cc [ flag ... ] file ... -lXext [ library ... ]
Status XcupGetReservedColormapEntries(Display *display,
int screen, XColor **colors_out, int *ncolors);
display Specifies the connection to the X server.
screen Screen number on the host server.

ncolors Returns the number of items in colors_out.
The 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.
