    A CirioNubProc Foo is declared like

        CirioNubRetCode Foo(int argc, unsigned *args);

    See the type declaration in CirioNubInstall.h.
    Foo is invoked as a result of a message from the other side.
    The calling procedure and Foo must agree on the number and types
        of arguments.
    Foo returns results by calling the marshalling procedures (below)
        and returning the appropriate CirioNubRetCode value.
