Suppose there is a service in /etc/services that has a different port number for tcp than for udp: fooserv 50001/tcp fooserv 50002/udp You're saying that getaddrinfo will return the same port number in all of the returned structures? Won't that mean that one of the port numbers is wrong? That seems broken if so... If that's not the case, then I think we need to at least set the ai_protocol in the hints. -- Jeff Layton <jlayton@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
