Detailed Description

This class is a factory for starting off asynchronous accepts on a listen handle.

Once <open> is called, multiple asynchronous s can started using this class. A ACE_Asynch_Accept::Result will be passed back to the <handler> when the asynchronous accept completes through the callback.


Constructor & Destructor Documentation

ACE_WIN32_Asynch_Accept::ACE_WIN32_Asynch_Accept ( ACE_WIN32_Proactor * win32_proactor )
 

Constructor.

ACE_WIN32_Asynch_Accept::~ACE_WIN32_Asynch_Accept ( void )
 

Destructor.


Member Function Documentation

int ACE_WIN32_Asynch_Accept::accept ( ACE_Message_Block & message_block,
u_long bytes_to_read,
ACE_HANDLE accept_handle,
const void * act,
int priority,
int signal_number = 0 )
 

This starts off an asynchronous accept. The asynchronous accept call also allows any initial data to be returned to the <handler>. Upto <bytes_to_read> will be read and stored in the <message_block>. The will be used for the call. If ( == INVALID_HANDLE), a new handle will be created.

<message_block> must be specified. This is because the address of the new connection is placed at the end of this buffer.

int ACE_WIN32_Asynch_Accept::cancel ( void )
 

This cancels all pending accepts operations that were issued by the calling thread. The function does not cancel asynchronous operations issued by other threads.

Reimplemented from ACE_WIN32_Asynch_Operation.

int ACE_WIN32_Asynch_Accept::open ( ACE_Handler & handler,
ACE_HANDLE handle,
const void * completion_key,
ACE_Proactor * proactor )
 

Initializes the factory with information which will be used with each asynchronous call. If (<handle> == ACE_INVALID_HANDLE), will be called on the <handler> to get the correct handle.

Reimplemented from ACE_WIN32_Asynch_Operation.

ACE_Proactor * ACE_WIN32_Asynch_Accept::proactor ( void ) const
 

Return the underlying proactor.

Reimplemented from ACE_WIN32_Asynch_Operation.
