NAME

ACE_Asynch_Operation -

This is an interface base class for all asynch operations. The resposiblility of this class is to forward all methods to its delegation/implementation class, e.g., ACE_WIN32_Asynch_Operation or ACE_POSIX_Asynch_Operation.

SYNOPSIS

class ACE_Asynch_Operation { public: int open ( ACE_Handler &handler, ACE_HANDLE handle, const void *completion_key, ACE_Proactor *proactor ); int cancel (void); ACE_Proactor* proactor (void) const; virtual ~ACE_Asynch_Operation (void); protected: ACE_Asynch_Operation (void); ACE_Asynch_Operation_Impl *implementation (void) const; void implementation (ACE_Asynch_Operation_Impl *implementation); ACE_Proactor *get_proactor ( ACE_Proactor *user_proactor, ACE_Handler &handler ) const; ACE_Asynch_Operation_Impl *implementation_; };

DESCRIPTION

This works on Win32 (#if defined (ACE_WIN32) && !defined (ACE_HAS_WINCE)) platforms and on POSIX4 platforms with aio_* routines (#if defined (ACE_HAS_AIO_CALLS))

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.

Access methods.

ACE_Proactor* proactor (void) const;

virtual ~ACE_Asynch_Operation (void);
