NAME

xdr_simple: xdr_bool, xdr_char, xdr_double, xdr_enum, xdr_float, xdr_free, xdr_int, xdr_long, xdr_short, xdr_u_char, xdr_u_long, xdr_u_short, xdr_void - 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 xdr_create(3N)].

Routines

See rpc(3N) for the definition of the XDR data structure.
#include <rpc/xdr.h>

bool_t
xdr_bool(XDR *xdrs, bool_t *bp);

     xdr_bool 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.
     bool_t
     xdr_char(XDR *xdrs, char *cp);

xdr_char 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 xdr_bytes, xdr_opaque or xdr_string [see xdr_bytes, xdr_opaque and xdr_string in xdr_complex(3N)].

bool_t
xdr_double(XDR *xdrs, double *dp);

xdr_double  translates  between  C   double   precision
numbers  and their external representations.  This rou-
tine returns 1 if it succeeds, 0 otherwise.
bool_t
xdr_enum(XDR *xdrs, enum_t *ep);

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

bool_t
xdr_float(XDR *xdrs, float *fp);

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

void
xdr_free(xdrproc_t proc, char *objp);

Generic freeing routine.  The first argument is the XDR
routine  for  the object being freed.  The second argu-
ment 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).
bool_t
xdr_int(XDR *xdrs, int *ip);

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

bool_t
xdr_long(XDR *xdrs, long *lp);

xdr_long translates between C long integers  and  their
external representations.  This routine returns 1 if it
succeeds, 0 otherwise.
bool_t
xdr_short(XDR *xdrs, short *sp);

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

bool_t
xdr_u_char(XDR *xdrs, char *ucp);

xdr_u_char translates between unsigned C characters and
their external representations.  This routine returns 1
if it succeeds, 0 otherwise.
bool_t
xdr_u_long(XDR *xdrs, unsigned long *ulp);

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

bool_t
xdr_u_short(XDR *xdrs, unsigned short *usp);

xdr_u_short  translates  between   C   unsigned   short
integers and their external representations.  This rou-
tine returns 1 if it succeeds, 0 otherwise.
bool_t
xdr_void(void);

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