# AUGraphGetIndNode(_:_:_:)

Gets the audio processing graph node at a given index.

## Declaration

```swift
func AUGraphGetIndNode(_ inGraph: AUGraph, _ inIndex: UInt32, _ outNode: UnsafeMutablePointer<AUNode>) -> OSStatus
```

## Parameters

- `inGraph`: The AUGraph object to get the node from.
- `inIndex`: The index of the node to get.
- `outNode`: On output, the node at the specified index.

## Return Value

Return Value A result code.

## Discussion

Discussion By using AUGraphGetNodeCount in conjunction with this call, you can iterate through the nodes of an audio processing graph.
