XUnmapWindow()															    XUnmapWindow()

Name
  XUnmapWindow - unmap a window.

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

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

  w	    Specifies the window ID.

Description
  XUnmapWindow()  removes  w and all its descendants from the screen (but does not unmap the descendents).  If w is already unmapped, XUnmap-
  Window() has no effect.  Otherwise, w is unmapped and an UnmapNotify event is generated.  Normal exposure processing on  formerly  obscured
  windows is performed.

  Descendants of w will not be visible until w is mapped again.  In other words, the subwindows are still mapped, but are not visible because
  w is unmapped.  Unmapping a window will generate exposure events on windows that were formerly obscured by w.

  For more information on window mapping, see Volume One, Chapter 2, X Concepts.

Errors
  BadWindow
