NSPort Mac OS X 10.0

This class is an abstract class that declares the interface to objects that serve as endpoints for communication between two threads or tasks. Cocoa's distributed objects system implements interprocess communication using subclasses of NSPort. The Foundation framework implements three concrete subclasses of NSPort: NSMessagePort, NSMachPort, and NSSocketPort. NSMessagePort and NSMachPort are used for local communications only, while NSSocketPort can be used for either local or remote communication over a network.
