Error Control C Exit 572 (0x23C): How to Fix it

When developing you may encounter the following code: ERROR_CONTROL_C_EXIT. Many users don’t know what this code represents, so let’s dive deeper and see what it does.

How can I fix ERROR_CONTROL_C_EXIT?

1. Modify the code

1. Open your code.
2. Next, use the following code
   import signal
import sys
def handle_sigint(signum, frame):
print("\nCTRL+C detected. Performing cleanup...")
    # Add any cleanup logic here
  sys.exit(0)  # Exit gracefully

signal.signal(signal.SIGINT, handle_sigint)

while True:
    print("Running... Press CTRL+C to stop.")
   
3. Save changes.

2. Log the interruption

1. Open your code.
2. Adjust it like this:
   import signal
import sys
import logging

logging.basicConfig(filename='app.log', level=logging.INFO)
def handle_sigint(signum, frame):
    logging.info("Application terminated by CTRL+C")
    sys.exit(0)

signal.signal(signal.SIGINT, handle_sigint)

while True:
    print("Running... Press CTRL+C to stop.")
   
3. Save changes.

3. Use proper cleanup

1. Open your code again.
2. Modify it so it uses this logic:
   import signal
import sys

file = open('example.txt', 'w')

def handle_sigint(signum, frame):
    print("Closing file and exiting...")
    file.close()
    sys.exit(0)

signal.signal(signal.SIGINT, handle_sigint)

while True:
    file.write("Writing data...\n")
   
3. Save changes.

4. Additional tips

1. Set a proper restart policy if the application terminates.
2. Handle logging of unexpected exits.
3. Inform users that this keyboard shortcut exits most command line applications.

In most cases, ERROR_CONTROL_C_EXIT doesn’t need additional handling, since it’s a regular occurrence when a user uses a keyboard shortcut to exit the code.

Keep in mind that this error sometimes comes with the following message: 572 (0x23C) {Application Exit by CTRL+C} The application terminated as a result of a CTRL+C.

This is just one of many issues you can encounter, and recently we wrote about Subprocess-exited-with-error and Kernel Stack Locked At Exit, so don’t miss them for more information.
