An example of an AI chatbot conversation about signal handling best practices in programming.
What are the best practices for signal handling in programming?
Best practices for signal handling include using signal masks, avoiding complex operations in signal handlers, and ensuring thread safety.
Can you explain why avoiding complex operations is important?
Avoiding complex operations is crucial because signal handlers can interrupt the flow of your program, leading to inconsistent states or deadlocks.
What should I do if I need to perform a complex operation?
If you need to perform a complex operation, consider setting a flag in the signal handler and handling the operation in the main program flow.
Are there specific signals I should be more cautious about?
Yes, signals like SIGKILL and SIGSTOP cannot be caught or ignored, while others like SIGINT and SIGTERM can be handled more flexibly.
