13         if ( $disc->read() == 0 ) {
14             print STDERR "Error: " . $discid->error_msg() . "\n";

DESCRIPTION

20       MusicBrainz::DiscID is a class to calculate a MusicBrainz DiscID from
21       an audio CD in the drive. The coding style is slightly different to the
22       C interface to libdiscid, because it makes use of perl's Object
23       Oriented functionality.
24
25       MusicBrainz::DiscID::default_device()
26           Returns a device string for the default device for this platform.
27
28       MusicBrainz::DiscID::new( [$device] )
29           Construct a new DiscID object.
30
31           As an optional argument the name of the device to read the ID from
32           may be given. If you don't specify a device here you can later read
33           the ID with the read method.
34
35       $discid->error_msg()
36           Return a human-readable error message of the last error that
37           occured.
38
39       $discid->first_track_num()
40           Return the number of the first track on this disc (usually 1).
41           Returns undef if no ID was yet read.
42
43       $discid->last_track_num()
44           Return the number of the last track on this disc.
45
46       $discid->id()
47           Returns the DiscID as a string.  Returns undef if no ID was yet
48           read.
49
50       $discid->last_track_num()
51           Return the number of the last track on this disc.  Returns undef if
52           no ID was yet read.
53
54       $discid->put( $first_track, $sectors, $offset1, $offset2, ... )
55           This function may be used if the TOC has been read earlier and you
56           want to calculate the disc ID afterwards, without accessing the
57           disc drive.
58
59       $discid->read( [$device] )
60           Read the disc ID from the given device.  If no device is given the
61           default device of the platform will be used.  On error, this
62           function returns false and sets the error message which you can
63           access $discid->error_msg().
64
65       $discid->sectors()
66           Return the length of the disc in sectors.  Returns undef if no ID
67           was yet read.
68
69       $discid->submission_url()
70           Returns a submission URL for the DiscID as a string.  Returns undef
71           if no ID was yet read.
72
73       $discid->track_length( $track_num )
74           Return the length of a track in sectors.
75
76       $discid->track_offset( $track_num )
77           Return the sector offset of a track.
