The problem here is that we don't know what you don't understand. If you're casting a pointer to an (32-bit) int, then if you are on a 64-bit system, there will be overflow and some information will be lost. If you're on a 32-bit system then there won't be a problem. This seems obvious: what's the problem? Andrew.
