/** Create and aquire a pseudo-drive which will accept option settings much
like a MMC burner drive. Many of them will not cause any effect, though.
There are two kinds of pseudo-drives: stdio-drives and null-drives.
A stdio-drive performs all its eventual data transfer activities on a file
via standard i/o functions open(2), lseek(2), read(2), write(2), close(2).
Its capabilities resemble DVD-RAM but the media profile reported is 0x00
and it issues no realistic write space information.
A null-drive is created if the parameter "name" is an empty string. It will
pretend to have loaded no media.
@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.
@param name Sets the file address to be used for writing. Permissible
file types are regular file or block device. If the file
does not exist, it is attempted to create it as regular file.
An empty fname creates a null-drive.
@return 1 success , <=0 failure
