I did something like this a while back:

class File
  def self.mkfifo(name, mode=3D"0600", open_mode=3D"rw")
    if ! File.writeable? File.dirname(name)
      raise Errno::EACCES, "No such directory"
    end

    if File.exists? name and File.pipe? name # Leftover from before
      File.delete name
    end

    if ! File.exists? name
      system("mkfifo", "--mode=3D" + mode, name)
      @@created_fifos << name
    end

    return File.open(name, open_mode)
=20
--=20
