Detailed Description

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

Once <open> is called, multiple asynchronous <accept>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 <ACE_Handler::handle_accept> callback.

Member Function Documentation

int ACE_WIN32_Asynch_Accept::accept ACE_Message_Block message_block,
size_t  bytes_to_read,
ACE_HANDLE  accept_handle,
const void *  act,
int  priority,
int  signal_number = 0
[virtual]
 

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 <accept_handle> will be used for the <accept> call. If (<accept_handle> == 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.

Implements ACE_Asynch_Accept_Impl.

int ACE_WIN32_Asynch_Accept::cancel void   )  [virtual]
 

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
[virtual]
 

Initializes the factory with information which will be used with each asynchronous call. If (<handle> == ACE_INVALID_HANDLE), <ACE_Handler::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 [virtual]
 

Return the underlying proactor.

Reimplemented from ACE_WIN32_Asynch_Operation.
