    DescriptionThe  XcupGetReservedColormapEntries   function returns a list
    of colormap entries (pixels) that are reserved by the system. This list
    will, at a minimum, contain entries for the  BlackPixel and WhitePixel
    of the specified screen. Use  XFree   to free  colors_out.
    To minimize colormap
    flash, an application which installs its own private colormap should query
    the special colors by calling XCupGetReservedColormapEntries,   and can
    then store those entries (in the proper location) in its private colormap
    using  XCupStoreColors.
