/** Aquire a drive with known persistent address.This is the sysadmin friendly
way to open one drive and to leave all others untouched. It bundles
the following API calls to form a non-obtrusive way to use libburn:
burn_drive_add_whitelist() , burn_drive_scan() , burn_drive_grab()
You are *strongly urged* to use this call whenever you know the drive
address in advance.
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_get_adr(&(drive_infos[driveno]), adr) .
Another way is to drop the unwanted drives by burn_drive_info_forget().
@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, and before calling a scan
function again.
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 obtained
by burn_drive_get_adr() or guessed skillfully by application
resp. its user.
