A Library for creating MusicBrainz DiscIDs
------------------------------------------
libdiscid is a C library for creating MusicBrainz DiscIDs from audio CDs.
It reads a CD's table of contents (TOC) and generates an identifier which
can be used to lookup the CD at MusicBrainz (http://musicbrainz.org).
Additionally, it provides a submission URL for adding the DiscID to the
database.
The library also provides FreeDB disc IDs, and MCN + ISRCs, if available.
The interface of this library is new, but the DiscID algorithm and the
operating system dependent CD-ROM/DVD-ROM access code have been ported
from libmusicbrainz version 2.
Please report all bugs you find via the MusicBrainz bug tracker.
Don't forget to state which OS and what version you are using:
http://tickets.musicbrainz.org/browse/LIB
Questions about this package may be posted to the MusicBrainz
development mailing list (mb-devel):
http://musicbrainz.org/doc/Communication/Mailing_Lists
More information can be found at the package's official homepage:
http://musicbrainz.org/doc/libdiscid

* \mainpage libdiscid
* \section intro Introduction
*
* Libdiscid is a C library for calculating DiscIDs
* (<a href="http://musicbrainz.org/doc/Disc ID">MusicBrainz</a>
* and <a href="http://freedb.org">freedb</a>)
* for Audio CDs.
* Additionally the library can extract the MCN/UPC/EAN and the
* <a href="http://musicbrainz.org/doc/ISRC">ISRCs</a> from disc.
*
* The idea is to have an easy to use library without any dependencies
* that can be used from scripting languages.
*
* The API is documented in discid.h.
*
* \section examples Examples
*
* This is an example of the most basic usage:
*
* \code
*
* DiscId *disc = discid_new();
*
* if ( discid_read_sparse(disc, "/dev/cdrom", 0) == 0 ) {
* fprintf(stderr, "Error: %s\n", discid_get_error_msg(disc));
* return 1;
* }
*
* printf("DiscID : %s\n", discid_get_id(disc));
* printf("Submit via : %s\n", discid_get_submission_url(disc));
*
* discid_free(disc);
*
* \endcode
*
* \section Building
*
* libdiscid provides a pkg-config script that returns the necessary compiler and linker flags, as well as the
* version number. To build a small sample program one would use:
*
* @par
* <tt>gcc libdiscid-test.c \`pkg-config libdiscid --cflags --libs\` -o libdiscid-test</tt>
*
* \section Contact
