func AEPutAttributePtr(_ theAppleEvent: UnsafeMutablePointer<AppleEvent>!, _ theAEKeyword: AEKeyword, _ typeCode: DescType, _ dataPtr: UnsafeRawPointer!, _ dataSize: Size) -> OSErr
```

## Parameters

- `theAppleEvent`: A pointer to the Apple event to add an attribute to. See the doc://com.apple.documentation/documentation/coreservices/appleevent data type.
