WebThe Push flag tells the receiver's network stack to "push" the data straight to the receiving socket, and not to wait for any more packets before doing so. The Push flag usually means that data has been sent whilst overriding an in-built TCP efficiency delay, such as Nagle's Algorithm or Delayed Acknowledgements. WebUpon a message from the client, the recv ( ) function returns the number of bytes read. If it returns the zero, means the connection is terminated by the peer with a FIN and FIN Ack.
