[boost] Newbie question on asio and TCP/IP

Hi,

I'm writing program with asio from 1.35.0 to read the
data from a hardware device which sends data to my PC
to port 7000. The sample below fails on Windows with
exception code 10022, text "An invalid argument was
supplied".

Where's the fault? Can someone help please?

----------- sample code -------------
#include <iostream>
#include <boost/asio.hpp>

using boost::asio::ip::udp;

int main(int argc, char* argv[])
{
  try
  {
    boost::asio::io_service io_service;

    udp::endpoint sender_endpoint( udp::v4(), 7000 );

    udp::socket socket(io_service);
    socket.open( udp::v4() );

    char packet[1024];

    size_t len = socket.receive_from(
        boost::asio::buffer(packet), sender_endpoint);

    std::cout << "Works\n";
  }
  catch(const std::exception& e)
  {
    std::cerr << e.what() << std::endl;
  }
  return 0;
}
