Detailed Description

This is that class which will be passed back to the <handler> when the asynchronous accept completes.

This class has all the information necessary for the <handler> to uniquiely identify the completion of the asynchronous accept.

Member Function Documentation

ACE_HANDLE ACE_POSIX_Asynch_Accept_Result::accept_handle ( void ) const
 

I/O handle for the new connection.

const void * ACE_POSIX_Asynch_Accept_Result::act ( void ) const
 

ACT associated with the operation.

Reimplemented from ACE_POSIX_Asynch_Result.

u_long ACE_POSIX_Asynch_Accept_Result::bytes_to_read ( void ) const
 

The number of bytes which were requested at the start of the asynchronous accept.

u_long ACE_POSIX_Asynch_Accept_Result::bytes_transferred ( void ) const
 

Number of bytes transferred by the operation.

Reimplemented from ACE_POSIX_Asynch_Result.

void ACE_POSIX_Asynch_Accept_Result::complete ( u_long bytes_transferred,
int success,
const void * completion_key,
u_long error ) [protected, virtual]
 

ACE_Proactor will call this method when the accept completes.

const void * ACE_POSIX_Asynch_Accept_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.

Reimplemented from ACE_POSIX_Asynch_Result.

u_long ACE_POSIX_Asynch_Accept_Result::error ( void ) const
 

Error value if the operation fail.

Reimplemented from ACE_POSIX_Asynch_Result.

ACE_HANDLE ACE_POSIX_Asynch_Accept_Result::event ( void ) const
 

This returns ACE_INVALID_HANDLE on POSIX4 platforms.

Reimplemented from ACE_POSIX_Asynch_Result.

ACE_HANDLE ACE_POSIX_Asynch_Accept_Result::listen_handle ( void ) const
 

I/O handle used for accepting new connections.

ACE_Message_Block & ACE_POSIX_Asynch_Accept_Result::message_block ( void ) const
 

Message block which contains the read data.

u_long ACE_POSIX_Asynch_Accept_Result::offset ( void ) const
 

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

@ On POSIX4-Unix, offset_high should be supported using aiocb64.

Reimplemented from ACE_POSIX_Asynch_Result.

u_long ACE_POSIX_Asynch_Accept_Result::offset_high ( void ) const
 

Reimplemented from ACE_POSIX_Asynch_Result.

int ACE_POSIX_Asynch_Accept_Result::post_completion ( ACE_Proactor_Impl * proactor )
 

Post <this> to the Proactor.

Reimplemented from ACE_POSIX_Asynch_Result.

int ACE_POSIX_Asynch_Accept_Result::priority ( void ) const
 

The priority of the asynchronous operation.

Reimplemented from ACE_POSIX_Asynch_Result.

int ACE_POSIX_Asynch_Accept_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 calls. This is a no-op on non-POSIX4 systems and returns 0.

Reimplemented from ACE_POSIX_Asynch_Result.

int ACE_POSIX_Asynch_Accept_Result::success ( void ) const
 

Did the operation succeed?

Reimplemented from ACE_POSIX_Asynch_Result.
