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 characters pointed to by s.
CONFORMING TO
This function is a GNU extension.
