# createLink(to:named:in:context:replyHandler:)

Creates a new hard link.

```
func createLink(to item: FSItem, named name: FSFileName, in directory: FSItem, context: FSContext, replyHandler reply: @escaping @Sendable (FSCreateLinkResult?, (any Error)?) -> Void)
```

```
func createLink(to item: FSItem, named name: FSFileName, in directory: FSItem, context: FSContext) async throws -> FSCreateLinkResult
```

## 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.

`context`

An object that enables context-aware file system decisions throughout the operation.

`reply`

A block or closure to indicate success or failure. If creation succeeds, pass an instance of [`FSCreateLinkResult`](/documentation/FSKit/FSCreateLinkResult) containing the [`FSFileName`](/documentation/FSKit/FSFileName) of the newly-created link, the [`FSItem.Attributes`](/documentation/FSKit/FSItem/Attributes) of the linked item, the updated [`FSItem.Attributes`](/documentation/FSKit/FSItem/Attributes) of the parent directory, and the volume’s updated free space, along with a `nil` error. If creation fails, pass the relevant error as the second parameter; FSKit ignores the [`FSCreateLinkResult`](/documentation/FSKit/FSCreateLinkResult) instance in this case. For an `async` Swift implementation, there’s no reply handler; simply return the result instance or throw an error.

## Discussion

If creating the link fails, complete the request with an error with a domain of <doc://com.apple.documentation/documentation/Foundation/NSPOSIXErrorDomain> 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.
