# AUGraphNewNodeSubGraph(_:_:)

Creates a node object to represent a subgraph.

## Declaration

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

## Parameters

- `inGraph`: The AUGraph object that you want to add a subgraph to.
- `outNode`: The node that represents the subgraph.

## Return Value

Return Value A result code.

## Discussion

Discussion This function creates a node that represents a subgraph. The subgraph can be retrieved with the AUGraphGetNodeInfoSubGraph(_:_:_:) function. The subgraph is owned by the parent graph and will be disposed when the parent graph is disposed or when the node is removed from the parent graph.
