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

SYNOPSIS
       #include <string.h>

       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.
