55 * @short_description: Helper for connecting to a network service
57 * @see_also: #GSocketConnection, #GSocketListener
59 * #GSocketClient is a lightweight high-level utility class for connecting to
60 * a network host using a connection oriented socket type.
62 * You create a #GSocketClient object, set any options you want, and then
63 * call a sync or async connect operation, which returns a #GSocketConnection
64 * subclass on success.
66 * The type of the #GSocketConnection object returned depends on the type of
67 * the underlying socket that is in use. For instance, for a TCP/IP connection
68 * it will be a #GTcpConnection.
70 * As #GSocketClient is a lightweight object, you don't need to cache it. You
71 * can just create a new one any time you need one.
