boost::asio UDP broadcasting

Question

I want to broadcast UDP messages to all computers in a local network using boost::asio. Working through the examples I came up with

try {
    s         


        

Answer 1

Try the following code snippet to send a UDP broadcast, utilizing the ba::ip::address_v4::broadcast() call to get an endpoint:

    bs::error_code error;
    ba::ip::udp::socket socket(_impl->_ioService);

    socket.open(ba::ip::udp::v4(), error);
    if (!error)
    {
        socket.set_option(ba::ip::udp::socket::reuse_address(true));
        socket.set_option(ba::socket_base::broadcast(true));

        ba::ip::udp::endpoint senderEndpoint(ba::ip::address_v4::broadcast(), port);            

        socket.send_to(data, senderEndpoint);
        socket.close(error);
    }
