Finding out if a trivial event has handlers

Edward Diener

When I try to find out if a trivial event has handlers, by comparing the
event to nullptr, I get compiler error C3918. So my natural question is
how does one test a trivial event for handlers ?

If you want this feature, you can't use trivial events.

Thanks. I have changed to non-trivial events with my own backing store
to get the functionality I need.

You should not use trivial events if you want to do that.
The fourth google result for that query could have told you that.
