Bug #5897: RubyからWinAPIのCreateProcessを使ったときに引数を間違えるとバグがでる
https://bugs.ruby-lang.org/issues/5897

Author: 西行寺 うゆ
Status: Feedback
Priority: Normal
Assignee: Usaku NAKAMURA
Category: ext
Target version: 
ruby -v: ruby 1.9.3p0 (2011-10-30) [i386-mingw32]


require 'Win32API'

CreateProcess = Win32API.new('kernel32', 'CreateProcess', %w(ipiiiiiipp), 'i')

NULL = 0
FALSE = 0
lpCommandLine = ""

CreateProcess.call(
    NULL,         
    lpCommandLine,  
    NULL,         
    NULL,         
    FALSE,        
    FALSE,
    NULL,         
    NULL,        
    "",
    0
    )

引数は間違えないのが理想ですが
間違ったときには[BUG]じゃなくてエラーメッセージがいいんじゃないかなと
