I need to convert Int to ByteArray . .toByte() gives only first 8 bits, but I need a whole number. usePinned looks like what I need, but it’s unreachable in the commonMain

I'm using this to convert Long to ByteArray. Perhaps it could be adapted to your needs?

private fun Long.toByteArray(): ByteArray {
    val data = ByteArray(8)
    var i = 0
    data[i++] = (this ushr 56 and 0xffL).toByte()
    data[i++] = (this ushr 48 and 0xffL).toByte()
    data[i++] = (this ushr 40 and 0xffL).toByte()
    data[i++] = (this ushr 32 and 0xffL).toByte()
    data[i++] = (this ushr 24 and 0xffL).toByte()
    data[i++] = (this ushr 16 and 0xffL).toByte()
    data[i++] = (this ushr  8 and 0xffL).toByte() // ktlint-disable no-multi-spaces
    data[i]   = (this         and 0xffL).toByte() // ktlint-disable no-multi-spaces
    return data
}

yeah, probably I need something like this, hoped there’s a built in way to do so, thanks
