What are the best practices for using mutexes in programming?

When using mutexes, it's important to keep the following best practices in mind: 1. Keep the locked section short. 2. Avoid nested locks. 3. Use try-locks when possible. 4. Always unlock in the same scope. 5. Document your locking strategy.

Can you explain why keeping the locked section short is important?

Keeping the locked section short minimizes the time that other threads are blocked, which improves overall performance and reduces the risk of deadlocks.

What are nested locks and why should I avoid them?

Nested locks occur when a thread tries to acquire a lock that it already holds. This can lead to deadlocks if not managed carefully, as it can create a situation where two or more threads are waiting on each other indefinitely.

What is a try-lock?

A try-lock is a non-blocking way to acquire a mutex. It attempts to lock the mutex and returns immediately, allowing the thread to continue executing if the lock is not available.
