/******************************Module*Header*******************************\
* Module Name: database.c
*
* 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.
*
* Warning:
* These functions ARE NOT THREAD safe.
* The functions in this file MUST only be called on the UI thread. Before
* calling any of the functions the CALLER MUST call LockTableOfContents
* for the specified cdrom device.
*
* 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.
*
