# CFTreeGetChildren(_:_:)

Fills a buffer with children from the tree.

## Declaration

```swift
func CFTreeGetChildren(_ tree: CFTree!, _ children: UnsafeMutablePointer<Unmanaged<CFTree>?>!)
```

## Parameters

- `tree`: The tree to examine.
- `children`: The C array of pointer-sized values to be filled with the children from tree. This value must be a valid pointer to a C array of at least the size of the number of children in tree.

You are responsible for retaining and releasing the returned objects as needed.
