# createLink(to:named:inDirectory:replyHandler:) Creates a new hard link. ``` func createLink(to item: FSItem, named name: FSFileName, inDirectory directory: FSItem, replyHandler reply: @escaping @Sendable (FSFileName?, (any Error)?) -> Void) ``` ## Parameters `item` The existing item to which to link. `name` The name for the new link. `directory` The directory in which to create the link. `reply` A block or closure to indicate success or failure. If creation succeeds, pass an [`FSFileName`](/documentation/FSKit/FSFileName) of the newly-created link and a `nil` error. If creation fails, pass the relevant error as the second parameter; FSKit ignores any [`FSFileName`](/documentation/FSKit/FSFileName) in this case. For an `async` Swift implementation, there’s no reply handler; simply return the [`FSFileName`](/documentation/FSKit/FSFileName) or throw an error. ## Discussion If creating the link fails, complete the request with an error with a domain of and the following error codes: - `EEXIST` if there’s already an item named `name` in the directory. - `EMLINK` if creating the link would exceed the maximum number of hard links supported on `item`. - `ENOTSUP` if the file system doesn’t support creating hard links to the type of file system object that `item` represents. --- Copyright © 2026 Apple Inc.
