# CGDataConsumerReleaseInfoCallback

Releases any private data or resources associated with the data consumer.

## Declaration

```swift
typealias CGDataConsumerReleaseInfoCallback = (UnsafeMutableRawPointer?) -> Void
```

## Parameters

- `info`: A generic pointer to private data shared among your callback functions. This is the same pointer you supplied to doc://com.apple.coregraphics/documentation/CoreGraphics/CGDataConsumer/init(info:cbks:).

## Discussion

Discussion When Core Graphics frees a data consumer that has an associated release function, the release function is called. For information on how to associate your callback function with a data consumer, see init(info:cbks:) and CGDataConsumerCallbacks.
