# deactivateItem(_:replyHandler:)

Notifies the file system that the kernel is no longer making immediate use of the given item.

## Declaration

```swift
func deactivateItem(_ item: FSItem, replyHandler reply: @escaping @Sendable ((any Error)?) -> Void)
```

```swift
func deactivateItem(_ item: FSItem) async throws
```

## Parameters

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

## Discussion

Discussion This method gives a file system a chance to release resources associated with an item. However, this method prescribes no specific action; it’s acceptable to defer all reclamation until reclaimItem(_:replyHandler:). This method is the equivalent of VFS’s VNOP_INACTIVE. FSKit restricts calls to this method based on the current value of itemDeactivationPolicy.
