T load( memory_order = std::memory_order_seq_cst ) const;
T load( memory_order = std::memory_order_seq_cst ) const volatile;

Atomically loads and returns the current value of the atomic variable. Memory is affected according to the value of memory_order.

memory_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.
