//  Parameter Blocks for AudioCodec Component Routines

//

//  Note that the arguments for all the AudioCodec component routines are

//  4 bytes in size (assuming pointers are 4 bytes). This means that even on

//  Windows (where all arguments are forced into SInt32s), we can get away with

//  mass casting the argument list through the appropriate paramblock structure.

//  This gets around the fact that the component glue passes the arguments in

//  a different order depending on the platform and therefore makes writing the

//   calling glue and the dispatcher much simpler.
