# info

An arbitrary client-defined value (for instance, a pointer) to be associated with the stream and passed to the callback when it is invoked. If a non-NULL value is supplied for the retain callback the framework will use it to retain this value. If a non-NULL value is supplied for the release callback then when the stream is deallocated it will be used to release this value. This can be NULL.

## Declaration

```swift
var info: UnsafeMutableRawPointer?
```
