hi all:
what's the usage of ev_pncalls in struct event? why not direct
use ev_ncalls?
two question:
1. in libevent 1.4.14, it seems only used in event_process_active(),
but in libeven2 it used in event_signal_closure. why?
2. ev->ev_pncalls = &ncalls; // from event_process_active()
here, ncalls is a stack variable.
if (ev->ev_ncalls && ev->ev_pncalls) {
/* Abort loop */
*ev->ev_pncalls = 0; // ev.ev_pncalls point to a
stack variable, will this cover the stack?
}
thanks!
