How can I debug threading issues in C++?

Debugging threading issues in C++ can be challenging. You can start by using tools like Valgrind or ThreadSanitizer.

What specific problems should I look for when debugging?

Look for race conditions, deadlocks, and resource contention. These are common issues in multithreaded applications.

Can you explain how to identify a deadlock?

To identify a deadlock, check if two or more threads are waiting for each other to release resources. Tools like Visual Studio can help visualize thread states.

Are there any best practices to avoid these issues?

Yes, use mutexes wisely, avoid global variables, and consider using higher-level abstractions like thread pools.
