Bon, pour les printfs en C:
#include <inttypes.h>
#define PRIu8 "hu"
#define PRId8 "hd"
#define PRIx8 "hx"
#define PRIu16 "hu"
#define PRId16 "hd"
#define PRIx16 "hx"
#define PRIu32 "u"
#define PRId32 "d"
#define PRIx32 "x" // x -> number in hexadecimal
#define PRIu64 "llu" // or possibly "lu"
#define PRId64 "lld" // or possibly "ld"
#define PRIx64 "llx" // or possibly "lx"| Syntax | Description |
|---|---|
| %zu | size_t |
| %d / %i | int |
| %u | unsigned int |

Finalement, pourquoi on ne mets pas toujours PRIxxx, ça serait plus explicite ...
