What are the different types of mutexes in C++?

In C++, there are several types of mutexes, including std::mutex, std::recursive_mutex, std::timed_mutex, and std::shared_mutex. Each serves different purposes.

Can you explain the difference between std::mutex and std::recursive_mutex?

Sure! std::mutex allows only one thread to own the mutex at a time, while std::recursive_mutex allows the same thread to lock it multiple times without causing a deadlock.

When should I use std::shared_mutex?

You should use std::shared_mutex when you want to allow multiple threads to read shared data simultaneously while still providing exclusive access for writing.

Are there any performance considerations I should be aware of?

Yes, using shared_mutex can improve performance in read-heavy scenarios, but it may introduce overhead due to managing shared access.
