Re: [Boost-users] Boost.Signals2 - if slot (functor of lambda) destructs the signal, calling the slot itself -> safe for functor?

Oh and an absolute basics question...

Does the connect function copy functors?
I believe it does, so the code below would be safe.
(Is that correct????)

Thanks

boost::signals2::signal<void()> sig;
{
   Slot_Functor slot;
   sig.connect(slot);
}
sig();

Is there any case, where a slot could go out of scope before the
signal is called??
If functors (and lambdas) are nicely copied, then I believe that the
slot will always be in scope when it is called.
(??)

Thanks
