createLink(to:named:inDirectory:replyHandler:)

Creates a new hard link.

Declaration

func createLink(to item: FSItem, named name: FSFileName, inDirectory directory: FSItem, replyHandler reply: @escaping  @Sendable (FSFileName?, (any Error)?) -> Void)
func createLink(to item: FSItem, named name: FSFileName, inDirectory directory: FSItem) async throws -> FSFileName

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 of the newly-created link and a nil error. If creation fails, pass the relevant error as the second parameter; FSKit ignores any Fsfilename in this case. For an async Swift implementation, there’s no reply handler; simply return the Fsfilename or throw an error.

Discussion

If creating the link fails, complete the request with an error with a domain of 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.
