Hello, I need a c binary heap implementation with a extended function that updates the priority of a node. I found some implementations with a decrease operation but I need both (increase and decrease). That's the implementation of the update function. The implementation must have siftup and siftdown function in order to compute the increase and decrease operations. Does anybody known any souce code that works fine? Thank you, Pascual.
