Typical usage of autoptr

typedef auto_ptr<TypeName> TypeNamePtr;

TypeNamePtr func1() {

    TypeNamePtr p(new TypeName());

    return p;

}

 

void func2() {

    TypeNamePtr p = func1();

    p.DoSth();

}

And if without auto_ptr, func2 should delete p finally, but now we just ignore this step, it

will be automatically released.
