Module Name:


    database.c


Abstract:


    This module implements the database routines for the CD Audio app.
    The information is stored in the ini file "cdaudio.ini" which should
    be located in the nt\windows directory.



Author:


    Rick Turner (ricktu) 31-Jan-1992


Revision History:

    04-Aug-1992 (ricktu)    Incorperated routines from old cdaudio.c,
                            and made work w/new child window framework.
