Function documentation
template<class T>
sead::
Directly initialises the underlying atomic with the specified value. Note that initialisation is not atomic.
template<class T>
T sead::
| Returns | the previous value |
|---|
Exchange/swap the current value, as if with memory_order_relaxed.
template<class T>
bool sead::
| Parameters | |
|---|---|
| expected | The value expected to be found in the atomic object, and to be replaced. |
| desired | The new value to store in the atomic object if expected was found. |
| original | The value that was found in the atomic object if the comparison fails. May be null. Note that this is only updated when false is returned. |
| Returns | true if and only if the value was modified |
Load the current value and if it is equal to expected, store desired as if with memory_order_relaxed. Otherwise, this sets original to the current value.
