## Declaration

```swift
func outputConnectionPoints(for node: AVAudioNode, outputBus bus: AVAudioNodeBus) -> [AVAudioConnectionPoint]
```

## Parameters

- `node`: The node with the output connections you’re querying.
- `bus`: The node’s output bus for connections you’re querying.

## Return Value

Return Value An array of AVAudioConnectionPoint objects with connection information on the node’s output bus.

## Discussion
