What is the bit size of long on 64-bit Windows? http://stackoverflow.com/questions/384502/what-is-the-bit-size-of-long-on-64-bit-windows integers int32_t 32 bit integers int64_t 64 bit integers uintptr_t unsigned integers big enough to hold pointers intmax_t biggest.. with system types which might be different . There is an intptr_t type a signed integer type for holding pointers you should plan.. it or only using it as the result of a subtraction of two uintptr_t values ptrdiff_t . But as the question points out in disbelief..
