// 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.
