auto_ptr::reset


public member function
void reset (X* p=0) throw();

Deallocate object pointed and set new value

Destructs the object pointed by the auto_ptr object, if any, and deallocates its memory (by calling operator delete). If a value for p is specified, the internal pointer is initialized to that value (otherwise it is set to the null pointer).

To only release the ownership of a pointer without destructing the object pointed by it, use member function release or auto_ptr::operator=|operator= instead.

Parameters

p
Pointer to element. Its value is set as the new internal pointer's value for the auto_ptr object.
X is auto_ptr's template parameter (i.e., the type pointed).

none

Return value

none

// auto_ptr::reset example
#include <iostream>
#include <memory>
using namespace std;

int main () {
  auto_ptr<int> p;

  p.reset (new int);
  *p=5;
  cout << *p << endl;

  p.reset (new int);
  *p=10;
  cout << *p << endl;

  return 0;
}


Output:
