Hi all,

Ruby 1.8.4

I'm working on a pure Ruby Process.create method.  What I have below 
seems to work, except that if I attempt to pass an environment string, 
it causes the app to die instantly.  What am I doing wrong?

require 'Win32API'

params = 'LPLLLLLLPP'
CreateProcess = Win32API.new('kernel32','CreateProcess', params, 'I')

def create(hash={})
    env = 0
    if hash['environment']
       env = hash['environment'].split(File::PATH_SEPARATOR) << nil
       env = env.pack('p*').unpack('L').first
    end

    startinfo = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]
    startinfo = startinfo.pack('LLLLLLLLLLLLSSLLLL')
    procinfo  = [0,0,0,0].pack('LLLL')

    CreateProcess.call(
       0, "notepad", 0, 0, 0, 0, env, 0, startinfo, procinfo
    )

    return procinfo[8,4].unpack('L').first # pid
end

p create() # ok
p create('environment'=>"PATH=C:\\;LIB=C:\\lib" # boom!

What have I goofed up here?

Thanks,

Dan
