ARGUMENTS

       Specifies the connection to the X server.  Specifies the window.

DESCRIPTION

       The  XMapWindow function maps the window and all of its subwindows that have had map requests. Mapping a window that has an unmapped ances-
       tor does not display the window but marks it as eligible for display when the ancestor becomes mapped. Such a window is called  unviewable.
       When  all  its ancestors are mapped, the window becomes viewable and will be visible on the screen if it is not obscured by another window.
       This function has no effect if the window is already mapped.

       If the override-redirect of the window is False and if some other client has selected SubstructureRedirectMask on the parent  window,  then
       the X server generates a MapRequest event, and the XMapWindow function does not map the window.	Otherwise, the window is mapped, and the X
       server generates a MapNotify event.

       If the window becomes viewable and no earlier contents for it are remembered, the X server tiles the window with  its  background.  If  the
       window's  background  is undefined, the existing screen contents are not altered, and the X server generates zero or more Expose events. If
       backing-store was maintained while the window was unmapped, no Expose events are generated. If backing-store  will  now	be  maintained,  a
       full-window  exposure is always generated. Otherwise, only visible regions may be reported.  Similar tiling and exposure take place for any
       newly viewable inferiors.

       If the window is an InputOutput window, XMapWindow generates Expose events on each InputOutput window that it causes to	be  displayed.	If
       the client maps and paints the window and if the client begins processing events, the window is painted twice. To avoid this, first ask for
       Expose events and then map the window, so the client processes input events as usual.  The event list will include Expose for  each  window
       that has appeared on the screen. The client's normal response to an Expose event should be to repaint the window. This method usually leads
       to simpler programs and to proper interaction with window managers.

       XMapWindow can generate a BadWindow error.

       The XMapRaised function essentially is similar to XMapWindow in that it maps the window and  all  of  its  subwindows  that  have  had  map
       requests. However, it also raises the specified window to the top of the stack.

       XMapRaised can generate a BadWindow error.

       The  XMapSubwindows  function  maps  all  subwindows  for a specified window in top-to-bottom stacking order. The X server generates Expose
       events on each newly displayed window. This may be much more efficient than mapping many 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.

       XMapSubwindows can generate a BadWindow error.

DIAGNOSTICS

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