Detailed Description

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

Constructor. <Event> is not used on POSIX.

Member Function Documentation

const void * ACE_POSIX_Asynch_Result::act ( void  ) const

ACT associated with the operation.

Implements ACE_Asynch_Result_Impl.

size_t ACE_POSIX_Asynch_Result::bytes_transferred ( void  ) const

Number of bytes transferred by the operation.

Implements ACE_Asynch_Result_Impl.

const void * ACE_POSIX_Asynch_Result::completion_key ( void  ) const

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

Error value if the operation fails.

Implements ACE_Asynch_Result_Impl.

ACE_HANDLE ACE_POSIX_Asynch_Result::event ( void  ) const

This returns ACE_INVALID_HANDLE on POSIX4 platforms.

Implements ACE_Asynch_Result_Impl.

u_long ACE_POSIX_Asynch_Result::offset ( void  ) const

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
int ACE_POSIX_Asynch_Result::post_completion ( ACE_Proactor_Impl proactor)

Post this to the Proactor.

Implements ACE_Asynch_Result_Impl.

int ACE_POSIX_Asynch_Result::priority ( void  ) const

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

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

Did the operation succeed?

Implements ACE_Asynch_Result_Impl.

Member Data Documentation

const void* ACE_POSIX_Asynch_Result::act_

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_

Bytes transferred by this operation.

const void* ACE_POSIX_Asynch_Result::completion_key_

ACT associated with handle.

u_long ACE_POSIX_Asynch_Result::error_

Error if operation failed.

ACE_Handler::Proxy_Ptr ACE_POSIX_Asynch_Result::handler_proxy_

Handler that will be called back.

int ACE_POSIX_Asynch_Result::success_

Success indicator.
