obj as if by obj->load()
obj as if by obj->load(order)
| obj | - | pointer to the atomic object to modify |
| order | - | the memory synchronization ordering for this operation: only std::memory_order_relaxed, std::memory_order_consume, std::memory_order_acquire and std::memory_order_seq_cst are permitted. |
The value that is held by the atomic object pointed to by obj.
| atomically obtains the value of the atomic object (public member function of std::atomic<T>) |
|
|
(C++11)(C++11) | atomically replaces the value of the atomic object with a non-atomic argument (function template) |
|
(C++11) | defines memory ordering constraints for the given atomic operation (enum) |
| specializes atomic operations for std::shared_ptr (function template) |
