perl v5.40.0                                       2024-10-20                           MusicBrainz::DiscID(3pm)

       MusicBrainz::DiscID is a class to calculate a MusicBrainz DiscID from an audio CD in the drive. The
       coding style is slightly different to the C interface to libdiscid, because it makes use of perl's Object
       Oriented functionality.

       MusicBrainz::DiscID::default_device()
           Returns a device string for the default device for this platform.

       MusicBrainz::DiscID::new( [$device] )
           Construct a new DiscID object.

           As an optional argument the name of the device to read the ID from may be given. If you don't specify
           a device here you can later read the ID with the read method.

       $discid->error_msg()
           Return a human-readable error message of the last error that occurred.

       $discid->first_track_num()
           Return the number of the first track on this disc (usually 1).  Returns undef if no ID was yet read.

       $discid->last_track_num()
           Return the number of the last track on this disc.

       $discid->id()
           Returns the DiscID as a string.  Returns undef if no ID was yet read.

       $discid->last_track_num()
           Return the number of the last track on this disc.  Returns undef if no ID was yet read.

       $discid->put( $first_track, $sectors, $offset1, $offset2, ... )
           This  function  may  be  used  if the TOC has been read earlier and you want to calculate the disc ID
           afterwards, without accessing the disc drive.

       $discid->read( [$device] )
           Read the disc ID from the given device.  If no device is given the default  device  of  the  platform
           will  be used.  On error, this function returns false and sets the error message which you can access
           $discid->error_msg().

       $discid->sectors()
           Return the length of the disc in sectors.  Returns undef if no ID was yet read.

       $discid->submission_url()
           Returns a submission URL for the DiscID as a string.  Returns undef if no ID was yet read.

       $discid->track_length( $track_num )
           Return the length of a track in sectors.

       $discid->track_offset( $track_num )
           Return the sector offset of a track.
