VMS Help TCPIP Services, Programming Interfaces, RPC XDR Routines, xdr_replymsg, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Describes ONC RPC reply messages. This routine is useful for
    users who want to generate messages without using the ONC RPC
    package. This routine interprets the message header and then
    calls either the xdr_accepted_reply or the xdr_rejected_reply
    routine to interpret the body of the RPC message.
