How can I call Windows api such GetVersion, GetSerialNumber ? I have not found these functions.

You can try to use cinterop to generate bindings onto the sysinfoapi.h header including them, and then use it.

GetVersion() exists in platform.windows. Apparently deprecated in newer Windows versions though according to https://docs.microsoft.com/en-us/windows/win32/api/sysinfoapi/nf-sysinfoapi-getversion

Thanks! I've created sysinfoapi.def and have found GetVersion() etc

[aleksey.tomin]

But result....

val version = GetVersion().toLong()
        val version0 = version.toByte()
        val version1 = (version / 256).toByte()
        val version2 = (version / 65536).toShort()
        println("$version/${version.toString(16)} - ${version0}.${version1}.${version2}")

Result:
602931718/23f00206 - 6.2.9200
But...

C:\>cmd /c ver

Microsoft Windows [Version 10.0.18363.836]

Why 6.2 instead of 10.0?

[Artyom Degtyarev [JB]]

This can be the reason. From the Microsoft documentation above:

Applications not manifested for Windows 8.1 or Windows 10 will return the Windows 8 OS version value (6.2).

But new methods will not return version - olny "Is...Or...". How can I get windows version?

[Artyom Degtyarev [JB]]

It seems to be a Windows API question rather than a Kotlin/Native one. I’ve read through this, and maybe you can use this approach: to get system version via the file information of your system DLLs. Why wouldn’t you try going with IsWindows10OrGreater?

Thank you!
