Comparing Thread Safety Techniques in C++11

What are the main thread safety techniques introduced in C++11?

C++11 introduced several techniques for thread safety, including mutexes, locks, and atomic operations.

Can you explain how mutexes work in C++11?

Mutexes are used to protect shared data from being accessed by multiple threads simultaneously, preventing data races.

What are the differences 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.

When should I use atomic operations instead of mutexes?

Use atomic operations for simple data types when you need lock-free performance, as they can be faster than mutexes.
