Well, as I said, there are probably libraries out there. boost provides them for C++, they must exist for C as well. In any case, if you are out for performance, avoid the modulo. If you want a fixed limit, I suggest providing a typedef to an int, and an add and get function. Use the fact that 2^18 % 12 == 0 and work with bits 18, 19, and 20 to make automatic use of the integer limit for rollover.
