Unless I am missing the point of your question, the answer is that there
is no 'source' code to be had.  Microsoft distributes a DOS extension that
allows any program to access a CD-ROM as though it is just another (very
large) disk on the pc.  Your standard c library of file routines (open, close,
fread, etc) will work as normal.  The Microsoft extensions are usually
included with the CD-ROM player when purchased but may also be obtained
seperately.
