You can get tcp measured round trip time from tcp_info with struct tcp_info info; socklen_t len = sizeof(info); getsockopt(sock, IPPROTO_TCP, TCP_INFO

You can get tcp measured round trip time from tcp_info with struct tcp_info info; socklen_t len = sizeof(info); getsockopt(sock, IPPROTO_TCP, TCP_INFO, &info, &len); tcp_info varies by OS and version, but I think tcpi_rtt is well supported.
