```

## Parameters

- `in_driver`: The doc://com.apple.audiodriverkit/documentation/AudioDriverKit/IOUserAudioDriver that owns this object.
- `in_is_acquirable`: A Boolean value that specifies if the box supports being acquired.
- `in_box_uid`: The name of the box, as an doc://com.apple.documentation/documentation/DriverKit/OSString.

## Return Value
