DESCRIPTION
The strnlen() function
returns the number of characters in the string pointed to by
s, excluding the
terminating null bye ('\0'), but at most maxlen. In doing this,
strnlen() looks only at the
first maxlen
characters at s and
never beyond s+maxlen.
RETURN VALUE
The strnlen() function
returns strlen(s),
if that is less than maxlen, or maxlen if there is no null byte
('\0') among the first maxlen characters pointed to by
s.
