C++ Pointer (Pass By Reference) Question

Question

A pointer that is passed-in-by-reference. Why? aren't pointers just references anyways? What's really happening to this parameter?

void someFunc(MyPtr*& Object)
{

}

Answer 1

Simply speaking, it gives you the ability to change the pointer itself: it can be changed to point to another location in the function. And the change will be reflected outside.
