How can I debug mutex issues in my C program?

Debugging mutex issues often involves checking for deadlocks, race conditions, and ensuring proper lock usage. What specific problem are you facing?

I'm getting a deadlock when two threads try to acquire the same mutex.

Deadlocks occur when two or more threads are waiting for each other to release locks. You can use tools like Valgrind or GDB to trace the lock acquisition. Have you tried logging the lock acquisition order?

No, I haven't. How would I do that?

You can add logging statements before each lock acquisition and release. This way, you can see the order in which locks are being acquired and identify any circular wait conditions.

That sounds helpful! Are there any best practices to avoid these issues?

Yes, some best practices include always acquiring locks in a consistent order, using timeouts for lock attempts, and minimizing the time locks are held. Would you like more details on any of these?
