Cocoa in a Nutshell

Name

NSSocketPortNameServer — Mac OS X 10.0

Synopsis

This subclass of NSPortNameServer accepts and returns instances of NSSocketPort. NSConnection objects use port name servers to register and discover communication ports that can be used for distributed objects connections. Additional subclasses of NSPortNameServer that handle other types of ports are NSMachBootstrapServer and NSMessagePortNameServer.

Unlike the other port name server classes, NSSocketPortNameServer can operate over a network. NSSocketPortNameServer is implemented using the Foundation framework’s implementation of Rendezvous found in NSNetService. Clients are able to discover socket ports by name only.

Note: this class did not function in versions of Mac OS X prior to 10.2.
