XDestroySubwindows()													      XDestroySubwindows()

Name
  XDestroySubwindows - destroy all subwindows of a window.

Synopsis
  XDestroySubwindows(display, w)
	Display *display;
	Window w;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  w	    Specifies the ID of the window whose subwindows are to be destroyed.

Description
  This function destroys all descendants of the specified window (recursively), in bottom to top stacking order.

  XDestroySubwindows()	generates exposure events on window w, if any mapped subwindows were actually destroyed.  This is much more efficient
  than deleting many subwindows one at a time, since much of the work need only be performed once for all of the windows rather than for each
  window.   It	also  saves  multiple exposure events on the windows about to be destroyed.  The subwindows should never again be referenced.
  The X server generates a DestroyNotify event for each window destroyed.

  XCloseDisplay() automatically destroys all windows that have been created by that client on the specified display (unless  called  after  a
  fork system call).

  Never call XDestroySubwindows() with the window argument set to the root window!  This will destroy all the applications on the screen, and
  if there is only one screen, often the server as well.

Errors
  BadWindow

NAME

       XDestroyWindow, XDestroySubwindows - destroy windows

SYNTAX

       int XDestroyWindow(Display *display, Window w);

       int XDestroySubwindows(Display *display, Window w);

ARGUMENTS

       display	 Specifies the connection to the X server.

       w	 Specifies the window.

DESCRIPTION

       The XDestroyWindow function destroys the specified window as well as all of its subwindows and causes the X server to generate a DestroyNo-
       tify 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 gen-
       erated 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 refer-
       enced again.

       XDestroySubwindows can generate a BadWindow error.

DIAGNOSTICS

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