Sets the number name for the given element of the video object.

## Declaration

kern_return_t SetElementNumberName(IOUserVideoObjectPropertyElement in_element, IOUserVideoObjectPropertyScope in_scope, OSString *in_number_name);
```

## Parameters

- `in_element`: The IOUserVideoObjectPropertyElement
- `in_scope`: The IOUserVideoObjectPropertyScope

## Discussion

Discussion If the object can change the name dynamically, the object sends a notification to the host to update the object state on success. The object’s work queue synchronizes access to the value.
