我以为我在下面的例子中找到了答案,但并不完全.

boost::asio::ip::udp::socket socket(io_service); 
...
boost::asio::ip::address_v4 local_interface =
    boost::asio::ip::address_v4::from_string("1.2.3.4");
boost::asio::ip::multicast::outbound_interface option(local_interface);
socket.set_option(option);

如何映射eth0到适当的outbound_interface选项？
