detecting Win95/Win98/WinME

[Joel VanderWerf]

Some of the File#flock arguments do not work on Win95/Win98/WinME
(namely LOCK_SH and LOCK_NB), so I'm looking for a way to detect what
kind of windows the process is running on. RUBY_PLATFORM and rbconfig.rb
do not seem to help.

Any ideas?

How about `ver` ?

C:\>irb
irb(main):001:0> `ver`
=> "\nMicrosoft Windows 2000 [Version 5.00.2195]\n"

irb(main):001:0> `ver`

=> "\nMicrosoft Windows 2000 [Version 5.00.2195]\n"

Thanks, that does the trick.

irb(main):001:0> `ver`
=> "\nMicrosoft Windows 2000 [Version 5.00.2195]\n"

Thanks, that does the trick.

Hmmm... but that's not exactly cross-platform.
Is ver available on all flavors of Windows?

BTW: you could probably check some section of the Registry, but it's not
very straightforward in my experience.

I've tried it on ME, and Park Heesob tried it on Win2K, so now we know
it works on two.

Actually, this page suggests that it is standard:

http://www.computerhope.com/verhlp.htm

But this page is wrong about the output on ME. It says 'Windows ME
4.90.3000', but I got something like 'Windows Millenium ...'. So I'm
assuming it could be either.

I quail at the thought

ver command has been available from DOS, 2.x at least AFAIK.

However, it tells about the command interpreter but not about
the system. It can be changed by COMSPEC.

This is stolen from Moonwolf's "init.rb" file (part of the win32/winbase module).

require "Win32API"

buf = [148].pack("L")+"\0"*144
b = Win32API.new('kernel32','GetVersionExA','P','I').call(buf)
if b != 0
(size,major,minor,build,platform,version)=buf.unpack("LLLLLA128")
WINVER = (major << 8) | minor
WINVER_MAJOR = major
WINVER_MINOR = minor
WINVER_BUILD = build
WIN32_WINDOWS = WINVER
case platform
when 0 #Win32s

What about XP? I suspect it falls somewhere in the WinNT/2000 case.

Thanks. I'll keep that in mind in case the `ver` solution doesn't work
out. (Or is there a strong case for using the Win32API GetVersionExA
call anyway?)

It is NT 5.1, isn't it?

AFAIK, XP is NT 5.1 (major == 5, minor == 1).
