Serializes and deserializes unsigned VAX quadwords (known in XDR
    as hyperintegers).
    Format
      #include  <tcpip$rpcxdr.h>
      bool_t  xdr_u_hyper(XDR *xdrs, unsigned quad *uhp);

1  –  Arguments

 xdrs
    A pointer to an XDR stream handle created by one of the XDR
    stream-handle creation routines.
 uhp
    A pointer to the unsigned hyperinteger.

2  –  Description

    A filter primitive that translates between unsigned hyperintegers
    and their external representations.

3  –  Return Values

    TRUE               Indicates success.
