Routine Description:
    This routine calls a common bind routine that is shared by all services.
    This routine is called from the server service client stubs when
    it is necessary to bind to a server.

Arguments:

    ServerName - A pointer to a string containing the name of the server
        to bind with.

Return Value:

    The binding handle is returned to the stub routine.  If the
    binding is unsuccessful, a NULL will be returned.

Routine Description:

    This routine calls a common unbind routine that is shared by

    This routine is called from the server service client stubs when

Arguments:

    ServerName - This is the name of the server from which to unbind.

    BindingHandle - This is the binding handle that is to be closed.

Return Value:

    none.
