What is close_all in asyncore?

Samia Ishaque

Overview

The asyncore module in Python lets you build a network of asynchronously communicating clients and servers using sockets. Since threads are no longer required, the implementation is much easier. Use the following code to import the asyncore module into your program:

import asnycore

The close_all function in the asyncore module is used to close all connections. To close one connection, we can use the close function defined in asyncore, but if multiple connections are present, we must use the close_all function.

Parameters

The function close_all takes no mandatory inputs as arguments.

Return value

The close_all function has no return value.

Example

Below is an example of how you can use the close_all function. This is a general example, as the close_all function can be called before running the loop for the asyncore module. Before calling the close_all function, you may establish a connection and handle their reads and writes.

import asyncore

#your code for establishing connections and handling their
# read and writes
asycnore.close_all()
asyncore.loop()
