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.
