**	File:		CODECINS.C
**	Purpose:	Verifys that audio and video support are properly installed
**            under Windows 95 or NT 3.5x.  Under Win95 we ask Windows to
**            install the appropriate sections automatically for the user.
**            Under NT the user is told what and how to install the missing
**            components.
**
**            We verify audio support with the MS-ADPCM codec and
**            video support with MS Video1 and Intel Indeo 3.2 codecs.
**
**	Dependencies:	CODECHEC.CPP is used to do the actual verification and
**            instalation if necessary.  If components need to be installed
**            CODECHEC.CPP uses RUNDLL.EXE to call SETUPX.DLL on Windows95.
**			      These are part of the Windows95 setup that is installed
**			      on a users machine.  Please see geninst.txt for some
**			      more information on these files.

**      pcamfd: Ptr to custom action member function data
**          (variable size, depends on camf type).
**	szData: Ptr to 3rd param of object data from STF

**  Returns:
**      Appropriate RC (return code) value.
