As far as I know, Win32API.so can not support API that uses a
callback procedure such as EnumWindows().  Ruby/DL will be the
better one for his problem.

Ruby/DL -- http://www.ruby-lang.org/en/raa-list.rhtml?id=629

require 'dl'

User32 = DL.dlopen("user32")
enum_windows = User32['EnumWindows', 'IPL']
post_message = User32['PostMessage', 'ILILL']
get_class_name = User32['GetClassName', 'ILpI']

name = "IEFrame"
buff = " " * 16
WM_CLOSE = 0x0010
TRUE = 1

enum_windows_proc = DL.callback('ILL') {|hwnd,lparam|
  r,rs = get_class_name.call(hwnd, buff, buff.size)
  if /^#{name}$/ =~ rs[1].to_s
    r,rs = post_message.call(hwnd, WM_CLOSE, 0, 0)
  end
  TRUE
}

r,rs = enum_windows.call(enum_windows_proc, 0)
