# SCNetworkConfiguration

## Overview

Overview The SCNetworkConfiguration programming interface provides access to the stored network configuration. The functions include providing access to the network-capable devices on the system, the network sets, network services, and network protocols. Note that these functions follow Core Foundation function-name conventions. A function that has “Create” or “Copy” in its name returns a reference you must release with the CFRelease function. Note that when using the functions in this programming interface, you must call the SCPreferencesCommitChanges(_:) function to ensure that your changes are committed to permanent storage.
