[NSWI004] simple_printf with pointers

[Petr Tůma]

Hi Krisztian,

what data loss exactly do you observe and what platform does that happen on ? The C language standard defines uintptr_t, an integer large enough to store a pointer (https://stackoverflow.com/questions/1845482/what-is-uintptr-t-data-type), so it is safest to use that - however, if you use a typical machine then both void * and unsigned long int would be 8 bytes and your problem is probably somewhere else.
