public member function
stringbuf* rdbuf ( ) const;

Get/set the associated stringbuf object

Returns a pointer to the stringbuf object associated with the stream.

Parameters

none

// istringstream::rdbuf
#include <iostream>
#include <sstream>
#include <string>
using namespace std;

int main () {
  stringbuf *pbuf;
  istringstream iss;
  string mystr ("This is a sample string");

  iss.str (mystr);

  pbuf=iss.rdbuf();

  int size = pbuf->in_avail();

  for (int n=0; n<size; n++)
    cout << (char) pbuf->sbumpc();

  return 0;
}


This is an elaborate way to print out a string by using the string stream buffer members.

Basic template member declaration

( basic_istringstream<charT,traits,Allocator> )
  
basic_stringbuf<charT,traits,Allocator> * rdbuf () const;
