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

    Used for encoding reply messages. This routine encodes the status
    of the RPC call and, in the case of success, the call results
    as well. This routine is useful for users who wish to generate
    messages without using the ONC RPC package. It returns the
    message-accepted variant of a reply message union in the arp
    argument.

    The xdr_replymsg routine calls this routine.
