I don't understand how can flags to getaddrinfo(3) affect source
address selection. where does it take effect in the following code?
itojun
error = getaddrinfo(host, serv, &hints, &res);
s = -1;
for (ai = res; ai; ai = ai->ai_next) {
s = socket(ai->ai_family, ai->ai_socktype, ai->ai_protocol);
if (s < 0)
continue;
if (connect(s, ai->ai_addr, ai->ai_addrlen) < 0) {
close(s);
s = -1;
continue;
}
break;
}
if (s < 0)
exit(1);
/* we have a socket */
