fcup-smsend: fixed bug in the handling of -W with no dest address argument The original code checked for argv[optind+1] when argv[optind] is NULL; on most systems this bogus code gets the first line of the environment, which is clearly not what we are after. Fixed the code to check argc instead.

#include <sys/types.h>

u_char *
memset(buf, c, n)
	u_char *buf;
	int c;
	unsigned n;
{
	u_char *p = buf;

	for (; n; n--)
		*p++ = c;
	return buf;
}
