Some Win32API calls don't work in JRuby
---------------------------------------
Key: JRUBY-4323
URL: http://jira.codehaus.org/browse/JRUBY-4323
Project: JRuby
Issue Type: Bug
Components: Windows
Affects Versions: JRuby 1.4
Reporter: Vladimir Sizikov
Fix For: JRuby 1.5
Take a look, MRI allows 0 as arguments in some message calls, while JRuby
doesn't:
{code}
require 'Win32API'
FormatMessageA = Win32API.new('kernel32.dll', 'FormatMessageA', 'LPLLPLP', 'L')
code = 234
msg = "\0" * 1024
# doesn't work in JRuby
len = FormatMessageA.call(0x1200, 0, code, 0, msg, 1024, 0)
# works in MRI and JRuby
# len = FormatMessageA.call(0x1200, nil, code, 0, msg, 1024, nil)
puts msg.chomp[0, len].tr("\r", '').chomp
{code}
MRI prints: More data is available.
JRuby prints:
winapi_test.rb:8: Invalid buffer/pointer parameter (ArgumentError)
