       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
       subwindow  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
       perform 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.
