std::atomic::load(3) C++ Standard Libary std::atomic::load(3)

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.
