*
* #GSocketClient is a high-level utility class for connecting to a
* network host using a connection oriented socket type.
*
* You create a #GSocketClient object, set any options you want, then
* call a sync or async connect operation, which returns a #GSocketConnection
* subclass on success.
*
* The type of the #GSocketConnection object returned depends on the type of
* the underlying socket that is in use. For instance, for a TCP/IP connection
* it will be a #GTcpConnection.
