utf8proc_ssize_t

[Matthew-Jemielity]

Hi,

If you're defining utf8proc_ssize_t as several different types according to platform, could you also have something like UTF8PROC_SSIZE_MIN, UTF8PROC_SSIZE_MAX, so it would be easier to have some safe conversion from size_t to it? This is mostly because of utf8proc_iterate using utf8proc_ssize_t strlen.

Regards,

Sure, we could define UTF8PROC_SSIZE_MAX ; a PR would be welcome.

utf8proc_ssize_t is a signed type that should be the same size as size_t on all known platforms.
So, the only time it would be not safe to convert would be if the length is ≥ 2^(n-1) on an n-bit platform. On a 64-bit platform this will never happen for any real string buffer.
