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.
