poker-eval is a C library to evaluate poker hands. The result of the evalution for a given hand is a number. The general idea is that if the evalution of your hand is lower than the evaluation of the hand of your opponent, you lose. Many poker variants are supported (draw, holdem, omaha, etc.) and more can be added. poker-eval is designed for speed so that it can be used within poker simulation software using either exhaustive exploration or Monte Carlo.
