# CFFileSecurityClearProperties(_:_:)

Clears properties from a CFFileSecurityRef object.

## Declaration

```swift
func CFFileSecurityClearProperties(_ fileSec: CFFileSecurity!, _ clearPropertyMask: CFFileSecurityClearOptions) -> Bool
```

## Parameters

- `fileSec`: The file security properties to clear.
- `clearPropertyMask`: The file security properties to clear.

## Return Value

Return Value Returns true if the file security properties were successfully cleared, or false otherwise.

## Discussion

Discussion One common use for CFFileSecurityRef objects is to clone the permissions from one file to another. In this use, you may want to copy only a subset of the permissions. This function lets you delete the specific permissions that you do not want to change prior to applying the set of permissions to a different file.
