Convert from CIE to RGB with Xlib

Hello peoples! I'm new programmer in *NIX, and I need in method of converting from CIE colour format to RGB colour format with Xlib. I don't find this method in Internet, help me please. Sorry, my english is bad.

Well if you've searched the XLib API for something to do it, and found nothing, then you're going to have to write to code yourself (or find some standalone code to adapt for your use).

Here's the maths.
Computer RGB colour space.
