The
strnlen()
function returns the number of characters in the string
pointed to by s, not including the terminating aq\0aq character,
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 aq\0aq character among the first
maxlen characters pointed to by s.
