       colormap_windows_return
                 Returns the list of windows.

       count     Specifies the number of windows in the list.

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_win-
       dows argument.  The property is stored with a type of WINDOW and a for-
       mat of 32.  If it cannot intern the WM_COLORMAP_WINDOWS atom, XSetWM-
       ColormapWindows 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 identi-
       fiers stored in the WM_COLORMAP_WINDOWS property on the specified win-
       dow.  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 num-
       ber 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.
