Hello list,
Could someone please shed some light on this subject. It seems that me read handler keeps on being called even when there has been no data transferred...
switch(error.value()) { case boost::system::posix_error::success: { c = new client();
socket.async_receive( boost::asio::buffer( buffer ),boost::bind( &client::handle_read, this, boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred ) );
Try changing this to use socket.async_read_some instead of async_receive.
Regards - michael
:D, just tried it - still no luck. I am invesigating if I am calling the buffer correctly. It seems that after the call to async_receive/async_read_some that there is still data pending for me to read... IE I never seem to get the data placed inside the std::vector correctly.
Are you saying that the handler is constantly getting called with bytes_transferred = 0? What is contained inside your buffer object? If your buffer has a size of 0, then this seems like it would cause the problem. Also, do you mean that for a single invocation of async_receive(), the handler is getting called multiple times? Or that for each call to async_receive, the handler gets called once with bytes_transferred=0? Is there an error code?
