Subject: Properly handle *snprintf() errors
X-Git-Url: https://git.xinqibao.xyz/slstatus.git/commitdiff_plain/c83b388a3f8f7a8c8d5a5cfddb6ab397005371a1?ds=sidebyside;hp=c83b388a3f8f7a8c8d5a5cfddb6ab397005371a1

Properly handle *snprintf() errors

Posix guarantees that the resulting string is null-terminated, even if
we have an overflow. Instead of doing what has already been done,
properly warn when there has been an error or overflow, so the user can
do something about it.
