The ACE_Select_Reactor is an object-oriented event demultiplexor and event handler dispatcher. The sources of events that the ACE_Select_Reactor waits for and dispatches includes I/O events, signals, and timer events. All public methods acquire the main ACE_Reactor_Token lock and call down to private or protected methods, which assume that the lock is held and so therefore don't (re)acquire the lock.

If disable_notify_pipe is non-0 then the reactor will not create a notification pipe, which will save two I/O handles but will elide the <notify()> feature. If mask_signals is 1 the reactor is "signal-safe" when dispatching handlers to signal events, whereas if mask_signals is 0 the reactor will be more efficient, but not signal-safe (which may be perfectly fine if your application doesn't use the reactor to handle signals).

Implements ACE_Reactor_Impl.
int ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >::handle_events | ( | ACE_Time_Value * | max_wait_time = 0 |
) | [inline, virtual] |
This event loop driver that blocks for max_wait_time before returning. It will return earlier if timer events, I/O 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.
Returns the total number of I/O and Timer ACE_Event_Handler's that were dispatched, 0 if the max_wait_time elapsed without dispatching any handlers, or -1 if something goes wrong.
Current <alertable_handle_events> is identical to <handle_events>.

Set the maximum number of times that the <ACE_Select_Reactor_Notify::handle_input> method will iterate and dispatch the <ACE_Event_Handlers> that are passed in via the notify pipe before breaking out of its <recv> loop. By default, this is set to -1, which means "iterate until the pipe is empty." Setting this to a value like "1 or 2" will increase "fairness" (and thus prevent starvation) at the expense of slightly higher dispatching overhead.
