Atomically replaces the current value with
desired
. Memory is affected according to the value of
order
.
order
must be one of
std::memory_order_relaxed
,
std::memory_order_release
or
std::memory_order_seq_cst
. Otherwise the behavior is undefined.
Parameters
| desired | - |
the
weak_ptr
to store into the atomic variable
|
| order | - | memory order constraints to enforce |
Return value
(none)
Remarks
All changes to the
atomic_weak_ptr
object itself, and all associated
use_count
increments, are guaranteed to be performed atomically. Associated
use_count
decrements take place after the atomic operation, but are not required to be part of it. Any associated destruction or deallocation operations take place after the atomic operation and are not part of it.
