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.
