Re: [Vala] Delegates thread-safe

[Alexandre Rosenfeld <alexandre rosenfeld gmail com>]

Hm, interesting, how would I do that?

I have a generator function that uses the delegate as such:

public void generator(GeneratorCallback callback) {
 Thread.create<void*>(() => {
                        Individual? individual = callback();
                        queue.push(individual);
 return null;
}, true);
}

And my delegate is declared as:

delegate Individual GeneratorCallback();


I tried using *owned* in *generator *but it didnt help. It crashes when
calling callback.

Any help?

Regards,
Alexandre
