I think that this is called a function reference but I’m not sure.
Anyway, this works:
def start_link(_arg) do
Task.start_link(&check_updates/0)
end
But what if check_updates requires a parameter? So it would be check_updates/1. How can I call it in Tasks.start_link function?
Where Next?

fn () -> check_updates(whatever) endOvermindDL1
Then you’d have to use an anonymous function instead:

To be picky
&check_updates/1is actually just syntactic sugar forfn (x) -> check_updates(x) end. All the&capture operator does is transform to an anonymous function. It has some syntax limitations when using it to include arguments, for example when you wanted to create an anonymous function with 0 arguments.
