Member Function Documentation

virtual const void* ACE_Asynch_Result_Impl::act (  void    )  const [pure virtual]

ACT associated with the operation. Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::act.

virtual size_t ACE_Asynch_Result_Impl::bytes_transferred (  void    )  const [pure virtual]

Number of bytes transferred by the operation. Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::bytes_transferred.

virtual void ACE_Asynch_Result_Impl::complete (  size_t    bytes_transferred, int    success, const void *    completion_key, u_long    error = 0 )  [pure virtual]

This is called when the asynchronous operation completes. Implemented in ACE_POSIX_Asynch_Read_Stream_Result. Referenced by ACE_WIN32_Proactor::application_specific_code, and ACE_POSIX_Proactor::application_specific_code.

virtual const void* ACE_Asynch_Result_Impl::completion_key (  void    )  const [pure virtual]

This ACT is not the same as the ACT associated with the asynchronous operation. Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::completion_key.

virtual u_long ACE_Asynch_Result_Impl::error (  void    )  const [pure virtual]

Error value if the operation fail. Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::error.

virtual ACE_HANDLE ACE_Asynch_Result_Impl::event (  void    )  const [pure virtual]

Event associated with the OVERLAPPED structure. Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::event.

virtual u_long ACE_Asynch_Result_Impl::offset (  void    )  const [pure virtual]

This really make sense only when doing file I/O. Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::offset.

virtual u_long ACE_Asynch_Result_Impl::offset_high (  void    )  const [pure virtual]

Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::offset_high.

virtual int ACE_Asynch_Result_Impl::post_completion (  ACE_Proactor_Impl *    proactor )  [pure virtual]

Post <this> to the Proactor's completion port. Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Proactor_Handle_Timeout_Upcall::timeout.

virtual int ACE_Asynch_Result_Impl::priority (  void    )  const [pure virtual]

Priority of the operation. Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::priority.

virtual int ACE_Asynch_Result_Impl::signal_number (  void    )  const [pure virtual]

POSIX4 real-time signal number to be used for the operation. <signal_number> ranges from SIGRTMIN to SIGRTMAX. By default, SIGRTMIN is used to issue <aio_> calls. This is a no-op on non-POSIX4 systems and returns 0. Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::signal_number.

virtual int ACE_Asynch_Result_Impl::success (  void    )  const [pure virtual]

Did the operation succeed? Implemented in ACE_POSIX_Asynch_Result. Referenced by ACE_Asynch_Result::success.
