How can I debug a deadlock in my C program?

How can I debug a deadlock in my C program?

To debug a deadlock, you can use tools like gdb or valgrind. Have you tried using any debugging tools?

I haven't used gdb yet. How do I set it up?

You can install gdb using your package manager. Once installed, compile your program with the -g flag to include debug symbols.

What should I look for in gdb to identify the deadlock?

In gdb, you can use the thread apply all bt command to get a backtrace of all threads. This will help you see where each thread is stuck.

Thanks! Are there any common patterns that lead to deadlocks?

Yes, common patterns include circular wait, hold and wait, and no preemption. Avoiding these can help prevent deadlocks.
