# CFBagGetValue(_:_:)

Returns a requested value from a bag.

```
func CFBagGetValue(_ theBag: CFBag!, _ value: UnsafeRawPointer!) -> UnsafeRawPointer!
```

## Parameters

`theBag`

The bag to examine.

`value`

The value for which to find matches 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

A pointer to `value`, or `NULL` if `value` is not in `theBag`. If the value is a Core Foundation object, ownership follows the [The Get Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-SW1).

## Discussion

Depending on the implementation of the equal callback specified when creating `theBag`, the value returned may not have the same pointer equality as `value`.
