From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.

NAME

XDestroyWindow, XDestroySubwindows - destroy windows

SYNTAX

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

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

ARGUMENTS

display   Specifies the connection to the XWIN server.

w         Specifies the window.

DESCRIPTION

The XDestroyWindow function destroys the specified window as
well as all of its subwindows and causes the XWIN 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 des-
troyed.

XDestroyWindow can generate a BadWindow error.

The XDestroySubwindows function destroys all inferior win-
dows of the specified window, in bottom-to-top stacking
order.  It causes the XWIN server to generate a DestroyNo-
tify event for each window.  If any mapped subwindows were
actually destroyed, XDestroySubwindows causes the XWIN
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.
