NAME¶

std::atomic::load - std::atomic::load

Synopsis¶

T load( std::memory_order order (1) (since C++11)
= std::memory_order_seq_cst ) const noexcept;
T load( std::memory_order order (2) (since C++11)
= std::memory_order_seq_cst ) const volatile noexcept;

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

If order is one of std::memory_order_release and std::memory_order_acq_rel, the
behavior is undefined.

It is deprecated if std::atomic<T>::is_always_lock_free is false and (since C++20)
overload (2) participates in overload resolution.

Parameters¶

order - memory order constraints to enforce

Return value¶

The current value of the atomic variable.
