# AUGraphGetNodeInteractions(_:_:_:_:)

Retrieves information about the interactions in an audio processing graph for a given node.

## Declaration

```swift
func AUGraphGetNodeInteractions(_ inGraph: AUGraph, _ inNode: AUNode, _ ioNumInteractions: UnsafeMutablePointer<UInt32>, _ outInteractions: UnsafeMutablePointer<AUNodeInteraction>) -> OSStatus
```

## Parameters

- `inGraph`:
- `inNode`:
- `ioNumInteractions`: On input, specifies the number of interactions that can be returned. On output, the number of interactions returned.
- `outInteractions`: The interactions that the specified node is involved in.

## Return Value

Return Value A result code.
