863 * To create a standard colormap if one does not currently exist, or
864 * replace the currently existing standard colormap, use
865 * XmuLookupStandardColormap().
867 * Given a screen, a visual, and a property, XmuLookupStandardColormap()
868 * will determine the best allocation for the property under the specified
869 * visual, and determine the whether to create a new colormap or to use
870 * the default colormap of the screen. It will call XmuStandardColormap()
871 * to create the standard colormap.
873 * If replace is true, any previous definition of the property will be
874 * replaced. If retain is true, the property and the colormap will be
875 * made permanent for the duration of the server session. However,
876 * pre-existing property definitions which are not replaced cannot be made
877 * permanent by a call to XmuLookupStandardColormap(); a request to retain
878 * resources pertains to newly created resources.
880 * Returns 0 on failure, non-zero on success. A request to create a
881 * standard colormap upon a visual which cannot support such a map is
882 * considered a failure. An example of this would be requesting any
883 * standard colormap property on a monochrome visual, or, requesting an
884 * RGB_BEST_MAP on a display whose colormap size is 16.
