How do I use std::atomic in C++11?

How do I use std::atomic in C++11?

You can use std::atomic to create atomic variables that are safe to use in multithreaded environments. For example, you can declare an atomic integer like this: std::atomic<int> atomicInt(0);.

What operations can I perform on std::atomic variables?

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

Are there any limitations to using std::atomic?

Yes, std::atomic only supports certain types, and operations are limited to those that can be performed atomically. Complex types may require additional synchronization.

Can I use std::atomic with custom types?

You can use std::atomic with custom types, but they must be trivially copyable and you need to provide a specialization for atomic operations.
