 *  File:       dxvt.cpp
 *  Content:    Full Duplex Test main program.
 *  History:
 *	Date   By  Reason
 *	============
 *	08/19/99	pnewson		created
 *  09/02/99	pnewson		renamed to dxvt.cpp from fdtest.cpp
 *  11/01/99	rodtoll		Bug #113726 - Voxware integration now uses COM
 *							and this module uses LoadLibrary so we require
 *							a CoInitialize() call.
 *  01/21/2000	pnewson     Running this program with no command line options
 *							now does nothing, since the cpanel is the correct
 *							launch point now.
 *  03/03/2000	rodtoll	    Updated to handle alternative gamevoice build.   
 *  04/19/2000	pnewson	    Error handling cleanup  
 *							removed obsolete retrocfg.h dependency
 *  06/28/2000	rodtoll		Prefix Bug #38026 
 *  07/12/2000	rodtoll Bug #31468 - Add diagnostic spew to logfile to show what is failing the HW Wizard
 *  08/28/2000	masonb  Voice Merge: Removed OSAL_* and dvosal.h, added STR_* and strutils.h
 *  04/02/2001	simonpow	Bug #354859 Fixes for PREfast (BOOL casts on DVGUIDFromString calls)
 *  02/28/2002	rodtoll		WINBUG #550105 - SECURITY: DPVOICE: Dead code
 *							- Removed /RENDER and /CAPTURE command-line processing.  (Broken and not needed)
 *
