stub
     
        1.  A dummy procedure used when linking a program
        with a {run-time library}.  The stub routine need not contain
        any code and is only present to prevent "undefined label"
        errors at link time.
     
        2.  A local procedure in a {remote
        procedure call}.  The {client} calls the stub to perform some
        task and need not necessarily be aware that RPC is involved.
        The stub transmits parameters over the network to the {server}
        and returns the results to the caller.
