Just FYI -- there are macros for the fixed-length types, e.g.:

    printf("U32: %" PRIu23 ", U64: " PRId64, (uint32_t)1, (int64_t)2);

Perhaps not as handy as %u32 or %s64, but it's here.

Yeah, and the issue is with those macros exactly. It makes writing code on them really damn annoying and it relies on C constant string concatenation, breaks the flow quite a lot.

Which is why I usually convert to intmax_t or uintmax_t, or to some type that I know is wide enough:

    uint64_t foo = ...;
    printf("foo = %ju\n", (uintmax_t)foo);
    /* OR */
    printf("foo = %llu\n", (unsigned long long)foo);

I think what emilfihlman means is those macros are hard to remember and clumsy to use - which you might agree with when I point out you made two mistakes in two usages :-p
