1) Atomically replaces the value pointed to by
obj
with the value of desr
as if by obj->store(desr)2) Atomically replaces the value pointed to by
obj
with the value of desr
as if by obj->store(desr, order)Parameters
obj | - | pointer to the atomic object to modify |
desr | - | the value to store in the atomic object |
order | - | the memory synchronization ordering for this operation: only std::memory_order_relaxed, std::memory_order_release and std::memory_order_seq_cst are permitted. |
Return value
none.
Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
DR | Applied to | Behavior as published | Correct behavior |
---|---|---|---|
P0558R1 | C++11 | exact type match required because T is deduced from multiple arguments
|
T is deduced from the atomic argument only
