I know this is slightly off the normal subject matter, but I'm getting
desperate, so here goes:

I need to create a read/write colormap for a Motif program.   The
program offers the user the option of selecting colors via three scroll
bars (RGB values 0 to 64k).  The color selected by the user should then
be stored in the colormap for use by the program.

Here's what I'm trying to do:

def_colormap = DefaultColormap(mydisplay, DefaultScreen(mydisplay);

for (i=0; i < NUMCOLORS; i++)      /* NUMCOLORS = 256 */
   {
     Colors[i].pixel = i;
     Colors[i].flags = DoRed | DoGreen | DoBlue;
   }

XQueryColors(mydisplay, def_colormap, Colors, NUMCOLORS);
my_colormap = XCreateColormap(mydisplay, DefaultRootWindow(mydisplay),
                         DefaultVisual(mydisplay,
DefaultScreen(mydisplay)),
                         AllocAll);
XStoreColors(mydisplay, my_colormap,Colors,NUMCOLORS);
// XInstallColormap(mydisplay, my_colormap);

Any suggestions would be much appreciated.
