If volatile is useless for threading, why do atomic operations require pointers to volatile data?

Question

I\'ve been reading from many sources that the volatile keyword is not helpful in multithreaded scenarios. However, this assertion is constantly challenged by atomic operatio

Answer 1

C++11 has atomics for both volatile and non-volatile variables.

If the compiler intrinsics take a pointer to volatile int, that means you can use it even if the variable is volatile. It doesn't stop you from using the function on non-volatile data.
