SCNetworkConnection

Overview

The SCNetworkConnection programming interface contains functions that allow an application to control connection-oriented services defined in the system and get connection-status information. Note that these functions allow you to control and get information about existing services only. If you need to create, change, or remove services, you should use the SCNetworkConfiguration programming interface instead.
