# CFBinaryHeapGetMinimumIfPresent(_:_:)

Returns the minimum value in a binary heap, if present.

## Declaration

```swift
func CFBinaryHeapGetMinimumIfPresent(_ heap: CFBinaryHeap!, _ value: UnsafeMutablePointer<UnsafeRawPointer?>!) -> Bool
```

## Parameters

- `heap`: The binary heap to use.
- `value`: On return, the minimum value in heap as determined by the binary heap’s compare callback. If heap contains several equal minimum values, any one may be returned. If the value is a Core Foundation object, ownership follows the https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-SW1.

## Return Value

Return Value true if a minimum value exists in heap, false otherwise. false is returned only if heap is empty.
