[Boost-users] [getting IP-header]How do I get the IP-header information

29 Oct 2009

      Hello,

I'm trying to get the IP-header information from an IP-message sent
using boost. I can get the message itself by using:

void Receiver::wait_for_packet() {

    socket.async_receive_from(boost::asio::buffer(receive_buffer),
remote_endpoint, boost::bind(
            &Receiver::handle_packet, this, boost::asio::placeholders::error,
            boost::asio::placeholders::bytes_transferred));
}

void Receiver::handle_packet(const boost::system::error_code& error,
int bytes_transferred) {
    if (error) {
        //throw boost::system::system_error(error);
    }

    std::string message;

        for (int i = 0; i < bytes_transferred; i++) {
            message += receive_buffer[i];
        }

    std::string payload(message);

    Packet packet;
    packet.set_payload(payload);

    listener->new_packet_received(packet);

    wait_for_packet();
}

Where "message" is the body of the sent stuff. But how do I get to the
IP-header things?
I've been looking in
doc/html/boost_asio/example/serialization/connection.hpp, but do not
really get what to do.
