Probably, except you never actually wait on the event! :-) (or maybe I missed it).
I'm assuming you mean to wait on it after the 'waiting' thread creates it if it doesn't exist:
if(!counted) { BOOST_INTERLOCKED_INCREMENT(&flag.count); counted=true; status=::boost::detail::interlocked_read_acquire(&flag.status); if(status==function_complete_flag_value) { break; }
event_handle=::boost::detail::interlocked_read_acquire(&flag.event_handle); if(!event_handle) {
event_handle=::boost::detail::allocate_event_handle(flag.event_handle); continue; } ***** Wait(event_handle); ****** ? }
Or not quite there, because of the 'continue', but somewhere around there. (?)
