NAME
      xdrsimple:   xdrbool, xdrchar, xdrdouble, xdrenum, xdrfloat,
      xdrfree, xdrint, xdrlong, xdrshort, xdruchar, xdrulong,
      xdrushort, xdrvoid - library routines for external data representation

DESCRIPTION
      XDR library routines allow C programmers to describe simple data
      structures in a machine-independent fashion.  Protocols such as remote
      procedure calls (RPC) use these routines to describe the format of the
      data.

      These routines require the creation of XDR streams [see xdrcreate(3N)].

   Routines
      See rpc(3N) for the definition of the XDR data structure.

      #include <rpc/xdr.h>

      boolt
      xdrbool(XDR *xdrs, boolt *bp);

            xdrbool translates between booleans (C integers) and their
            external representations.  When encoding data, this filter produces
            values of either 1 or 0.  This routine returns 1 if it succeeds, 0
            otherwise.

      boolt
      xdrchar(XDR *xdrs, char *cp);

            xdrchar translates between C characters and their external
            representations.  This routine returns 1 if it succeeds, 0
            otherwise.  Note:  encoded characters are not packed, and occupy 4
            bytes each.  For arrays of characters, it is worthwhile to consider
            xdrbytes, xdropaque or xdrstring [see xdrbytes, xdropaque and
            xdrstring in xdrcomplex(3N)].

      boolt
      xdrdouble(XDR *xdrs, double *dp);

            xdrdouble translates between C double precision numbers and their
            external representations.  This routine returns 1 if it succeeds, 0
            otherwise.

      boolt
      xdrenum(XDR *xdrs, enumt *ep);

            xdrenum translates between C enums (actually integers) and their
            external representations.  This routine returns 1 if it succeeds, 0
            otherwise.

      boolt
      xdrfloat(XDR *xdrs, float *fp);

            xdrfloat translates between C floats and their external
            representations.  This routine returns 1 if it succeeds, 0
            otherwise.

      void
      xdrfree(xdrproct proc, char *objp);

            Generic freeing routine.  The first argument is the XDR routine for
            the object being freed.  The second argument is a pointer to the
            object itself.  Note:  the pointer passed to this routine is not
            freed, but what it points to is freed (recursively).

      boolt
      xdrint(XDR *xdrs, int *ip);

            xdrint translates between C integers and their external
            representations.  This routine returns 1 if it succeeds, 0
            otherwise.

      boolt
      xdrlong(XDR *xdrs, long *lp);

            xdrlong translates between C long integers and their external
            representations.  This routine returns 1 if it succeeds, 0
            otherwise.

      boolt
      xdrshort(XDR *xdrs, short *sp);

            xdrshort translates between C short integers and their external
            representations.  This routine returns 1 if it succeeds, 0
            otherwise.

      boolt
      xdruchar(XDR *xdrs, char *ucp);

            xdruchar translates between unsigned C characters and their
            external representations.  This routine returns 1 if it succeeds, 0
            otherwise.

      boolt
      xdrulong(XDR *xdrs, unsigned long *ulp);

            xdrulong translates between C unsigned long integers and their
            external representations.  This routine returns 1 if it succeeds, 0
            otherwise.

      boolt
      xdrushort(XDR *xdrs, unsigned short *usp);

            xdrushort translates between C unsigned short integers and their
            external representations.  This routine returns 1 if it succeeds, 0
            otherwise.

      boolt
      xdrvoid(void);

            This routine always returns 1.  It may be passed to RPC routines
            that require a function parameter, where nothing is to be done.
