xdr_create: xdr_destroy, xdrmem_create, xdrstdio_create-library routines for external data representation stream creation
XDR library routines allow C programmers to describe arbitrary data structures in a machine-independent fashion. Protocols such as communications calls use these routines to describe the format of the data.
These routines deal with the creation of XDR streams. XDR streams have to be created before any data can be translated into XDR format.
#include <rpc/xdr.h>
void xdr_destroy(XDR *xdrs)
XDR stream, xdrs. Destruction usually involves freeing private data structures associated with the stream. Using xdrs after invoking xdr_destroy is undefined.
void xdrmem_create(XDR *xdrs, const caddr_t addr, const u_int size,
const enum xdr_op op)
XDR stream object pointed to by xdrs. The stream's data is written to, or read from, a chunk of memory at location addr whose length is no more than size bytes long. The op determines the direction of the XDR stream (either XDR_ENCODE, XDR_DECODE, or XDR_FREE).
void xdrstdio_create(XDR *xdrs, FILE *file, const enum xdr_op op)
XDR stream object pointed to by xdrs. The XDR stream data is written to, or read from, the standard I/O stream file. The parameter op determines the direction of the XDR stream (either XDR_ENCODE, XDR_DECODE, or XDR_FREE). Warning: the destroy routine associated with such XDR streams calls fflush on the file stream, but never fclose [see fclose(3S)].
