Tools.h++ Class Reference

An XDR stream must first be created by calling the appropriate creation routine. XDR streams
currently exist for encoding/decoding of data to or from standard iostreams and file streams,
TCP/IP connections and Unix files, and memory. These creation routines take arguments that
are tailored to the specific properties of the stream. After the XDR stream has been created, it
can then be used as an argument to the constructor for a RWXDRostream object.
RWXDRostream can be interrogated as to the status of the stream using member functions
bad(), clear(), eof(), fail(), good(), and rdstate().

Example
The example that follows is a "writer" program that encodes an XDR structure onto a file
stream. The example for class RWXDRistream is the "reader" program that decodes the XDR
structures into a machine representation for a data type. The library that supports XDR routines
must be linked in. The name of this library is not standard.
#include <rw/xdrstrea.h>
#include <rw/rstream.h>
#include <stdio.h>
main(){
XDR xdr;
FILE* fp = fopen("test","w+");
xdrstdio_create(&xdr, fp, XDR_ENCODE);
RWXDRostream rw_xdr(&xdr);
for(int i=0; i<10; ++i)
rw_xdr << i; // encode integer data
fclose(fp);
}
Public Constructor
RWXDRostream(XDR* xp);
Initialize a RWXDRostream from the XDR structure xp.
RWXDRostream(streambuf*);
Initialize RWXDRostream with a pointer to streambuf. streambuf must already be
allocated.
RWXDRostream(ostream&);
