When should I use mutexes instead of semaphores?

Mutexes are used for exclusive access to a resource, while semaphores can allow multiple accesses. It depends on your needs.

Can you give me an example of when to use each?

Sure! Use a mutex when only one thread should access a critical section at a time. Use a semaphore when you want to limit access to a resource, like allowing up to 3 threads.

What are the performance implications of using one over the other?

Mutexes generally have lower overhead than semaphores, but semaphores can be more flexible for managing multiple threads.

Are there any scenarios where using both is beneficial?

Yes, you might use a mutex to protect a shared resource and a semaphore to control access to a pool of resources.
