn_drive_scan(). This can be done by shutting down the library including a call to burn_finish(). You may later start a new libburn session and should then use the function described here with an address obtained after burn_drive_scan() via burn_drive_d_get_adr(drive_infos[driveno].drive,adr). Another way is to drop the unwanted drives by burn_drive_info_forget(). Operating on multiple drives: Different than with burn_drive_scan() it is allowed to call burn_drive_scan_and_grab() without giving up any other scanned drives. So this call can be used to get a collection of more than one aquired drives. The attempt to aquire the same drive twice will fail, though. Pseudo-drives: burn_drive_scan_and_grab() is able to aquire virtual drives which will accept options much like a MMC burner drive. Many of those options will not cause any effect, though. The address of a pseudo-drive begins with prefix "stdio:" followed by a path. Examples: "stdio:/tmp/pseudo_drive" , "stdio:/dev/null" , "stdio:-" If the path is empty, the result is a null-drive = drive role 0. It pretends to have loaded no media and supports no reading or writing. If the path leads to an existing regular file, or to a not yet existing file, or to an existing block device, then the result is a random access stdio-drive capable of reading and writing = drive role 2. If the path leads to an existing file of any type other than directory, then the result is a sequential write-only stdio-drive = drive role 3. The special address form "stdio:/dev/fd/{number}" is interpreted literally as reference to open file descriptor {number}. This address form coincides with real files on some systems, but it is in fact hardcoded in libburn. Special address "stdio:-" means stdout = "stdio:/dev/fd/1". The role of such a drive is determined by the file type obtained via fstat({number}). Roles 2 and 3 perform all their eventual data transfer activities on a file via standard i/o functions open(2), lseek(2), read(2), write(2), close(2). The media profile is reported as 0xffff. Write space information from those media is not necessarily realistic. The capabilities of role 2 resemble DVD-RAM but it can simulate writing. If the path does not exist in the filesystem yet, it is attempted to create it as a regular file as soon as write operations are started. The capabilities of role 3 resemble a blank DVD-R. Nevertheless each burn_disc_write() run may only write a single track. One may distinguish pseudo-drives from MMC drives by call burn_drive_get_drive_role(). @param drive_infos On success returns a one element array with the drive (cdrom/burner). Thus use with driveno 0 only. On failure the array has no valid elements at all. The returned array should be freed via burn_drive_info_free() when it is no longer needed. This is a result from call burn_drive_scan(). See there. Use with driveno 0 only. @param adr The persistent address of the desired drive. Either once obtained by burn_drive_d_get_adr() or composed skillfully by application resp. its user. E.g. "/dev/sr0".

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.
