What are the best practices for using mutex in C++?

When using mutex in C++, it's important to minimize the scope of the lock, avoid deadlocks, and prefer RAII.

Can you explain what RAII means in this context?

RAII stands for Resource Acquisition Is Initialization. It ensures that resources are properly released when objects go out of scope.

What are some common mistakes to avoid with mutex?

Common mistakes include holding a lock for too long, forgetting to unlock, and using multiple locks without a clear order.

How can I test if my mutex implementation is correct?

You can use stress testing and concurrency testing tools to simulate multiple threads and check for race conditions.
