Constructors and Destructors

explicit

auto_ptr (X* p = 0);

Constructs an object of class auto_ptr<X>, initializing the held pointer to p. Requires that

p points to an object of class X or a class derived from X for which delete p is defined

and accessible, or that p is a null pointer.

auto_ptr (const auto_ptr<X>& a);

Copy constructor. Constructs an object of class auto_ptr<X>, and copies the argument a

to *this. *this becomes the new owner of the underlying pointer.

~auto_ptr ();

Deletes the underlying pointer.

Operators

void

operator= (const auto_ptr<X>& a);

Assignment operator. Copies the argument a to *this. *this becomes the new owner of the

underlying pointer. If *this already owned a pointer, then that pointer is deleted first.

operator* () const;

Returns a reference to the object to which the underlying pointer points.
