What is the difference between stdatomic and atomic in C++?

What is the difference between stdatomic and atomic in C++?

The main difference is that stdatomic provides a standardized way to perform atomic operations, while atomic is a more general term that can refer to any atomic type or operation.

Can you give me an example of how to use stdatomic?

Sure! Here's a simple example: you can use std::atomic<int> counter; to declare an atomic integer, and then use counter.fetch_add(1); to safely increment it.

Are there performance differences between using stdatomic and atomic?

Yes, stdatomic is designed to be more efficient and portable across different platforms, while atomic implementations may vary.

When should I use stdatomic over atomic?

You should use stdatomic when you need a portable and standardized way to handle atomic operations, especially in multi-threaded environments.
