is trying to call an

ioctl

from kotlin-native, specifically

ioctl(STDOUT_FILENO, TIOCGWINSZ, &winsize)

but how does one create a winsize object?

see similar code in https://github.com/JetBrains/kotlin-native/blob/0fc1fb27e13b86e286e2eae410576d6527a6b971/samples/tetris/src/main/kotlin/Tetris.kt#L623

If you already have

ByteArray

you can use `refTo(0)`: https://github.com/madhead/seaowl/blob/master/sensor/src/main/kotlin/seaowl.kt#L45
