Detailed Description

This class provides concrete implementation for ACE_Asynch_Result for POSIX4 platforms. This class extends aiocb and makes it more useful.

Constructor & Destructor Documentation

ACE_POSIX_Asynch_Result::~ACE_POSIX_Asynch_Result (  void    )  [virtual]

Destructor.

ACE_POSIX_Asynch_Result::ACE_POSIX_Asynch_Result (  ACE_Handler &    handler, const void *    act, ACE_HANDLE    event, u_long    offset, u_long    offset_high, int    priority, int    signal_number )  [protected]

Constructor. <Event> is not used on POSIX.

Member Function Documentation

const void * ACE_POSIX_Asynch_Result::act (  void    )  const [virtual]

ACT associated with the operation. Implements ACE_Asynch_Result_Impl.

size_t ACE_POSIX_Asynch_Result::bytes_transferred (  void    )  const [virtual]

Number of bytes transferred by the operation. Implements ACE_Asynch_Result_Impl.

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]

Error value if the operation fail. Implements ACE_Asynch_Result_Impl.

ACE_HANDLE ACE_POSIX_Asynch_Result::event (  void    )  const [virtual]

This returns ACE_INVALID_HANDLE on POSIX4 platforms. Implements ACE_Asynch_Result_Impl.

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]

Post <this> to the Proactor. Implements ACE_Asynch_Result_Impl.

int ACE_POSIX_Asynch_Result::priority (  void    )  const [virtual]

Priority of the operation. Implements ACE_Asynch_Result_Impl.

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]

Did the operation succeed? Implements ACE_Asynch_Result_Impl.

Member Data Documentation

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.

ACE_Handler& ACE_POSIX_Asynch_Result::handler_ [protected]

Handler that will be called back.

int ACE_POSIX_Asynch_Result::success_ [protected]

Success indicator.
