discisrc.c

This example code uses libdiscid to read the TOC, MCN and ISRCs from a CD.If supported by the platform and provided by the CD the MCN for the disc and ISRCs for each track will be printed.

The CD device to use can be specified as the first command line parameter. If none is given the platform's default device will be used.
