Also how can I pass a function as a parameter via C?

[Artyom Degtyarev [JB]]

You mean, Kotlin function? Like here(https://github.com/JetBrains/kotlin-native/blob/master/INTEROP.md#callbacks)

No, I want to pass a C function as a parameter to a Kotlin function.

If I have a Kotlin function that looks like this: fun test(param1: () -> Unit) {...} how would I create a C function and pass it as a parameter?

I am talking about exporting my project as a dynamic library

[Artyom Degtyarev [JB]]

Please have a look at this, I hope that I understood you correctly:

Kotlin code:
fun execCFunction(cFunc: CFunction<() -> Unit>){
    cFunc.ptr.invoke()
}

C code:
void printThings() {
    printf("IM INVOKED FROM KOTLIN !\n");
}
int main() {
    dynamic_ExportedSymbols* lib = dynamic_symbols();
    lib->kotlin.root.sample.execCFunction(&printThings);
    return 0;
}

Yes, exactly!

[Patrick]

Is that how I can do it, or just for clarification?

[Artyom Degtyarev [JB]]

Yep, this one worked for me, so give it a try.

This works, thank you so much 🙂
