    FILE:       umarshp.c

    PURPOSE:    Remote procedures that are linked with the server
                side of RPC distributed application

    FUNCTIONS:  ModifyMyWString() - Display the string passed in, modify it, and return
				ModifyMyString() - 
                Shutdown() - shuts down the server side

    COMMENTS:   Related to umarshs.c

Function:   ModifyMyWString

Parameters: pStr : Pointer to pointer to UNICODE string

Returns:    none

Purpose:    Display the string passed in, modify it, and return

Comments:   This sample is meant to demonstrate a typical use of the
            represent_as attribute:  The client and server have different
            local views of the data, although the IDL file describes the
            wire contract.

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.
