    PURPOSE:    Utility functions used by both client and server 
                sides of the RPC distributed application. 
                This sample demonstrates the transmit_as example. 
                A doubly-linked list is transmitted over the network 
                as a sized array. 
 
    RELATED:    repass.c - server main 
                repasp.c - remote procedures 
                repasc.c - client main 
 
    FUNCTIONS:  WCHAR_STRING_to_local    - convert WCHAR_STRING to CHAR_STRING 
                WCHAR_STRING_from_local  - convert CHAR_STRING to WCHAR_STRING 
                WCHAR_STRING_free_inst   - free CHAR_STRING memory 
                WCHAR_STRING_free_local  - free WCHAR_STRING memory 
                midl_user_allocate - user-supplied memory allocator 
                midl_user_free - user-supplied routine to free memory 
 
 
    COMMENTS:   This sample program generates a client and server can share 
                an interface, but one side can use a different representation 
                than the other. 
 
                The client side in this example does all operations using 
                character strings, and the server side does all operations 
                using UNICODE strings.  Two procedures are provided, one 
                defined with ASCII strings, one with UNICODE strings. 
                The wire format reflects these definitions, yet the client 
                and server see pure ASCII and pure UNICODE respectively. 
 
                The [represent_as] attribute (used in the client and server 
                side acf files) requires the four user-supplied functions 
                whose names start with the name of the transmitted type 
                (in the client side's case: WCHAR_STRING) 
 
                The [in, out] attributes applied to remote procedure 
                parameters require the two user-supplied functions 
                midl_user_allocate and midl_user_free. 
 
                The other functions are utilities that are used to 
                build or display the data structures.
