//	Function:
//
//		FindLibrary()
//
//	Purpose:
//
//		Called to get the fragment/file name of a Mac Shared Library given
//		the library's creator and codec ID. The Codec ID is stored in STR#9000;
//		item #1 of the library.
//
//	Parameters:
//
//		HX_MOFTAG moftCodecTag
//		The four character codec identifier (RV10, dnet, ...)
//
//		OSType codecCreator
//		The Creator type of the codec; currently kDecoderCreator or kEncoderCreator
//		
//		char* pLibName
//		Allocate this before calling FindLibrary. Library file name is
//		returned in it. Library's fragment name should be same as file name!!
//
//	Return:
//
//		HX_RESULT
//		Error code indicating the success or failure of the function.
