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] |
This is called when the asynchronous operation completes.
Implemented in ACE_POSIX_Asynch_Read_Stream_Result, ACE_POSIX_Asynch_Write_Stream_Result, ACE_POSIX_Asynch_Read_File_Result, ACE_POSIX_Asynch_Write_File_Result, ACE_POSIX_Asynch_Accept_Result, ACE_POSIX_Asynch_Connect_Result, ACE_POSIX_Asynch_Transmit_File_Result, ACE_POSIX_Asynch_Write_Dgram_Result, ACE_POSIX_Asynch_Read_Dgram_Result, ACE_POSIX_Wakeup_Completion, and ACE_POSIX_Asynch_Timer.
| 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.
