Does anyone have a method to get all environment variables on Native (ideally as a Map<String, String>)? I was hoping to use the `extern char **environ` but it's not available in platform.posix. Is it accessible in a different way? Do I need to set this up in a cinterop to get access?

as the man page says,

environ must be declared in the user program

(_GNU_SOURCE won't have any impact on platform.posix as it was built as part of stdlib, not in your project)

if you do declare a extern char **environ in a cinterop def file, you can map it to a Map<String, String> easily, e.g.

buildMap {
    for (i in 0..Int.MAX_VALUE) {
        val kv = environ?.get(i)?.toKString() ?: break
        this[kv.substringBefore('=')] = kv.substringAfter('=', "")
    }
}

Oh I read that part of the man page but completely glazed over "if the _GNU_SOURCE feature test macro is defined"

Thanks for setting me straight
