An OO event demultiplexor and event handler dispatcher for Win32 <MsgWaitForMultipleObjects>.
The ACE_Msg_WFMO_Reactor is an OO event demultiplexor and event handler Reactor. It differs from <ACE_WFMO_Reactor> by its ability to react on Windows messages. It is needed when the task should serve also as a COM/DCOM server.
ACE_Msg_WFMO_Reactor::ACE_Msg_WFMO_Reactor | ( | ACE_Sig_Handler * | sh = 0 , |
ACE_Timer_Queue * | tq = 0 |
||
) |
Initialize <ACE_Msg_WFMO_Reactor> with the default size.
ACE_Msg_WFMO_Reactor::ACE_Msg_WFMO_Reactor | ( | size_t | size, |
int | unused = 0 , |

ACE_Sig_Handler * | sh = 0 , |
||
ACE_Timer_Queue * | tq = 0 |
||
) |
Initialize <ACE_Msg_WFMO_Reactor> with size size. Two slots will be added to the size parameter which will store handles used for internal management purposes.

This event loop driver blocks for up to max_wait_time before returning. It will return earlier if timer events, I/O events, window events, or signal events occur. Note that max_wait_time can be 0, in which case this method blocks indefinitely until events occur.
max_wait_time is decremented to reflect how much time this call took. For instance, if a time value of 3 seconds is passed to handle_events and an event occurs after 2 seconds, max_wait_time will equal 1 second. This can be used if an application wishes to handle events for some fixed amount of time.
<MsgWaitForMultipleObjects> is used as the demultiplexing call
Returns the total number of ACE_Event_Handlers that were dispatched, 0 if the max_wait_time elapsed without dispatching any handlers, or -1 if an error occurs.
The only difference between <alertable_handle_events> and <handle_events> is that in the alertable case, MWMO_ALERTABLE is passed to <MsgWaitForMultipleObjects> for the <bAlertable> option.

This method is just like the one above, except the max_wait_time value is a reference and can therefore never be NULL.
