# unmount(replyHandler:)

Unmounts this volume.

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

```
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.
