| ACE_POSIX_Asynch_Result::~ACE_POSIX_Asynch_Result | ( | void | ) | [virtual] |

| ACE_BEGIN_VERSIONED_NAMESPACE_DECL size_t ACE_POSIX_Asynch_Result::bytes_transferred | ( | void | ) | const [virtual] |
| const void * ACE_POSIX_Asynch_Result::completion_key | ( | void | ) | const [virtual] |
This is the ACT associated with the handle on which the Asynch_Operation takes place.
@ This is not implemented for POSIX4 platforms.
Implements ACE_Asynch_Result_Impl.
| u_long ACE_POSIX_Asynch_Result::error | ( | void | ) | const [virtual] |
| ACE_HANDLE ACE_POSIX_Asynch_Result::event | ( | void | ) | const [virtual] |
| u_long ACE_POSIX_Asynch_Result::offset | ( | void | ) | const [virtual] |
This really make sense only when doing file I/O.
@ On POSIX4-Unix, offset_high should be supported using aiocb64.
Implements ACE_Asynch_Result_Impl.
| u_long ACE_POSIX_Asynch_Result::offset_high | ( | void | ) | const [virtual] |
Implements ACE_Asynch_Result_Impl.
| int ACE_POSIX_Asynch_Result::post_completion | ( | ACE_Proactor_Impl * | proactor | ) | [virtual] |
| int ACE_POSIX_Asynch_Result::priority | ( | void | ) | const [virtual] |
| void ACE_POSIX_Asynch_Result::set_bytes_transferred | ( | size_t | nbytes | ) |
Simulate value to use in the post_completion ().
| void ACE_POSIX_Asynch_Result::set_error | ( | u_long | errcode | ) |
Simulate error value to use in the post_completion ().
| int ACE_POSIX_Asynch_Result::signal_number | ( | void | ) | const [virtual] |
POSIX4 realtime signal number to be used for the operation. <signal_number> ranges from SIGRTMIN to SIGRTMAX. By default, SIGRTMIN is used to issue <aio_> calls.
Implements ACE_Asynch_Result_Impl.
| int ACE_POSIX_Asynch_Result::success | ( | void | ) | const [virtual] |
const void* ACE_POSIX_Asynch_Result::act_ [protected] |
ACT for this operation. We could use <aiocb::aio_sigevent.sigev_value.sival_ptr> for this. But it doesnot provide the constness, so this may be better.
size_t ACE_POSIX_Asynch_Result::bytes_transferred_ [protected] |
Bytes transferred by this operation.
const void* ACE_POSIX_Asynch_Result::completion_key_ [protected] |
ACT associated with handle.
u_long ACE_POSIX_Asynch_Result::error_ [protected] |
Error if operation failed.
Handler that will be called back.
int ACE_POSIX_Asynch_Result::success_ [protected] |
Success indicator.
