# typeMachPort

For specifying a Mach port.

## Overview

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.
