Forget what you've read. The C standard and POSIX make no requirements about the sizeof(void*) vs. sizeof(int) or sizeof(long). Making assumptions that they are equal is a sign of broken code; just because it HAPPENS to work on your 32bit machine does not make it right. Pointers are even allowed to be smaller than ints, although good luck finding an actual machine with those semantics. The standards do, however, make a requirement that sizeof(void*) == sizeof(intptr_t), so that you can safely convert a pointer to an integer type. - -- Life is short - so eat dessert first!
