when compiling the following K/N code: ``` fun foo...

when compiling the following K/N code:

fun foo(bar: IntArray) {}

to a macOsX dynamic library, I “get” a compiled library with a generated header where kotlin IntArray type is mapped to libtest_kref_kotlin_IntArray, where test is the name of my library.
There seems to be no good way of constructing this object though, or at least it’s not defined in this header. Is there a way of consuming this library in a C program and somehow providing an object of that type?

You would have to communicate with the kotlin vm somehow, since it's refcounted. Assuming that's how the GC works.

Sorry I cant answer the question

Just create in your Kotlin code constructor for an IntArray and setter for elements. We do not automatically reexport standard library.

If C code is using native ptrs, they can't be ref counted can they? So you would need to use StableRef somehow?

@olonho okay, so if I understand correctly, only primitive types are mapped and user defined constructs get bindings? I was also wondering why arrays aren’t mapped since C seems to have a good equivalent type

[olonho]

There’s no equivalent type in C

[jacek.karaskiewicz]

I meant, that instead of libtest_kref_kotlin_IntArray in my generated header, I would get int[]

[olonho]

int[] and int* are not equivalent types to IntArray
