Anyone can answer my question? 回答1: getnameinfo is what you want. getnameinfo((sockaddr*)&addr, sizeof(addr), hostname, sizeof(hostname), NULL, NULL, 0); 回答2: #include<asio.hpp> #include<exception> #include<iostream> int main() { try { asio::io_service io_service; asio::ip::udp::resolver rsv(io_service); for(const auto &ele : rsv.resolve(asio::ip::udp::endpoint(asio::ip::address_v4({192,168,1,163}),0))) { std::cout<<ele

I can only find boost::asio::ip::multicast::outbound_interface for IPPROTO_IP/IP_MULTICAST_IF, I tried but failed. Is there any way to make boost::asio::ip::multicast work without calling c-level setsockopt? boost::asio::ip::udp::endpoint listen_endpoint( listen_address, multicast_port); socket_.open(listen_endpoint.protocol()); socket_.set_option(boost::asio::ip::udp::socket::reuse_address(true)); socket_.bind(listen_endpoint); // Join
