win32utils devel - Feb 2011 - WSAStartup failure

Hi,

I added the Windows::WSA module to windows-pr recently (it''s in the
latest
git repo). However, I can''t seem to make WSAStartup work. I tried the
following bit of code, only to get "The Windows Sockets version requested
is
not supported" on my Vista box.

Is it really not supported on Vista? The docs say Win2k or later. Or is
there another issue?

require ''windows/wsa''
require ''windows/error''
require ''windows/system_info''

include Windows::WSA
include Windows::Error
include Windows::SystemInfo

begin
  version = MAKEWORD(2,2)
  buffer = 0.chr * 532
  err = WSAStartup(version, buffer)

  if err != 0
    puts "Oops: " + get_last_error(err)
  end
ensure
  WSACleanup()
end

The current definition of MAKEWORD and MAKELONG is wroing.

Here is fixed version of MAKEWORD and MAKELONG.

def MAKEWORD(a, b)
      ((a & 0xff) | ((b & 0xff) << 8))
end
def MAKELONG(a, b)
      ((a & 0xffff) | ((b & 0xffff) << 16))
end

Ack, thanks. I''m pretty sure I copy/pasted this, so I''m
assuming
there''s a precedence issue. Ruby is *usually* the same as C, so
I''m
somewhat surprised here.
