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
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.
