Nope. If I understand you, this would require a protocol extension to do right. Another feature that I would really appreciate is to be able to find out just how many colors are available in a colormap (at least approximately, given asynchronicity) without having to call XAllocColorCells() multiple times or having the call fail until my request fits. Am I missing something here, too? This has also been asked about before. There is no support for this. The only thing you are missing is that, unless you grab the server, the answer you get back could be useless (either too large or too small) by the time you get around to allocating.
