Get the event handle.

|
Called when object is removed from the ACE_Reactor.
Reimplemented from ACE_Event_Handler. |
|
Dispatch a single set of events. If <milli_seconds> elapses before any events occur, return 0. Return 1 if a completion is dispatched. Return -1 on errors. |
|
Block indefinitely until at least one event is dispatched. Dispatch a single set of events. If <wait_time> elapses before any events occur, return 0. Return 1 on success i.e., when a completion is dispatched, non-zero (-1) on errors and errno is set accordingly. Implements ACE_Proactor_Impl. |

|
Set number of thread used as a parameter to CreatIoCompletionPort.
Implements ACE_Proactor_Impl. |
|
Get number of thread used as a parameter to CreatIoCompletionPort.
Implements ACE_Proactor_Impl. |
|
Post a result to the completion port of the Proactor. If errors occur, the result will be deleted by this method. If successful, the result will be deleted by the Proactor when the result is removed from the completion port. Therefore, the result should have been dynamically allocated and should be orphaned by the user once this method is called. |
|
Post <how_many> completions to the completion port so that all threads can wake up. This is used in conjunction with the <run_event_loop>. Implements ACE_Proactor_Impl. |
|
This method adds the <handle> to the I/O completion port. This function is a no-op function for Unix systems. Implements ACE_Proactor_Impl. |
|
Add wakeup dispatch threads (reinit).
Implements ACE_Proactor_Impl. |
|
|
|
Handle for the completion port. Unix doesnt have completion ports. |
|
This event is used in conjunction with Reactor when we try to integrate the event loops of Reactor and the Proactor. |
|
This number is passed to the <CreatIOCompletionPort> system call. |
|
Pseudo-task for asynch connect ( NT/2000) In future should removed in XP with ConnectEx support |
|
Flag that indicates whether we are used in conjunction with Reactor. |
|
Handler to handle the wakeups. This works in conjunction with the <ACE_Proactor::run_event_loop>. |
