EOF in async_read() in boost::asio

When the async_read_some() returns an exception of EOF does it mean the server stopped sending data or does it mean the connection is closed. I'm having this confusion as I cant find a method to know if the client has received all data from server.

TcpClient.GetStream().DataAvailable returns false, but stream has more data

So, it would seem that a blocking Read() can return before it is done receiving all of the data being sent to it. In turn we wrap the Read() with a loop that is controlled by the DataAvailable value from the stream in question. The problem is that…
