Hello,
�
I have a tcp server coded with python and my packets include a 2 bytes header 
which is just the length of the following data. The problem is how can I be 
sure I received 2 bytes and not just one byte. In Qt, I use bytesAvailable 
function. However, here I just use sock.recv(2) but it can fetch less than 2 
since the parameter is the maximum length. Do we have any method?
