# getParentIterator

Returns an iterator over an registry entry's parent entries in a specified plane.

## Declaration

```occ
virtual OSIterator * getParentIterator(
 const IORegistryPlane *plane ) const; 
```

## Parameters

- `plane`: The plane object.

## Return Value

Return Value Returns an iterator over the parents of the registry entry, or zero if there is a resource failure. The iterator must be released when the iteration is finished. All objects returned by the iteration are retained while the iterator is valid, though they may no longer be attached during the iteration.
