What are the differences between mutex and reader-writer locks?

What are the differences between mutex and reader-writer locks?

Mutexes are used to ensure exclusive access to a resource, while reader-writer locks allow multiple readers or one writer.

When should I use a reader-writer lock instead of a mutex?

Use a reader-writer lock when you have many read operations and few write operations, as it improves concurrency.

Can you give an example of when a mutex would be more appropriate?

A mutex is better when you need to protect a resource that is frequently modified, ensuring exclusive access.

Are there any downsides to using reader-writer locks?

Yes, they can introduce complexity and potential for writer starvation if not managed properly.
