	What is the big deal here? How about:

extern	int	strlen();
static	int	_nstrnlen_;	/* to avoid two calls to strlen() */
#define	strnlen(S,N)	( (_nstrnlen_=strlen(S)) > (N) ? (N) : _nstrnlen_ )

	or:

int	strnlen(s,n)
char	*s;
int	n;
{
	char	*c;
	int	len = 0;

	for ( c=s; *c && (len<n); c++, len++ )
		;
	return(len);
}

	Was it a joke? Did I miss something?
