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

    Serializes and deserializes indirect pointers and the data being
    pointed to.
    Format
      #include  <tcpip$rpcxdr.h>
      bool_t  xdr_reference(XDR *xdrs, char **objpp, u_int objsize,
              xdrproc_t objproc);

1 - Arguments

 xdrs
    A pointer to an XDR stream handle created by one of the XDR
    stream handle creation routines.
 objpp
    A pointer to a pointer to the structure containing the data being
    converted. If objpp is zero, the xdr_reference routine allocates
    the necessary storage when decoding. This argument must be non-
    zero during encoding.
 objsize
    The size of the structure in bytes.
 objproc
    The XDR procedure that filters the structure between its local
    form and its external representation.

2 - Description

    A primitive that provides pointer chasing within structures.

3 - Return Values

    TRUE               Indicates success.
    FALSE              Indicates failure.
