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.
