What are the best practices for using stdatomic in C++?

When using stdatomic in C++, it's important to understand memory orderings, use atomic types appropriately, and avoid data races.

Can you explain the different memory orderings available?

Sure! The main memory orderings are relaxed, acquire, release, and sequentially consistent. Each affects visibility and ordering of operations.

How do I choose the right memory ordering for my use case?

Choose relaxed for performance when ordering isn't critical, acquire/release for synchronization, and sequentially consistent for strict ordering.

Are there any common pitfalls to avoid?

Yes, common pitfalls include using atomic operations without understanding their implications, and mixing atomic and non-atomic accesses.
