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

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

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

Can you explain when to use each type of lock?

Use mutexes when you need to ensure that only one thread can access a resource at a time. Use readers-writer locks when you have many threads reading data and fewer threads writing, as it improves performance.

What are the potential drawbacks of using readers-writer locks?

The main drawbacks include complexity and the potential for writer starvation, where writers may be delayed if there are continuous read requests.

Are there any scenarios where a mutex would be preferred over a readers-writer lock?

Yes, if the critical section is short or if the overhead of managing readers-writer locks outweighs their benefits, a mutex is preferred.
