void * GetReference();
```

Creating a Driver Using the DriverKit SDK

## Return Value

Return Value A pointer to the additional storage you requested at creation time. This method returns NULL if you passed 0 to the referenceSize parameter of the Create method. It also returns NULL if the action object doesn’t belong to the current process.
