std::atomic<T>::load: std::atomic<T>::load

NAME

std::atomic<T>::load - std::atomic<T>::load

Synopsis

T load( std::memory_order order = std::memory_order_seq_cst ) const noexcept; (since C++11)
T load( std::memory_order order = 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.
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 atomic variable.
