    When STDIN or STDOUT is specified, data is transmitted via the
    connection between the client and the server.

I think the names STDIN and STDOUT are causing the confusion: they're
just the server's names for the client/server connection and don't
have anything to do with the client's stdin and stdout.  The client
writes data to and reads data from the connection using the API
functions for doing so; where the client gets or puts that data is
up to the application.
