With C++ code, I tried to setsockopt for ipv6 TTL by:
int ttl = 8;
ret = setsockopt(skt, IPPROTOIPV6, IPV6UNICASTHOPS, &ttl, (socklent) sizeof(ttl));
I tried every option(such as sizeof(&ttl) still return errno 22, invalid argument.
sizeof(ttl) is 4 in this case.
Is this the right way to set IPV6 outgoing packet TTL? What is wrong here.
Same code for iOS works fine.
