Member Function Documentation

act()

virtual const void * ACE_Asynch_Result_Impl::act ( ) const

pure virtual

ACT associated with the operation.

Implemented in ACE_POSIX_Asynch_Result.

bytes_transferred()

virtual size_t ACE_Asynch_Result_Impl::bytes_transferred ( ) const

pure virtual

Number of bytes transferred by the operation.

Implemented in ACE_POSIX_Asynch_Result.

complete()

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_Accept_Result, ACE_POSIX_Asynch_Connect_Result, ACE_POSIX_Asynch_Read_Dgram_Result, ACE_POSIX_Asynch_Read_File_Result, ACE_POSIX_Asynch_Read_Stream_Result, ACE_POSIX_Asynch_Timer, ACE_POSIX_Asynch_Transmit_File_Result, ACE_POSIX_Asynch_Write_Dgram_Result, ACE_POSIX_Asynch_Write_File_Result, ACE_POSIX_Asynch_Write_Stream_Result, and ACE_POSIX_Wakeup_Completion.

completion_key()

virtual const void * ACE_Asynch_Result_Impl::completion_key ( ) const

pure virtual

This ACT is not the same as the ACT associated with the asynchronous operation.

Implemented in ACE_POSIX_Asynch_Result.

error()

virtual u_long ACE_Asynch_Result_Impl::error ( ) const

pure virtual

Error value if the operation fail.

Implemented in ACE_POSIX_Asynch_Result.

event()

virtual ACE_HANDLE ACE_Asynch_Result_Impl::event ( ) const

pure virtual

Event associated with the OVERLAPPED structure.

Implemented in ACE_POSIX_Asynch_Result.

offset()

virtual u_long ACE_Asynch_Result_Impl::offset ( ) const

pure virtual

This really make sense only when doing file I/O.

Implemented in ACE_POSIX_Asynch_Result.

offset_high()

virtual u_long ACE_Asynch_Result_Impl::offset_high ( ) const

pure virtual

Implemented in ACE_POSIX_Asynch_Result.

post_completion()

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.

priority()

virtual int ACE_Asynch_Result_Impl::priority ( ) const

pure virtual

Priority of the operation.

Implemented in ACE_POSIX_Asynch_Result.

signal_number()

virtual int ACE_Asynch_Result_Impl::signal_number ( ) 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.

success()

virtual int ACE_Asynch_Result_Impl::success ( ) const

pure virtual

Did the operation succeed?

Implemented in ACE_POSIX_Asynch_Result.
