    PURPOSE:    Remote procedures that are linked with the server 
                side of RPC distributed application 
 
    FUNCTIONS:  ModifyListProc() - changes the doubly-linked list 
                Shutdown() - shuts down the server side

Function:   ModifyListProc 
 
Parameters: pFirst : Pointer to the head of a doubly-linked list. 
 
Returns:    none 
 
Purpose:    Display the list passed to the function. 
            For each element in the list, add another element. 
            Display the modified list. 
 
Comments:   This sample is meant to demonstrate a typical use of the 
            transmit_as attribute:  A complex data structure is simplified 
            for transmission over the network, restored on the server, 
            then manipulated by the remote function on the server. 
            The modified data is returned to the client. 
 
            Calls InsertNewNode(param1, param2), a utility routine 
            in xmits.c that creates a new node, assigns to it the 
            value param1, and inserts it into the list after param2.

Function:   Shutdown 
 
Parameters: none 
 
Returns:    none 
 
Purpose:    Make the server stop listening for client applications. 
 
Comments:   The two NULL parameters passed to RpcServerUnregisterIf are 
            a show of brute force:  they tell the function to turn 
            off all registered interfaces.  See the RPC API function 
            reference for more information about these functions.
