ACE_Select_Reactor to manage
max_number_of_handles.  If restart is non-0 then the
ACE_Reactor's handle_events method will be restarted
automatically when EINTR occurs.  If signal_handler or
timer_queue are non-0 they are used as the signal handler and
timer queue, respectively.  If disable_notify_pipe is non-0 the
notification pipe is not created, thereby saving two I/O handles.

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_Handlers
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.
virtual int handle_events (ACE_Time_Value &max_wait_time);

max_wait_time value is a reference and can therefore never be

underlying I/O handle.
virtual int register_handler (
    ACE_HANDLE handle,

    );
eh with a particular mask.  Note that since the
handle is given the Select_Reactor will *not* call
eh-get_handle() to extract the underlying I/O handle.
Originally this interface was available for all platforms, but because ACE_HANDLE is an int on non-Win32 platforms, compilers are not able to tell the difference between register_handler(ACE_Event_Handler*,ACE_Reactor_Mask) and register_handler(ACE_Event_Handler*,ACE_HANDLE). Therefore, we have restricted this method to Win32 only.

    ACE_Sig_Action *new_disp = 0,
    ACE_Event_Handler **old_sh = 0,
    ACE_Sig_Action *old_disp = 0
    );
new_sh to handle the signal signum using the
new_disp.  Returns the old_sh that was previously registered
(if any), along with the old_disp of the signal handler.
virtual int register_handler (
    const ACE_Sig_Set &sigset,
    ACE_Event_Handler *new_sh,
    ACE_Sig_Action *new_disp = 0
    );
new_sh to handle a set of signals sigset using the
new_disp.
virtual int remove_handler (
    ACE_Event_Handler *eh,
    ACE_Reactor_Mask mask
    );
mask binding of eh from the Select_Reactor.  If
there are no more bindings for this eh then it is removed from
the Select_Reactor.  Note that the Select_Reactor will call
eh-get_handle() to extract the underlying I/O handle.
virtual int remove_handler (ACE_HANDLE handle, ACE_Reactor_Mask);
mask bind of Event_Handler whose handle is
handle from the Select_Reactor.  If there are no more bindings
for this eh then it is removed from the Select_Reactor.
virtual int remove_handler (
    const ACE_Handle_Set &handle_set,
    ACE_Reactor_Mask
    );
mask bindings for handles in the handle_set
bind of Event_Handler.  If there are no more bindings for any
of these handlers then they are removed from the Select_Reactor.

    int signum,
    ACE_Sig_Action *new_disp,
    ACE_Sig_Action *old_disp = 0,

    );
signum.
sigkey is ignored in this implementation since there is only
one instance of a signal handler.  Install the new disposition
(if given) and return the previous disposition (if desired by the
caller).  Returns 0 on success and -1 if signum is invalid.
virtual int remove_handler (const ACE_Sig_Set &sigset);
remove_handler for every signal in sigset.
virtual int suspend_handler (ACE_Event_Handler *eh);
Event_Handler associated with eh.
virtual int suspend_handler (ACE_HANDLE handle);

virtual int suspend_handler (const ACE_Handle_Set &handles);

virtual int suspend_handlers (void);

virtual int resume_handler (ACE_Event_Handler *eh);

virtual int resume_handler (ACE_HANDLE handle);
Event_Handler associated with

virtual int resume_handler (const ACE_Handle_Set &handles);

    ACE_Event_Handler *,
    const void *arg,
    const ACE_Time_Value &delta_time,
    const ACE_Time_Value &interval = ACE_Time_Value::zero
    );
event_handler that will expire after delta_time
amount of time.  If it expires then arg is passed in as the
value to the event_handler's handle_timeout callback method.
If interval is != to ACE_Time_Value::zero then it is used to
reschedule the event_handler automatically.  This method
returns a timer_id that uniquely identifies the event_handler
in an internal list.  This timer_id can be used to cancel an
event_handler before it expires.  The cancellation ensures that
timer_ids are unique up to values of greater than 2 billion
timers.  As long as timers don't stay around longer than this
there should be no problems with accidentally deleting the wrong
timer.  Returns -1 on failure (which is guaranteed never to be a
valid timer_id.
virtual int cancel_timer (
    ACE_Event_Handler *event_handler,
    int dont_call_handle_close = 1
    );
event_handlers that match the address of
event_handler.  If dont_call_handle_close is 0 then the
handle_close method of event_handler will be invoked.
Returns number of handler's cancelled.
virtual int cancel_timer (
    long timer_id,
    const void **arg = 0,
    int dont_call_handle_close = 1
    );
ACE_Event_Handler that matches the timer_id
value (which was returned from the schedule method).  If arg is
non-NULL then it will be set to point to the ``magic cookie''
argument passed in when the Event_Handler was registered.  This
makes it possible to free up the memory and avoid memory leaks.
If dont_call_handle_close is 0 then the handle_close method
of event_handler will be invoked.  Returns 1 if cancellation
succeeded and 0 if the timer_id wasn't found.
virtual int schedule_wakeup (
    ACE_Event_Handler *eh,

virtual int notify (
    ACE_Event_Handler * = 0,
    ACE_Reactor_Mask = ACE_Event_Handler::EXCEPT_MASK,
    ACE_Time_Value * = 0
    );
ACE_Select_Reactor if currently blocked in
select()/poll().  Pass over both the Event_Handler *and* the
mask to allow the caller to dictate which Event_Handler
method the Select_Reactor will invoke.  The ACE_Time_Value
indicates how long to blocking trying to notify the
Select_Reactor.  If timeout == 0, the caller will block until
action is possible, else will wait until the relative time
specified in *timeout elapses).
virtual void max_notify_iterations (int);
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.
virtual int max_notify_iterations (void);
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.
