How can I pass a Kotlin String to a C function?

[dany]

depends on your c function signature but you can find info here: https://github.com/JetBrains/kotlin-native/blob/master/INTEROP.md#working-with-the-strings

I got a function that takes a char * as a param, Insted of using the .cstr everytime im using the function inside Kotlin, I just want to pass it in advance

not sure what exactly you’re trying to achieve, but aString.cstr.getPointer(arena) will produce a C pointer with lifetime bound to certain arena
