                                6 January 1993


 Name

    XDestroyWindow - destroy windows

 Syntax


    XDestroyWindow(display, w)
          Display *display;
          Window w;

    XDestroySubwindows(display, w)
          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 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 automat-
    ically.  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.

 Diagnostics


    ``BadWindow''  A value for a Window argument does not name a defined Win-
                   dow.
