    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let sftp = CkoSFtp()!

    // Pass a domain or IP address..
    var success: Bool = sftp.connect("my-sftp-server.com", port: 22)
    if success == true {
        success = sftp.authenticatePw("mySFtpLogin", password: "mySFtpPassword")
    }

    if success == true {
        success = sftp.initializeSftp()
    }

    if success != true {
        print("\(sftp.lastErrorText!)")
        return
    }

    // In this example, the we already have a symbolic link named "sshd_config"
    // in our SSH/SFTP user account's HOME directory.  Get the target of this link:
    var path: String? = sftp.readLink("sshd_config")
    if sftp.lastMethodSuccess != true {
        print("\(sftp.lastErrorText!)")
        return
    }

    print("symlink target path = \(path!)")

    // Output is:  
    // symlink target path = /etc/ssh/sshd_confi
