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
XDR library routines allow C programmers to describe simple data structures in a machine-independent fashion. Protocols such as communications calls use these routines to describe the format of the data.
These routines require the creation of XDR streams [see xdr_create(3I)].
#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(3I)].
bool_t xdr_double(XDR *xdrs, double *dp)
xdr_double translates between C double precision numbers and their external representations. This routine 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)
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).
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 routine returns 1 if it succeeds, 0 otherwise.
bool_t xdr_void(void)
1. It may be passed to RPC routines that require a function parameter, where nothing is to be done.
