On the other hand does nonatomic incorporate nothing for your code. So it's only thread Protected in the event you code stability system your self.
I know that std::atomic is surely an atomic item. But atomic to what extent? To my knowing an operation may be atomic. What precisely is meant by generating an item atomic? By way of example if there are two threads concurrently executing the next code:
But I suppose It truly is achievable for that function to return precisely the same worth 2 times, appropriate? As an example, thread A phone calls the purpose, increments the value, but then halts though thread B is available in and likewise increments the value, lastly A and B both return exactly the same price.
as should they do - they probably truly use The shop buffer, However they flush it as well as instruction pipeline prior to the load and await it to empty right after, and possess a lock around the cacheline that they just take as part o the load, and release as Component of the store - all to be sure that the cacheline does not disappear between and that no-one else can see The shop buffer contents while this is going on.
So Except if you now recognize that and why you would like atomic operations, the type is probably not of Substantially use for yourself.
