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
.
Exceptions
noexcept
