How do one print to the stderr in K/N?

[olonho]

import platform.posix.*

fun main(args: Array<String>) {
   fprintf(stderr, "Hi\n")
}

Thanks! Any way to do that in platform independend way like print (e.g. printerr)?

[olonho]

It is relatively platform-independent (will work on Linux mac and Windows)

[fitzoh]

How about the other kind of platform-independent (jvm/js/native)?

[olonho]

not sure what would it mean on JS for example, and in general it likely shall be something in target dependent portability layer

[gildor]

On JS it will be console.error(), System.err on JVM

[olonho]

Generally K/N is not trying to abstract out platform facilities, unlike Java, so we not planning to provide portable methods for doing everything in stock libraries, although nothing prevents development of abstraction layers like that externally.

Hi, thanks for the tip. I just had to change stderr to __stderrp (did take me a while 🙂 )

maybe makes sense to contribute into .def file for your platform with wrapper making stderr available under expected name, see similar logic for zlib: https://github.com/JetBrains/kotlin-native/blob/0fed84a2cdbf6685b54b5059dc03853b954b9456/platformLibs/src/platform/osx/zlib.def#L31
