Return Value.
  A pointer to the stringbuf object associated with the stream.
  Notice that this pointer is never NULL, even if the buffer is not associated with any string object. It is a pointer to the private stringbuf object.

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

int main () {
  stringbuf *pbuf;
  ostringstream oss;

  pbuf=oss.rdbuf();
  pbuf->sputn ("Sample string",13);
  cout << pbuf->str();

  return 0;
}

Basic template member declaration ( basic_ostringstream<charT,traits,Allocator> ):

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