Leopard Sample Code: Networking
Core Foundation provides support for the major networking protocols and services. Core Foundation defines several opaque types that correspond to Mach ports, message ports, BSD sockets, and URLs. Developers can use these objects to communicate between multiple threads and processes, and between computers over a network.
