+/**
+ * gdk_window_set_fullscreen_mode:
+ * @window: a toplevel #GdkWindow
+ * @mode: fullscreen mode
+ *
+ * Specifies whether the @window should span over all monitors (in a multi-head
+ * setup) or only the current monitor when in fullscreen mode.
+ *
+ * The @mode argument is from the #GdkFullscreenMode enumeration.
+ * If #GDK_FULLSCREEN_ON_ALL_MONITORS is specified, the fullscreen @window will
+ * span over all monitors from the #GdkScreen.
+ *
+ * On X11, searches through the list of monitors from the #GdkScreen the ones
+ * which delimit the 4 edges of the entire #GdkScreen and will ask the window
+ * manager to span the @window over these monitors.
+ *
+ * If the XINERAMA extension is not available or not usable, this function
+ * has no effect.
+ *
+ * Not all window managers support this, so you can't rely on the fullscreen
+ * window to span over the multiple monitors when #GDK_FULLSCREEN_ON_ALL_MONITORS
+ * is specified.
+ *
+ * Since: 3.8
