55	// Parameter Blocks for AudioCodec Component Routines
56	//
57	// Note that the arguments for all the AudioCodec component routines are
58	// 4 bytes in size (assuming pointers are 4 bytes). This means that even on
59	// Windows (where all arguments are forced into SInt32s), we can get away with
60	// mass casting the argument list through the appropriate paramblock structure.
61	// This gets around the fact that the component glue passes the arguments in
62	// a different order depending on the platform and therefore makes writing the
63	// calling glue and the dispatcher much simpler.
