# CFDictionaryContainsValue(_:_:)

Returns a Boolean value that indicates whether a given value is in a dictionary.

## Declaration

```swift
func CFDictionaryContainsValue(_ theDict: CFDictionary!, _ value: UnsafeRawPointer!) -> Bool
```

## Parameters

- `theDict`: The dictionary to examine.
- `value`: The value for which to find matches in theDict. The value equal callback provided when the dictionary was created is used to compare. If the equal callback was NULL, pointer equality (in C, ==) is used. If value, or any other value in the dictionary, is not understood by the equal callback, the behavior is undefined.

## Return Value

Return Value true if value is in the dictionary, otherwise false.
