Do-nothing constructor.

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.

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.

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

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

Error value if the operation fail.

Implemented in ACE_POSIX_Asynch_Result.

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

Event associated with the OVERLAPPED structure.

Implemented in ACE_POSIX_Asynch_Result.

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.

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

Implemented in ACE_POSIX_Asynch_Result.

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.

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

Priority of the operation.

Implemented in ACE_POSIX_Asynch_Result.

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.

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

Did the operation succeed?

Implemented in ACE_POSIX_Asynch_Result.
