Hello. I'm just getting started, so have many noob questions.

How can I pass a variable to a function by reference and get the changed value?

[gildor]

There is no pointers, so you cannot pass primitive value by reference.
But you can pass an object with mutable value to a function and this function can change it.
So the same evaluation strategy as Java (and actually many other languages)

Yes, whenever you pass object to function, it is passed by reference. No difference with Kotlin/JVM or JS

I want to pass int by reference to a C function via interop.

What I did now is this:

memScoped {
   val a = alloc<IntVar>()
   call(a.ptr)
   println(a.value)
}

[goto1134]

is there any way to use kotlin Int instead of IntVar?

[goto1134]

any best practive?

[goto1134]

any way to avoid explicit allocation?

[olonho]

We plan to support local references, but currently it’s the only option
