What are some thread safety techniques in C++?

What are some thread safety techniques in C++?

Thread safety in C++ can be achieved using techniques like mutexes, locks, and atomic operations. Would you like to know more about any specific technique?

Can you explain how mutexes work?

Mutexes, or mutual exclusions, are used to protect shared data from being accessed by multiple threads simultaneously. They allow only one thread to access the resource at a time.

What are the differences between mutexes and locks?

Mutexes are a low-level synchronization primitive, while locks are higher-level abstractions that often use mutexes internally. Locks can provide additional features like deadlock detection.

Are there any performance considerations when using these techniques?

Yes, using thread safety techniques can introduce overhead. It's important to balance safety and performance, often by minimizing the scope of locks.
