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
.
