1) Atomically obtains the value pointed to by
obj as if by obj->load() 2) Atomically obtains the value pointed to by
obj as if by obj->load(order) Parameters
| 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. |
Return value
The value that is held by the atomic object pointed to by obj.
