This is based on the C entry and works on Windows 10:
<lang scala>// Kotlin Native version 0.3
import kotlinx.cinterop.*
import win32.*
fun main(args: Array<String>) {
for (i in 0 until (80 * 25)) print("A") // fill 80 x 25 console with 'A's
println()
memScoped {
val conOut = GetStdHandle(-11)
val info = alloc<CONSOLE_SCREEN_BUFFER_INFO>()
val pos = alloc<COORD>()
GetConsoleScreenBufferInfo(conOut, info.ptr)
pos.X = (info.srWindow.Left + 3).toShort() // column number 3 of display window
pos.Y = (info.srWindow.Top + 6).toShort() // row number 6 of display window
val c = alloc<wchar_tVar>()
val len = alloc<IntVar>()
ReadConsoleOutputCharacterW(conOut, c.ptr, 1, pos.readValue(), len.ptr)
if (len.value == 1) {
val ch = c.value.toChar()
println("The character at column 3, row 6 is '$ch'")
}
else println("Something went wrong!")
}
}</lang>
{{out}}
<pre>
The character at column 3, row 6 is 'A'
