* @see_also: #GUnixConnection, #GSocketControlMessage
*
* This #GSocketControlMessage contains a #GCredentials instance. It
* may be sent using g_socket_send_message() and received using
* g_socket_receive_message() over UNIX sockets (ie: sockets in the
- * %G_SOCKET_ADDRESS_UNIX family).
+ * %G_SOCKET_FAMILY_UNIX family).
*
* For an easier way to send and receive credentials over
- * stream-oriented UNIX sockets, see g_unix_connection_send_credentials() and
- * g_unix_connection_receive_credentials().
- **/
+ * stream-oriented UNIX sockets, see
+ * g_unix_connection_send_credentials() and
+ * g_unix_connection_receive_credentials(). To receive credentials of
+ * a foreign process connected to a socket, use
+ * g_socket_get_credentials().
