const eventNames = process.eventNames();
eventNames.forEach((eventName) => {
    const listeners = process.listeners(eventName);
    console.log(`Event: ${eventName}`);
    console.log(`Listeners:`);
    listeners.forEach((listener, index) => {
        console.log(`  Listener ${index + 1}: ${listener.toString()}`);
        // Note: listener.toString() might not always give meaningful information,
        // especially for native code. It's more useful for debugging simple listeners.
    });
});

// cleanup sigint
process.removeAllListeners('SIGINT');

// create new listener
process.on('SIGINT', () => {console.log('stuff'); });
