Get the stringbuf object associated with the stream.
  Returns the stringbuf object associated with the stream.

Parameters.

none

 

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.

Example.

// 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;
}

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

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