What are some examples of stdatomic usage in C++?

Can you give me some examples of how to use stdatomic in C++?

Sure! The stdatomic library provides atomic operations for variables. For example, you can use std::atomic<int> to create an atomic integer.

How do I perform atomic operations like incrementing a value?

You can use the fetch_add method. For instance: atomicInt.fetch_add(1); will safely increment the value.

What about using std::atomic with pointers?

You can use std::atomic<T*> for pointers. For example, std::atomic<int*> atomicPtr; allows you to perform atomic operations on pointers.

Are there any performance considerations I should be aware of?

Yes, atomic operations can be slower than non-atomic ones due to memory ordering and synchronization, so use them judiciously.
