FO_DELETE = 3

FOF_ALLOWUNDO      =  64

SHFileOperation = Win32API.new('shell32', 'SHFileOperation', 'P', 'I')

def recycle(fname, confirm = FOF_NOCONFIRMATION)
  fnp = fname.to_s << "\0\0"
  confirm = 0 unless confirm == FOF_NOCONFIRMATION
  shfos = [
            0, FO_DELETE, fnp, 0, FOF_ALLOWUNDO | confirm, 0, 0, 0
          ].pack('LLpLLLLL')
  SHFileOperation.call(shfos)==0 ? true : false
end

  fo.puts 'to_be_rescued'
