To run this example, follow these steps:
-
Start the server in one terminal:
python server.py -
Get the server's process ID (PID). The server process will print the PID when launched
-
Start the client in another terminal:
python client.py <server_pid>where<server_pid>is the PID of the server process.
The client can send SIGUSR1 or SIGUSR2 signals to the server, and the server will respond accordingly. Please note that this is a basic example, and in a real-world scenario, you would likely implement more robust error handling and message passing logic.
The signal handlers have logic to add information to a global array depending on what signal is received.
