page 277:
Specifies that a following d, i, o, u, x, or X conversion specifier
applies to an intmax_t or uintmax_t argument; or that a following n
conversion specifier applies to a pointer to an intmax_t argument.

I prefer casting to (u)intmax_t and using "j", because that makes the
code ready for 128 bit.
But if you prefer I can convert to using the fixed size macros.
Thanks!
