# CFBagContainsValue(_:_:)

Reports whether or not a value is in a bag.

## Declaration

```swift
func CFBagContainsValue(_ theBag: CFBag!, _ value: UnsafeRawPointer!) -> Bool
```

## Parameters

- `theBag`: The bag to examine.
- `value`: The value to match in theBag. The equal callback provided when theBag 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 theBag, is not understood by the equal callback, the behavior is undefined.

## Return Value

Return Value true if value is contained in theBag, otherwise false.
