現在開いている処理対象のファイルがARGFがcloseされていればtrueを返します。
...理対象のファイルがARGFがcloseされていればtrueを返します。
例:
# $ echo "foo" > foo

# $ ruby argf.rb foo bar
ARGF.filename # => "foo"
ARGF.close
# 複数のファイルを開いているので1度のARGF.closeではまた全てのファイル......を閉じていないのでfalseになる
ARGF.closed? # => false
ARGF.filename # => "bar"
ARGF.close
# 2つのファイルを開いていたので2度目のARGF.closeで全てのファイルを閉じたためtrueになる
ARGF.closed? # => true
