c++ - udp broadcast using boost::asio under windows -


i'm having problems udp broadcast subsection of application. using boost 1.62.0 under windows 10. 

void test_udp_broadcast(void) {   boost::asio::io_service io_service;   boost::asio::ip::udp::socket socket(io_service);   boost::asio::ip::udp::endpoint remote_endpoint;    socket.open(boost::asio::ip::udp::v4());   socket.set_option(boost::asio::ip::udp::socket::reuse_address(true));   socket.set_option(boost::asio::socket_base::broadcast(true));   remote_endpoint = boost::asio::ip::udp::endpoint(boost::asio::ip::address_v4::any(), 4000);    try {     socket.bind(remote_endpoint);     socket.send_to(boost::asio::buffer("abc", 3), remote_endpoint);   } catch (boost::system::system_error e) {     std::cout << e.what() << std::endl;   } }

i receive: send_to: requested address not valid in context catch.

i've attempted change endpoint any() broadcast(), throws same error on bind().

i program under linux, , code works on normal target. i'm scratching head i'm doing wrong here. can give me poke in right direction?

i believe want bind socket local endpoint any() (if wish receive broadcast packets - see this question), , send remote endpoint using broadcast() (see this question).

the following compiles me , not throw errors:

void test_udp_broadcast(void) {   boost::asio::io_service io_service;   boost::asio::ip::udp::socket socket(io_service);   boost::asio::ip::udp::endpoint local_endpoint;   boost::asio::ip::udp::endpoint remote_endpoint;    socket.open(boost::asio::ip::udp::v4());   socket.set_option(boost::asio::ip::udp::socket::reuse_address(true));   socket.set_option(boost::asio::socket_base::broadcast(true));   local_endpoint = boost::asio::ip::udp::endpoint(boost::asio::ip::address_v4::any(), 4000);   remote_endpoint = boost::asio::ip::udp::endpoint(boost::asio::ip::address_v4::broadcast(), 4000);    try {     socket.bind(local_endpoint);     socket.send_to(boost::asio::buffer("abc", 3), remote_endpoint);   } catch (boost::system::system_error e) {     std::cout << e.what() << std::endl;   } }
