# CFAttributedStringGetAttributeAndLongestEffectiveRange(_:_:_:_:_:)

Returns the value of a given attribute of an attributed string at a specified location.

## Declaration

```swift
func CFAttributedStringGetAttributeAndLongestEffectiveRange(_ aStr: CFAttributedString!, _ loc: CFIndex, _ attrName: CFString!, _ inRange: CFRange, _ longestEffectiveRange: UnsafeMutablePointer<CFRange>!) -> CFTypeRef!
```

## Parameters

- `aStr`: The attributed string to examine.
- `loc`: The location in str at which to determine the attributes. It is a programming error for loc to specify a location outside the bounds of str.
- `attrName`: The name of the attribute whose value you want to determine.
- `inRange`: The range in str within which you want to find the longest effective range of the attributes at loc. inRange must not exceed the bounds of str.
- `longestEffectiveRange`: If not NULL, upon return contains the maximal range within inRange over which the exact same set of attributes apply. The returned range is clipped to inRange.

## Return Value

Return Value A dictionary that contains the attributes of str at the specified location. Ownership follows the The Get Rule.
