+/**
+ * SECTION:gtksocket
+ * @Short_description: Container for widgets from other processes
+ * @Title: GtkSocket
+ * @See_also: #GtkPlug, <ulink url="http://www.freedesktop.org/Standards/xembed-spec">XEmbed</ulink>
+ *
+ * Together with #GtkPlug, #GtkSocket provides the ability
+ * to embed widgets from one process into another process
+ * in a fashion that is transparent to the user. One
+ * process creates a #GtkSocket widget and passes
+ * that widget's window ID to the other process,
+ * which then creates a #GtkPlug with that window ID.
+ * Any widgets contained in the #GtkPlug then will appear
+ * inside the first application's window.
+ *
+ * The socket's window ID is obtained by using
+ * gtk_socket_get_id(). Before using this function,
+ * the socket must have been realized, and for hence,
+ * have been added to its parent.
+ *
+ * <example>
+ * <title>Obtaining the window ID of a socket.</title>
+ * <programlisting>
+ * GtkWidget *socket = gtk_socket_new (<!-- -->);
+ * gtk_widget_show (socket);
+ * gtk_container_add (GTK_CONTAINER (parent), socket);
+ *
+ * /<!---->* The following call is only necessary if one of
+ * * the ancestors of the socket is not yet visible.
+ * *<!---->/
+ * gtk_widget_realize (socket);
+ * g_print ("The ID of the sockets window is %#x\n",
+ * gtk_socket_get_id (socket));
+ * </programlisting>
+ * </example>
+ *
+ * Note that if you pass the window ID of the socket to another
+ * process that will create a plug in the socket, you
+ * must make sure that the socket widget is not destroyed
+ * until that plug is created. Violating this rule will
+ * cause unpredictable consequences, the most likely
+ * consequence being that the plug will appear as a
+ * separate toplevel window. You can check if the plug
+ * has been created by using gtk_socket_get_plug_window(). If
+ * it returns a non-%NULL value, then the plug has been
+ * successfully created inside of the socket.
+ *
+ * When GTK+ is notified that the embedded window has been
+ * destroyed, then it will destroy the socket as well. You
+ * should always, therefore, be prepared for your sockets
+ * to be destroyed at any time when the main event loop
+ * is running. To prevent this from happening, you can
+ * connect to the #GtkSocket::plug-removed signal.
+ *
+ * The communication between a #GtkSocket and a #GtkPlug follows the
+ * <ulink url="http://www.freedesktop.org/Standards/xembed-spec">XEmbed</ulink>
+ * protocol. This protocol has also been implemented in other toolkits, e.g.
+ * <application>Qt</application>, allowing the same level of integration
+ * when embedding a <application>Qt</application> widget in GTK or vice versa.
+ *
+ * A socket can also be used to swallow arbitrary
+ * pre-existing top-level windows using gtk_socket_steal(),
+ * though the integration when this is done will not be as close
+ * as between a #GtkPlug and a #GtkSocket.
+ *
+ * <note>
+ * The #GtkPlug and #GtkSocket widgets are currently not available
+ * on all platforms supported by GTK+.
+ * </note>
