Hi! How can i use allocArrayOf() inside memScoped{ } to alloc array of double? I’m surprised that it works only for float.
Kotlin version 1.3.30

memScoped {
    val array = cValuesOf(0.0, 1.0).ptr
}

Is the next best thing I guess.

Yes, it works. Thank you!
Also something like this can work:

fun MemScope.allocDoubleArrayOf(vararg elements: Double): CArrayPointer<DoubleVar> {
    val cArrayPointer = allocArray<DoubleVar>(elements.size)
    elements.forEachIndexed { index, value ->
        cArrayPointer[index] = value
    }
    return cArrayPointer
}

You might as well just pin the array.

Take a look at usePinned.
