* $Log: /DescentIII/Main/dd_sndlib/ddsoundload.cpp $
*
* 17 3/20/00 12:23p Matt
* Merge of Duane's post-1.3 changes.
* Fixed bug with sounds not being deleted
*
* 16 10/23/99 5:12p 3dsmax
* use GlobalAlloc for win32 instead of mem_malloc for now (restored
* original code)
*
* 15 10/22/99 8:10a Kevin
* Fixed bug introduced from the mac merge
*
* 14 10/21/99 9:27p Jeff
* B.A. Macintosh code merge
*
* 13 4/17/99 1:53a Jeff
* made platform 'independant' so other low-level sound libs can include
* without having to double code
*
* 12 4/06/99 8:29p Samir
* added error check system.
*
* 11 2/16/99 12:42p Kevin
* Improvements to the paging data progress indicator
*
* 10 2/09/99 7:01p Kevin
* First work for new and improved progress screen while loading a level.
* Note that this is a hack at this point, while I get the details worked
* out, then I'll make it cleaner.
*
* 9 1/14/99 6:10p Samir
* added DirectSound buffer duplication code.
*
* 8 10/22/98 8:31p Chris
* Sounds use GlobalAlloc and GlobalFree
*
* 7 10/19/98 11:57a Chris
* Update the sound system to use the import volume
*
* 6 10/12/98 1:27p Jeff
* all mem_free's do set the value to NULL after they are complete
*
* 5 10/12/98 11:30a Kevin
* More memory stuff
*
* 4 10/08/98 1:18a Chris
* Now it is non-Intel platform friendly.
*
* 3 10/08/98 1:09a Chris
* Speed up the sound paging in. -- Fucks up if byte ordering if different
* then for the Intel platform.
*
* 2 7/24/98 5:23p Samir
* moved sound variables from soundload to ssl_lib.h (and WAV file stuff)
*
* 1 7/20/98 2:54p Samir
* moved code from sndlib.
