I would prefer something like this:

int smb_register_exit_event(void (*function) (void *data), void
*data);
BOOL smb_unregister_exit_event(int event_id);

int smb_register_idle_event(time_t interval = 0, void (*function) (time_t now, time_t interval, void *data), void *data);
BOOL smb_unregister_idle_event(int event_id);
