## Synopsis

    #include <X11/extensions/Xcup.h>

    Status XcupStoreColors(Display *display, Colormap colormap,XColor *colors_in_out,
    int ncolors);ArgumentsdisplaySpecifies the connection to the X server colormapSpecifies
    the colormap colors_in_outSpecifies and returns the values actually used
    in the colormap ncolorsSpecifies the number of items in colors_in_out DescriptionThe
     XcupStoreColors   function changes the colormap entries of the pixel values
    in the pixel members of the XColor structures. The colormap entries are
    allocated as if an AllocColor has been used instead, i.e. the colors are
    read-only (shareable). XcupStoreColors   returns the number of colors that
    were successfully allocated in the colormap.
    A  Value   error is generated
    if a pixel is not a valid index into the colormap. A BadMatch   error is
    generated if the colormap does not belong to a GrayScale, PseudoColor,
    or DirectColor visual.
    Applications which allocate many colors in a screen's
    default colormap, e.g. a color-cube or a gray-ramp, should allocate them with
     XCupStoreColors.   By using XCupStoreColors the colors will be allocated
    sharable (read-only)  and any other application which allocates the same
    color will share that  color cell.
