C2011 has char *gets_s(char *s, rsize_t n);

It discards the \n, but does not discard the rest of the line, so 
you can't tell the difference between a line that was exactly the 
maximum length (followed by a \n which is discarded) or a line 
that was too long.  fgets() can tell the difference, however.
