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

DIAGNOSTICS
