1,2) Atomically obtains the value pointed to by obj as if by obj->load().
3,4) Atomically obtains the value pointed to by obj as if by obj->load(order).
If order is one of std::memory_order_release and std::memory_order_acq_rel, the behavior is undefined.

Parameters

obj - pointer to the atomic object to modify
order - the memory synchronization ordering for this operation

Return value

The value that is held by the atomic object pointed to by obj.
