It will be defined to be the best available implementation. All the parameters are as for :func:`io.open`. :param fobj: Usually a file descriptor of a socket. Can also be another object with a ``fileno()`` method, or an object that can be passed to ``io.open()`` (e.g., a file system path). If the object is not a socket, the results will vary based on the platform and the type of object being opened. All supported versions of Python allow :class:`os.PathLike` objects. .. versionchanged:: 1.5 Accept str and ``PathLike`` objects for *fobj* on all versions of Python. .. versionchanged:: 1.5 Add *encoding*, *errors* and *newline* arguments. .. versionchanged:: 1.5 Accept *closefd* and *buffering* instead of *close* and *bufsize* arguments. The latter remain for backwards compatibility. There are two main implementations of ``FileObject``. On all systems, there is :class:`FileObjectThread` which uses the built-in native threadpool to avoid blocking the entire interpreter. On UNIX systems (those that support the :mod:`fcntl` module), there is also :class:`FileObjectPosix` which uses native non-blocking semantics. A third class, :class:`FileObjectBlock`, is simply a wrapper that executes everything synchronously (and so is not gevent-compatible). It is provided for testing and debugging purposes. All classes have the same signature; some may accept extra keyword arguments. Configuration ============= You may change the default value for ``FileObject`` using the ``GEVENT_FILE`` environment variable. Set it to ``posix``, ``thread``, or ``block`` to choose from :class:`FileObjectPosix`, :class:`FileObjectThread` and :class:`FileObjectBlock`, respectively. You may also set it to the fully qualified class name of another object that implements the file interface to use one of your own objects. .. note:: The environment variable must be set at the time this module is first imported.
