As other have pointed out, there is an snprintf.c implementation
in src/util. [...] it does support features not found in every
sprintf, such as %llu and %lld formats for 64-bit integers.
In trying to add LFS to the fileserver, I've needed to be able
to display integers that might be either 32- or 64-bit,
depending on compilation options. [...] The cleanest solution
I've found, and what I've implemented, is to make cast these
values to afs_intmax_t or afs_uintmax_t, which are guaranteed
to be correctly formatted using %lld or %llu, respectively,
whether or not the AFS_64BIT_ENV is set.
For what it's worth, freebsd-standards policy is to cast to
uintmax_t or u_intmax_t, and then use %ju or %jd to print.
(freebsd-standards is our project to follow posix/SUSv3
standards as closely as possible). Does afs_snprintf
implement %j?
I *think* it's true that %ll will not necessarily do the right
thing for values of type intmax_t, since it is explicitly for
long-long, while %j is explicitly for intmax_t. Obviously
those are often the same thing, but I suspect that they are
allowed to be different.
