Get a Remote File's Group

See more SFTP Examples

Demonstrates the Chilkat SFtp.GetFileGroup method, which returns a remote file's group ownership. The arguments are the remote path (or handle), whether symbolic links are followed, and whether the first argument is a handle.

    var success: Bool = false

    //  Demonstrates the SFtp.GetFileGroup method, which returns a remote file's group ownership.  The
    //  1st argument is the remote path (or handle), the 2nd selects whether symbolic links are
    //  followed, and the 3rd indicates whether the 1st argument is a handle.

    //  from an interactive prompt, environment variable, or a secrets vault.
