NAME¶

std::experimental::atomic_weak_ptr::load - std::experimental::atomic_weak_ptr::load

Synopsis¶

weak_ptr<T> load( std::memory_order order = std::memory_order_seq_cst ) const
noexcept;

Atomically loads and returns the current value of the atomic_weak_ptr. 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

Remarks

All associated use_count increments are guaranteed to be performed as part of the
atomic operation.

Return value¶

The current value of the atomic_weak_ptr.
