This structure has the same layout as the Win32 OVERLAPPED structure, with extra reserved data at the end, which is provided for backward compatibility. Create a NativeOverlapped instance by calling Overlapped.Pack( ). Each time an instance is created, it must be freed by calling the static method Overlapped.Free( ) to avoid a memory leak.

public struct NativeOverlapped {
// Public Instance Fields
   public int EventHandle;
   public int InternalHigh;
   public int InternalLow;
   public int OffsetHigh;
   public int OffsetLow;
}
