NAME
       strnlen - determine the length of a fixed-size string

SYNOPSIS
       #define _GNU_SOURCE

       #include 

       size_t strnlen(const char *s, size_t maxlen);

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

CONFORMING TO
       This function is a GNU extension.
