Pointers and references

Any pointer or reference to a native object is translated to a ptr<T> instance that wraps the pointer. This is the case for local variables, function parameters and return values: 
void ProgramClass::ProgramFunc(Window* window, Surface& surface)
{

// window is a ptr<Window>
    // surface is a ptr<Surface> too, hence why we use the -> operator
    window->SetSize(640, 480);
    surface->Create();

...
}
Pointers also support standard pointer arithmetic: 
void Function()
{
    int array[10] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };

log(array[0]); // 0
    ptr<int> p = array;
    p++;
    log(p[0]); // 1
    p += 2;
    log(p[1]); // 4

    ptr<int> p2 = p - 2;
    log(p2[0]); // 1

}
