Description
       The 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, 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, returns a zero status.  Otherwise, it returns a non-zero status.

       can generate and errors.

       The 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 for-
       mat 32, and the atom WM_COLORMAP_WINDOWS can be interned, sets the windows_return argument to a list of window identifiers, sets the
       count_return argument to the number of elements in list, and returns a non-zero status.	Otherwise, it sets neither of the return arguments
       and returns a zero status.  To release the list of window identifiers, use

       can generate a error.

Properties
