XcupStoreColors(3)			   X FUNCTIONS			       XcupStoreColors(3)

       XcupStoreColors - initialize shareable colormap entries at specific locations

       cc [ flag ... ] file ... -lXext [ library ... ]
       #include <X11/extensions/Xcup.h>

       Status XcupStoreColors(Display *display, Colormap colormap,
	      XColor *colors_in_out, int ncolors);

       display	 Specifies the connection to the X server

       colormap  Specifies the colormap

		 Specifies and returns the values actually used in the colormap

       ncolors	 Specifies the number of items in colors_in_out

       The 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 Direct-
       Color 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.
