(usagi-users 02365) Re: IPv6 replcement for sendto() ?

[Mitsuru KANDA / 神田 充 <mk@xxxxxxxxxxxxxx>]

You can just use 'to' by casting sockaddr_storage structure.
(sockaddr_in{} is small for IPv6 address.)



getaddrinfo()-send*() combination is more useful.
(It can conceal IP version.)

struct addrinfo hints, *res, *res0;
getaddrinfo(host, service, &hints, &res0);
...
for (res=res0; res; res = res->ai_next) {
	s = socket(res->ai_family, res->ai_socktype,
					res->ai_protocol);
	...

	sendto(s, buf, n, 0, res->ai_addr, res->ai_addrlen);
	....
}
