Use streambuf as buffer for boost asio read and write

Question

I\'m using this code for reading

  socket_.async_read_some(boost::asio::buffer(data_, max_length),
        boost::bind(&session::handle_read, this,

You need to get a mutable_buffers_type from the streambuf to use as your first parameter to async_read_some.

  boost::asio::streambuf streamBuffer;
  boost::asio::streambuf::mutable_buffers_type mutableBuffer =
      streamBuffer.prepare(max_length);
  socket_.async_read_some(boost::asio::buffer(mutableBuffer),
        boost::bind(&session::handle_read, this,
        boost::asio::placeholders::error,
        boost::asio::placeholders::bytes_transferred));

See the asio documentation here and here for more info.
