        !            14:     PURPOSE:    Server side of RPC distributed application xmit
        !            15:     
        !            16:     FUNCTIONS:  main() - registers server as RPC server
        !            17: 
        !            18:     COMMENTS:   This sample program generates a linked list to
        !            19:                 demonstrate how the list can be transmitted over
        !            20:                 the network more efficiently as a sized array.
        !            21:                 The pointers are rebuilt on the server side.
        !            22: 
        !            23:                 The [transmit_as] attribute (used in the typedef of
        !            24:                 DOUBLE_LINK_TYPE in the file XMIT.IDL) requires the
        !            25:                 four user-supplied functions whose names start with
        !            26:                 the name of the presented type, DOUBLE_LINK_TYPE.
        !            27: 
        !            28:                 The [in, out] attributes applied to remote procedure
        !            29:                 parameters require the two user-supplied functions
        !            30:                 midl_user_allocate and midl_user_free.
        !            31: 
        !            32:                 The other functions are utilities that are used to
        !            33:                 build or display the data structures.
