//
//	Function:
//
//		PNCodec_Open
//
//	Purpose:
//		PNCodec_Open() attempts to load a codec whose type is specified 
//		by moftFormatTag.  Some currently used codec HX_MOFTAGs are:
//		RA_FORMAT_3_ID	RealAudio 14.4 audio codec
//		RA_FORMAT_4_ID	RealAudio 28.8 audio codec 
//
//	Parameters:
//		moftFormatTag - the 4 byte codec identifier
//		codecRef - the HXCODEC reference is returned in codecRef. 
//		You will need to use this 	reference in all future HXCodec_XXX() functions.
//
//	Return:
//		S_OK - loading of codec was successful.
//		HXR_OUTOFMEMORY - insufficient memory to load codec.
//		HXCODEC_LOAD_ERR - unable to load codec.
