typeMachPort
For specifying a Mach port.
Overview
You might use this constant as part of sending an Apple event to an arbitrary Mach port. Your code for creating the descriptor might look like the following:
mach_port_t port = lookupPortForTarget(); // User routine to get port.
// Now create a descriptor with it:
AECreateDesc(typeMachPort, &port, sizeof(port), &desc);Actually sending an Apple event to a Mach port is an advanced technique and is not documented here.
