Ok, so now I need to ask another dumb question.
How do you do this in the kernel?
(I can see them defines in <machine/_inttypes.h>, but including that
doesn't help, which isn't surprising since PRIu64 is in a string
and won't be recognized as a macro.)
Oh, and is intmax_t going to be int64_t on all arches?
Thanks, rick
