DESCRIPTION
The strnlen() function
returns the number of bytes in the string pointed to by
s, excluding the
terminating null byte ('\0'), but at most maxlen. In doing this,
strnlen() looks only at the
first maxlen bytes 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 bytes pointed to by
s.
