What is thread safety in the C++ Standard Library?

What is thread safety in the C++ Standard Library?

Thread safety in the C++ Standard Library refers to the ability of library components to be safely used by multiple threads simultaneously without causing data races or inconsistencies.

Can you give examples of thread-safe components in the C++ Standard Library?

Sure! Examples include std::mutex, std::lock_guard, and std::atomic. These help manage concurrent access to shared resources.

How do I ensure my own classes are thread-safe?

To ensure your classes are thread-safe, you can use synchronization mechanisms like mutexes, avoid shared mutable state, and design your classes to be immutable when possible.

What are common pitfalls to avoid when dealing with thread safety?

Common pitfalls include neglecting to lock shared resources, using non-atomic operations on shared data, and creating deadlocks by improper lock ordering.
