# CFBinaryHeapApplyFunction(_:_:_:)

Iteratively applies a function to all the values in a binary heap.

## Declaration

```swift
func CFBinaryHeapApplyFunction(_ heap: CFBinaryHeap!, _ applier: ((UnsafeRawPointer?, UnsafeMutableRawPointer?) -> Void)!, _ context: UnsafeMutableRawPointer!)
```

## Parameters

- `heap`: The binary heap to use.
- `applier`: The callback function to call once for each value in heap.
- `context`: A program-defined value that is passed to the applier callback function, but is otherwise unused by this function.
