How do I use std::atomic in C++?

How do I use std::atomic in C++?

You can use std::atomic to perform atomic operations on variables, ensuring thread safety. For example, you can declare an atomic integer like this: std::atomic<int> counter(0);.

What operations can I perform with std::atomic?

You can perform operations like load, store, exchange, and fetch_add. For instance, counter.fetch_add(1); increments the counter atomically.

Are there any limitations to using std::atomic?

Yes, std::atomic can only be used with certain types, and complex types may require additional considerations for atomicity.

Can I use std::atomic with custom data types?

You can, but your custom type must meet specific requirements, such as being trivially copyable and having a defined atomic operation.

Where can I find more examples of std::atomic usage?

You can find more examples in the C++ standard library documentation or various programming tutorials online.
