## Declaration

```swift
func SCNetworkInterfaceSetMediaOptions(_ interface: SCNetworkInterface, _ subtype: CFString?, _ options: CFArray?) -> Bool
```

## Parameters

- `interface`: The network interface.
- `subtype`: The media subtype to set (for example, “autoselect” or “100baseTX”).
- `options`: The media options to set (for example, “half-duplex” or “full-duplex”). If NULL, the active options are not returned.

## Return Value
