An IntPtr is a pointer to a memory location (unmanaged) that adapts to the platform it is running on (64-bit, etc.) UNLIKE a standard int/Integer. You should always use this type for unmanaged calls that require it, even though an int will appear to work on your development machine.

A HandleRef is essentially an IntPtr to a handle and a reference to the object the handle belongs to. Using HandleRef prevents the GC from collecting the object until the native method is done with it.
