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.
