System.Threading (mscorlib.dll)

class

This class encapsulates the Win32 API OVERLAPPED structure. NativeOverlapped is needed to mimic the structure the API expects, but this class encapsulates the overlapped structure into a .NET class. You can create NativeOverlapped structures by calling Pack( ) , and create Overlapped objects with the static Unpack( ) method. To avoid a memory leak, each NativeOverlapped that you create must also be freed by calling the static Free( ) method. Unpack( ) does not free the memory.

 public class  Overlapped  {  // Public Constructors  public  Overlapped  ( );    public  Overlapped  (int   offsetLo   , int   offsetHi   , int   hEvent   , IAsyncResult   ar   );  // Public Instance Properties  public IAsyncResult  AsyncResult  {set; get; }    public int  EventHandle  {set; get; }    public int  OffsetHigh  {set; get; }    public int  OffsetLow  {set; get; }  // Public Static Methods  public static void  Free  (NativeOverlapped   *nativeOverlappedPtr   );    public static Overlapped  Unpack  (NativeOverlapped   *nativeOverlappedPtr   );  // Public Instance Methods  public NativeOverlapped*  Pack  (IOCompletionCallback   iocb   );    public NativeOverlapped*  UnsafePack  (IOCompletionCallback   iocb   ); }
