Maybe somebody could tell me if there is a difference between:
snprintf(buf, sizeof(buf), "%s", some_string);
and
strncpy(buf, some_string, sizeof(buf));
buf[sizeof(buf) - 1] = 0;

That should do essentially the same thing, but maybe I'm missing
something. I'd like to encourage one way doing this.

BTW. We check in configure script if snprintf() produces
null-terminated string and if not, we provide working version.

take care,
