std::atomic_ref
 
T load( std::memory_order order = std::memory_order_seq_cst ) const noexcept;
 (since C++20)

Atomically loads and returns the current value of the referenced object. 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.

Parameters

order - memory order constraints to enforce

Return value

The current value of the referenced object.
