obj with the value of desr as if by obj->store(desr)
obj with the value of desr as if by obj->store(desr, order)
| 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. |
none.
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 |
| atomically replaces the value of the atomic object with a non-atomic argument (public member function of std::atomic) |
|
|
(C++11)(C++11) | atomically obtains the value stored in an atomic object (function template) |
|
(C++11) | defines memory ordering constraints for the given atomic operation (enum) |
specializes atomic operations for std::shared_ptr (function template) |
