     DESCRIPTION
          The XSetWMColormapWindows function replaces the
          WM_COLORMAP_WINDOWS property on the specified window with
          the list of windows specified by the colormap_windows
          argument.  It the property does not already exist,
          XSetWMColormapWindows sets the WM_COLORMAP_WINDOWS property
          on the specified window to the list of windows specified by
          the colormap_windows argument.  The property is stored with
          a type of WINDOW and a format of 32.  If it cannot intern
          the WM_COLORMAP_WINDOWS atom, XSetWMColormapWindows returns
          a zero status.  Otherwise, it returns a nonzero status.

          XSetWMColormapWindows can generate BadAlloc and BadWindow
          errors.

          The XGetWMColormapWindows function returns the list of
          window identifiers stored in the WM_COLORMAP_WINDOWS
          property on the specified window.  These identifiers
          indicate the colormaps that the window manager may need to
          install for this window.  If the property exists, is of type
          WINDOW, is of format 32, and the atom WM_COLORMAP_WINDOWS
          can be interned, XGetWMColormapWindows sets the
          windows_return argument to a list of window identifiers,
          sets the count_return argument to the number of elements in
          the list, and returns a nonzero status.  Otherwise, it sets
          neither of the return arguments and returns a zero status.
          To release the list of window identifiers, use XFree.

          XGetWMColormapWindows can generate a BadWindow error.

     PROPERTIES
          WM_COLORMAP_WINDOWS
                    The list of window IDs that may need a different
                    colormap from that of their top-level window.

     DIAGNOSTICS
          BadAlloc  The server failed to allocate the requested
                    resource or server memory.

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