An abstract class which adds information to the OVERLAPPED structure to make it more useful.
class ACE_WIN32_Asynch_Result : public virtual ACE_Asynch_Result_Impl, public OVERLAPPED {
public:
friend class ACE_WIN32_Asynch_Accept;

const void *act (void) const;
int success (void) const;
const void *completion_key (void) const;

ACE_HANDLE event (void) const;
u_long offset (void) const;

protected:

These classes only works on Win32 platforms.
The implementation of ACE_Asynch_Transmit_File
and
ACE_Asynch_Accept
are only supported if ACE_HAS_WINSOCK2 is
defined or you are on WinNT 4.0 or higher.

u_long offset (void) const;
u_long offset_high (void) const;
