What are some thread safety techniques in C++11?

C++11 introduced several features for thread safety, including mutexes, locks, and atomic operations. Would you like to know more about any specific technique?

Can you explain how mutexes work?

Mutexes are used to protect shared data from being accessed by multiple threads simultaneously. You lock a mutex before accessing shared data and unlock it afterward.

What is the difference between std::mutex and std::recursive_mutex?

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

Are there any performance considerations when using locks?

Yes, using locks can introduce overhead and potentially lead to contention. It's important to minimize the time a lock is held and consider lock-free programming when performance is critical.
