Member Function Documentation

virtual const void* ACE_Asynch_Result_Impl::act

(

void

)

const [pure virtual]

ACT associated with the operation.

Implemented in ACE_POSIX_Asynch_Result.

virtual size_t ACE_Asynch_Result_Impl::bytes_transferred

(

void

)

const [pure virtual]

Number of bytes transferred by the operation.

Implemented in ACE_POSIX_Asynch_Result.

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_Read_Dgram_Result, ACE_POSIX_Asynch_Write_Dgram_Result, ACE_POSIX_Asynch_Transmit_File_Result, ACE_POSIX_Asynch_Connect_Result, ACE_POSIX_Asynch_Timer, ACE_POSIX_Asynch_Accept_Result, ACE_POSIX_Asynch_Write_File_Result, ACE_POSIX_Asynch_Read_File_Result, ACE_POSIX_Asynch_Write_Stream_Result, ACE_POSIX_Asynch_Read_Stream_Result, and ACE_POSIX_Wakeup_Completion.

virtual const void* ACE_Asynch_Result_Impl::completion_key

(

void

)

const [pure virtual]

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

Implemented in ACE_POSIX_Asynch_Result.

virtual u_long ACE_Asynch_Result_Impl::error

(

void

)

const [pure virtual]

Error value if the operation fail.

Implemented in ACE_POSIX_Asynch_Result.

virtual ACE_HANDLE ACE_Asynch_Result_Impl::event

(

void

)

const [pure virtual]

Event associated with the OVERLAPPED structure.

Implemented in ACE_POSIX_Asynch_Result.

virtual u_long ACE_Asynch_Result_Impl::offset

(

void

)

const [pure virtual]

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

Implemented in ACE_POSIX_Asynch_Result.

virtual u_long ACE_Asynch_Result_Impl::offset_high

(

void

)

const [pure virtual]

Implemented in ACE_POSIX_Asynch_Result.

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.

virtual int ACE_Asynch_Result_Impl::priority

(

void

)

const [pure virtual]

Priority of the operation.

Implemented in ACE_POSIX_Asynch_Result.

virtual int ACE_Asynch_Result_Impl::signal_number

(

void

)

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.

virtual int ACE_Asynch_Result_Impl::success

(

void

)

const [pure virtual]

Did the operation succeed?

Implemented in ACE_POSIX_Asynch_Result.
