# unmount(replyHandler:)

Unmounts this volume.

## Declaration

```swift
func unmount(replyHandler reply: @escaping @Sendable () -> Void)
```

```swift
func unmount() async
```

## Parameters

- `reply`: A block or closure to indicate success or failure. If unmounting fails, pass an error as the one parameter to the reply handler. If unmounting succeeds, pass nil. For an async Swift implementation, there’s no reply handler; simply return normally.
