Would be very useful for IntelliJ to have the ability to generate C callbacks in a Kotlin Native project. Lets say hypothetically these definitions exist in a Kotlin Native library:

// ...
interface ApplicationBase {
    // ...
    fun connectActivateSignal(slot: CPointer<CFunction<(app: CPointer<GApplication>, userData: gpointer) -> Unit>>,
                              userData: gpointer): ULong =
        connectGtkSignal(obj = gAppPtr, signal = "activate", slot = slot, data = userData)
}

class Application(val id: String) : ApplicationBase {
    // ...
}

And a hypothetical Kotlin Native program is developed where a Kotliner starts typing in the following with the carrot positioned in the parenthesis:

val app = Application("org.example.sampleapp")
app.connectActivateSignal()

Hypothetically in that situation IntelliJ would have a light bulb appear containing the option to generate a C callback. When the option is selected IntelliJ generates a callback and the Kotliner enters in the function name (eg activateApplication):

private fun activateApplication(app: CPointer<GApplication>, userData: gpointer) {
    TODO("Implement this C callback")
}

Next IntellIJ changes app.connectActivateSignal() to connectActivateSignal(staticCFunction(::activateApplication)) and inserts the import for staticCFunction .
