XDestroyWindow, XDestroySubwindows - destroy windows

display   Specifies the connection to the X server.

       w         Specifies the window.

       The XDestroyWindow function destroys the specified window as well as all of its subwindows and causes the
       X server to generate a DestroyNotify event for each window.  The window should never be referenced again.
       If  the  window specified by the w argument is mapped, it is unmapped automatically.  The ordering of the
       DestroyNotify events is such that for any given window being destroyed, DestroyNotify is generated on any
       inferiors of the window before being generated on the window itself.  The  ordering  among  siblings  and
       across  subhierarchies  is  not  otherwise constrained.  If the window you specified is a root window, no
       windows are destroyed.  Destroying a mapped window will generate Expose events on other windows that were
       obscured by the window being destroyed.

       XDestroyWindow can generate a BadWindow error.

       The XDestroySubwindows function destroys all inferior windows of the specified window,  in  bottom-to-top
       stacking order.  It causes the X server to generate a DestroyNotify event for each window.  If any mapped
       subwindows  were  actually destroyed, XDestroySubwindows causes the X server to generate Expose events on
       the specified window.  This is much more efficient than deleting many windows one at a time because  much
       of  the  work  need  be  performed  only  once  for all of the windows, rather than for each window.  The
       subwindows should never be referenced again.

       XDestroySubwindows can generate a BadWindow error.

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