virtual ~ACE_Asynch_Result_Impl (void)
virtual size_t bytes_transferred (void) const =0
 Number of bytes transferred by the operation.
virtual const void * act (void) const =0
 ACT associated with the operation.
virtual int success (void) const =0
 Did the operation succeed?
virtual const void * completion_key (void) const =0
virtual u_long error (void) const =0
 Error value if the operation fail.
virtual ACE_HANDLE event (void) const =0
 Event associated with the OVERLAPPED structure.
virtual u_long offset (void) const =0
 This really make sense only when doing file I/O.
virtual u_long offset_high (void) const =0
virtual int priority (void) const =0
 Priority of the operation.
virtual int signal_number (void) const =0
virtual void complete (size_t bytes_transferred, int success, const void *completion_key, u_long error=0)=0
 This is called when the asynchronous operation completes.
virtual int post_completion (ACE_Proactor_Impl *proactor)=0
 Post this to the Proactor's completion port.

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_WIN32_Asynch_Result, ACE_WIN32_Asynch_Read_Stream_Result, ACE_WIN32_Asynch_Write_Stream_Result, ACE_WIN32_Asynch_Read_File_Result, ACE_WIN32_Asynch_Write_File_Result, ACE_WIN32_Asynch_Accept_Result, ACE_WIN32_Asynch_Connect_Result, ACE_WIN32_Asynch_Transmit_File_Result, ACE_WIN32_Asynch_Read_Dgram_Result, and ACE_WIN32_Asynch_Write_Dgram_Result.
