< cpp | experimental | atomic weak ptr
| weak_ptr<T> load( std::memory_order order = std::memory_order_seq_cst ) const;
|
||
Atomically loads and returns the current value of the atomic_weak_ptr. Memory is affected according to the value of order.
order must be one of std::memory_order_relaxed, std::memory_order_consume, std::memory_order_acquire or std::memory_order_seq_cst. Otherwise the behavior is undefined.
