+/**
+ * SECTION:gtksocket
+ * @Short_description: Container for widgets from other processes
+ * @Title: GtkSocket
+ * @include: gtk/gtkx.h
+ * @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.
+ *
+ * <note>
+ * The #GtkPlug and #GtkSocket widgets are only available when GTK+
+ * is compiled for the X11 platform and %GDK_WINDOWING_X11 is defined.
+ * They can only be used on a #GdkX11Display. To use #GtkPlug and
+ * #GtkSocket, you need to include the <filename>gtk/gtkx.h</filename>
+ * header.
+ * </note>
