Description

Pretty minor casting/printf things for FreeBSD port of libzfs. More or less, uint64_t and int64_t should use the printf() specifier %ju or %jd for i386/amd64 happiness.

uint64_t and int64_t should use the printf() specifier
%ju or %jd for i386/amd64 happiness.

Is there a specification for this ?

C99 section 7.8.1 defines PRId64 for formatting an int64_t (PRIu64 for a uint64_t).

I think, after more public review and comments, that this is "more appropriate" for the code in question. It simply looks like there's a few missing casts to longlong_t that need to be added. There's a bit of discussion about the validity of these casts in the first place and C99 does indeed specify a way to do this that is portable (see comment#2).
