What are the best practices for using mutexes in programming?

When using mutexes, it's important to minimize the time a mutex is held to avoid contention. Always lock the mutex as late as possible and unlock it as early as possible.

Can you explain why minimizing lock time is important?

Minimizing lock time reduces the chances of deadlocks and allows other threads to access shared resources more efficiently, improving overall performance.

Are there any common mistakes to avoid when using mutexes?

Yes, common mistakes include forgetting to unlock a mutex, locking the same mutex multiple times in the same thread, and using mutexes in a way that can lead to deadlocks.

What alternatives to mutexes can be used for thread synchronization?

Alternatives include using read-write locks, semaphores, or even higher-level abstractions like concurrent data structures.
