Member Function Documentation

int ACE_WIN32_Asynch_Connect::cancel (  void    )  [virtual]

Cancel all pending pseudo-asynchronus requests Behavior as usual AIO request Reimplemented from ACE_WIN32_Asynch_Operation.

int ACE_WIN32_Asynch_Connect::cancel_uncompleted (  int    flg_notify, ACE_Handle_Set &    set )  [private]

Cancel uncompleted connect operations. Parameters: flg_notify  Indicates whether or not to send notification about canceled connect operations. If 0, don't send notifications. If 1, notify user about canceled connects. According WIN32 standards we should receive notifications on canceled AIO requests. set  Receives the set of I/O handles on which asynchronous connect requests were canceled as a result of this method. The contents of set are completely replaced.

int ACE_WIN32_Asynch_Connect::close (  void    )

Close performs cancellation of all pending requests and close the connect handle

int ACE_WIN32_Asynch_Connect::connect (  ACE_HANDLE    connect_handle, const ACE_Addr &    remote_sap, const ACE_Addr &    local_sap, int    reuse_addr, const void *    act, int    priority, int    signal_number = 0 )  [virtual]

Start an asynchronous connect. Parameters: connect_handle  Handle to use for the connect. If the value ACE_INVALID_HANDLE, a new handle will be created. Return values: 0  Success -1  Error Implements ACE_Asynch_Connect_Impl.

int ACE_WIN32_Asynch_Connect::connect_i (  ACE_WIN32_Asynch_Connect_Result *    result, const ACE_Addr &    remote_sap, const ACE_Addr &    local_sap, int    reuse_addr )  [private]

ACE_HANDLE ACE_WIN32_Asynch_Connect::get_handle (  void    )  const [virtual]

Virtual from ACE_Event_Handler. Reimplemented from ACE_Event_Handler.

int ACE_WIN32_Asynch_Connect::handle_close (  ACE_HANDLE    handle, ACE_Reactor_Mask    close_mask )  [virtual]

Virtual from ACE_Event_Handler. Reimplemented from ACE_Event_Handler.

int ACE_WIN32_Asynch_Connect::handle_exception (  ACE_HANDLE    handle )  [virtual]

Called when an exceptional events occur (e.g., SIGURG). Reimplemented from ACE_Event_Handler.

int ACE_WIN32_Asynch_Connect::handle_input (  ACE_HANDLE    handle )  [virtual]

Virtual from ACE_Event_Handler. Reimplemented from ACE_Event_Handler.

int ACE_WIN32_Asynch_Connect::handle_output (  ACE_HANDLE    handle )  [virtual]

Called when output events are possible (e.g., when flow control abates or non-blocking connection completes). Reimplemented from ACE_Event_Handler.

int ACE_WIN32_Asynch_Connect::open (  ACE_Handler &    handler, ACE_HANDLE    handle, const void *    completion_key, ACE_Proactor *    proactor = 0 )  [virtual]

This open belongs to ACE_WIN32_Asynch_Operation. We forward this call to that method. We have put this here to avoid the compiler warnings. Reimplemented from ACE_WIN32_Asynch_Operation.

int ACE_WIN32_Asynch_Connect::post_result (  ACE_WIN32_Asynch_Connect_Result *    result, int    flg_post )  [private]

ACE_Proactor * ACE_WIN32_Asynch_Connect::proactor (  void    )  const [virtual]

Return the underlying proactor. Reimplemented from ACE_WIN32_Asynch_Operation.

void ACE_WIN32_Asynch_Connect::set_handle (  ACE_HANDLE    handle )  [virtual]

Virtual from ACE_Event_Handler. Reimplemented from ACE_Event_Handler.

Member Data Documentation

int ACE_WIN32_Asynch_Connect::flg_open_ [private]

1 - Connect is registered in ACE_Asynch_Pseudo_Task 0 - Aceept is deregisted in ACE_Asynch_Pseudo_Task

ACE_SYNCH_MUTEX ACE_WIN32_Asynch_Connect::lock_ [private]

The lock to protect the result queue which is shared. The queue is updated by main thread in the register function call and through the auxillary thread in the deregister fun. So let us mutex it.

MAP_MANAGER ACE_WIN32_Asynch_Connect::result_map_ [private]

Map of Result pointers that correspond to all the <accept>'s pending.

int ACE_WIN32_Asynch_Connect::task_lock_count_ [private]

To prevent ACE_Asynch_Pseudo_Task from deletion while we make a call to the ACE_Asynch_Pseudo_Task This is extra cost !!! we could avoid them if all applications will follow the rule: Proactor should be deleted only after deletion all AsynchOperation objects connected with it
