[Ace-users] [ace-users] ACE_Select_Reactor not calling handle_output( )

[p_j_r_m]

After reading more about ACE_Reactor, I have seen  that  after the schedule_xxx ( ) functions are called the reactor does not  notice the mask changes until a new event comes. So I have put a notify( ) after each schedule call so reactor will re-examine the mask inmediatly, but the problem is the same: handle_output( ) is not called.
I've also tryed to register()/unregister() my event handler at the right points with the right mask, with the same result.
Also, I have checked the TP_Reactor_Test example, which does the same  things for schedule functions (although with a thread pool) and it seems to work.

What else should I try for my simple test program?
 
Thank you

Ok.

Right, this is expected when using schedule_wakeup() and
cancel_wakeup(). Please see C++NPv2 section 3.5 for why this is and
what you need to do to have your events handled as you want.

For more info on C++NPv2, please see
