// auto_ptr::operator-> example
#include <iostream>

using namespace std;

int main () {
  typedef pair<int*,ptrdiff_t> mypair;

  auto_ptr<mypair> p (new mypair);

  *p = get_temporary_buffer<int>(5);

  if (p->second >= 5) {
    for (int i=0; i<5; i++)
      p->first[i]=i*5;

    for (int i=0; i<5; i++)
      cout << p->first[i] << " ";
