NAME

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

The volatile-qualified version is deprecated if (since C++20)
std::atomic<T>::is_always_lock_free is false.

Parameters

order - memory order constraints to enforce

Return value

The current value of the atomic variable.
