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

Atomically loads and returns the current value of the atomic_shared_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_shared_ptr.
