How do you use the Xlib function XQueryColor(s) in X11 R2?

More specifically, why doesn't this function return "Status"?

I assume that this function waits for a reply. Otherwise, how can you
be sure that your XColor structures have been filled in. So what
happens when an error occurs? The Xlib error handler kicks in, of
course. But determining that an error occurred via the error handler
in client code is not very convenient.

So why not just return a "Status" (like most other "query" type
functions)?  Then it's easy to tell what happened.

If I have missed something obvious here, let me sheepishly appolgize
in advance.
