       XUnmapWindow, XUnmapSubwindows - unmap windows

       int XUnmapWindow(Display *display, Window w);

       int XUnmapSubwindows(Display *display, Window w);

       display	 Specifies the connection to the X server.

       w	 Specifies the window.

       The XUnmapWindow function unmaps the specified window and causes the X server to generate
       an UnmapNotify event.  If the specified window is already unmapped, XUnmapWindow has no
       effect.	Normal exposure processing on formerly obscured windows is performed.  Any child
       window will no longer be visible until another map call is made on the parent.  In other
       words, the subwindows are still mapped but are not visible until the parent is mapped.
       Unmapping a window will generate Expose events on windows that were formerly obscured by

       XUnmapWindow can generate a BadWindow error.

       The XUnmapSubwindows function unmaps all subwindows for the specified window in bottom-to-
       top stacking order.  It causes the X server to generate an UnmapNotify event on each sub-
       window and Expose events on formerly obscured windows.  Using this function is much more
       efficient than unmapping multiple windows one at a time because the server needs to per-
       form much of the work only once, for all of the windows, rather than for each window.

       XUnmapSubwindows can generate a BadWindow error.

       BadWindow A value for a Window argument does not name a defined Window.
