VMS Help RPCGEN, Qualifiers, /XDR_FILE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Optional.
    DIGITAL UNIX equivalent: -c
    Default: Create an XDR file.

    You can customize some of your XDR routines by leaving those data
    types undefined. For every data type that is undefined, RPCGEN
    assumes that there exists a routine with the name xdr_  prepended
    to the name of the undefined type.

    Mutually exclusive with the /CLIENT_STUBS_FILE, /DISPATCH_TABLE,
    /HEADER_FILE, /TRANSPORT, and /SERVER_STUBS_FILE qualifiers.
