What are C++ thread library locks?

Can you explain what C++ thread library locks are?

C++ thread library locks are synchronization mechanisms that help manage access to shared resources in multithreaded programs.

How do I use mutex locks in C++?

You can use std::mutex from the <mutex> header. To lock a mutex, you call lock() and to unlock, you call unlock().

What happens if I forget to unlock a mutex?

Forgetting to unlock a mutex can lead to deadlocks, where threads are waiting indefinitely for the mutex to be released.

Are there other types of locks in C++?

Yes, besides mutexes, C++ also provides std::recursive_mutex, std::timed_mutex, and std::shared_mutex for different use cases.
