    NAME:       ServiceEntry

    SYNOPSIS:   This is the "real" entrypoint for the service.  When
                the Service Controller dispatcher is requested to
                start a service, it creates a thread that will begin
                executing this routine.

    ENTRY:      cArgs - Number of command line arguments to this service.

                pArgs - Pointers to the command line arguments.

                pGlobalData - Points to global data shared amongst all
                    services that live in TCPSVCS.EXE.

    EXIT:       Does not return until service is stopped.

    HISTORY:
