// $Log: cdxsound.h,v $
// Revision 1.4  2000/08/21 21:21:02  mindcry
// Removed all fstreams and exchanged them with CDXFile. I had to do this
// cause fstream wasn't working right with MFC apps/games and also in some
// circumstances it crashed or not opened the file. Sorry for breaking
// backwards compatibility in some ways. But it was necessary.
//
// Revision 1.3  2000/05/10 23:29:26  hebertjo
// Cleaned up all the old code that was commented out.  Version 3.0 is getting
// very close to release.
//
// Revision 1.2  2000/05/01 17:06:26  hebertjo
// Many small changes.  Fixed a few problems identified by BoundsChecker.
// Removed some old code that was commented out.  Cleaned up the look of
// some of the code.
//
// Revision 1.1.1.1  2000/04/22 16:11:35  hebertjo
// Initial checkin of v3.0 to SourceForge CVS.
//
// Revision 2.17  2000/03/04 11:48:01  Mindcry
// small bugfix to compile correct with dx6
//
// Revision 2.16  2000/03/01 09:16:42  Mindcry
// Many changes:
// - Rewritten totally the loading routines
// - Streamed playback of wavefiles
// - ACM Decompressing of wave files (define CDX_ACM_SUPPORT)
// - 3d sound support
// - exclusive mode
// - primary buffer continuos play
// - and much much more
//
// Revision 2.13  2000/02/01 12:58:46  Mindcry
// - changed the last few functions to return a HRESULT
// - fixed the strange memory (loading) bug
//
// Revision 2.12  2000/02/01 11:27:20  Mindcry
// - SetFormat and ContinuousPlay are working now correct
// - Cleaned up the code a bit more
//
// Revision 2.11  2000/01/29 00:50:57  Mindcry
// Initial Release Checkin for 3.0:
// - Playing the Primary Buffer Continuously
// - Allow the User to change the Sound Output Format
// - Exclusive Mode
// - Privatizing of the Variables and some internal functions
// - Extended Error Returning (CDXSound only)
//
// $Revision: 1.4 $
