What is thread safety in C++ standard library?

What is thread safety in the C++ standard library?

Thread safety in C++ means that a piece of code can be safely called from multiple threads simultaneously without causing data corruption.

Can you give me examples of thread-safe classes in the C++ standard library?

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

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

To ensure your classes are thread-safe, you can use synchronization mechanisms like mutexes or design your classes to be immutable.

What are the performance implications of using thread safety?

Using thread safety mechanisms can introduce overhead, potentially slowing down performance due to locking and context switching.
