  You can pass them using boost::bind:
   socket_.async_read_some(boost::asio::buffer(data_, max_length),
        boost::bind(&session::handle_read, this,
          boost::asio::placeholders::error,
          boost::asio::placeholders::bytes_transferred,
          boost::ref(largeObject)));

  Where:
  void session::handle_read(const boost::system::error_code& error, size_t
bytes_transferred, LargeObject & largeObject)
  {
     ......
  }

Best Regards,
  Sergei
