A protocol stack, generally supplied by the running procedure (instead of being a individual library, For illustration), is really a set of providers that let processes to speak more than a community utilizing the protocols the stack implements.
The server’s message class is in libserver.py, which can be Component of the resource code you downloaded before. You may as well down load the code by clicking the hyperlink beneath:
The following example demonstrates a similar HTTP GET situation, utilizing Task-dependent asynchronous APIs, even though also forwarding a CancellationToken into the asynchronous approaches, creating How to fit outside socket the entire operation cancellable.
Socket are generally used in consumer server applications. The server results in a socket, attaches it into a network port addresses then waits with the customer to Speak to it.
That section didn’t point out the columns Recv-Q and Deliver-Q in the instance output.
