"""
A file-like object that operates on non-blocking files but
provides a synchronous, cooperative interface.
.. caution::
This object is most effective wrapping files that can be used appropriately
with :func:`select.select` such as sockets and pipes.
In general, on most platforms, operations on regular files
(e.g., ``open('/etc/hosts')``) are considered non-blocking
already, even though they can take some time to complete as
data is copied to the kernel and flushed to disk (this time
is relatively bounded compared to sockets or pipes, though).
A :func:`~os.read` or :func:`~os.write` call on such a file
will still effectively block for some small period of time.
Therefore, wrapping this class around a regular file is
unlikely to make IO gevent-friendly: reading or writing large
amounts of data could still block the event loop.
If you'll be working with regular files and doing IO in large
chunks, you may consider using
:class:`~gevent.fileobject.FileObjectThread` or
:func:`~gevent.os.tp_read` and :func:`~gevent.os.tp_write` to bypass this
concern.
.. note::
Random read/write (e.g., ``mode='rwb'``) is not supported.
For that, use :class:`io.BufferedRWPair` around two instance of this
class.
.. tip::
Although this object provides a :meth:`fileno` method and
so can itself be passed to :func:`fcntl.fcntl`, setting the
:data:`os.O_NONBLOCK` flag will have no effect; likewise, removing
that flag will cause this object to no longer be cooperative.
