# SCPreferencesSetSpecific

## Overview

The functions in the `SCPreferencesSetSpecific` programming interface allow an application to set specific configuration information about the current system (for example, the computer or sharing name). Note that to access configuration preferences, you must first establish a preferences session using the [`SCPreferencesCreate(_:_:_:)`](/documentation/SystemConfiguration/SCPreferencesCreate(_:_:_:)) function.
