__u64 can't be formatted with %llu on all architectures. That's not true for uint64_t, where you have to use %lu on some architectures to avoid compiler warnings (and technically undefined behavior). There are preprocessor macros to get the expected format specifiers, but they are clunky. I don't know if the problem applies to uint32_t. It does happen with size_t and ptrdiff_t on 32-bit targets (both vary between int and long). Thanks, Florian
