Scala Native - Convert Array[Byte] to Ptr[Byte]

Question

I'm trying to pass a Scala array to native code and need to do the conversion. How to convert Array[Byte] to Ptr[Byte] in Scala Native?

Answer 1

My best solution so far is this:

def makeNativeArray(input: Array[Byte])(using z: Zone): Ptr[Byte] =
  val rawSize = input.length
  val buffer = alloc[Byte](rawSize)
  for i <- 0 until rawSize
  do
    buffer(i) = input(i)
  buffer
