# copyDescription

Callback used to create a descriptive string representation of the data pointed to by info. In implementing this function, return a reference to a CFString object that describes your allocator and some characteristics of your user-defined data, which is used by CFCopyDescription(). You can set this field to NULL, in which case Core Foundation will provide a rudimentary description.

## Declaration

```swift
var copyDescription: CFAllocatorCopyDescriptionCallBack?
```
