Notes: Be sure to check that the trap _HWPriv is implemented before calling this

routine. See Using the Gestalt Manager for sample code that shows how

to determine whether a trap is implemented. If you call this routine and

_HWPriv is not implemented, you application will crash.

The MC68020, MC68030 and MC68040 micro processors have

instruction caches.
