 Python's built-in file objects are implemented entirely on the :ctype:`FILE\*`
 support from the C standard library.  This is an implementation detail and may

-.. ctype:: PyFileObject
-
-   This subtype of :ctype:`PyObject` represents a Python file object.

-.. cvar:: PyTypeObject PyFile_Type
-
-   .. index:: single: FileType (in module types)
-
-   This instance of :ctype:`PyTypeObject` represents the Python file type.  This is
-   exposed to Python programs as ``file`` and ``types.FileType``.

-.. cfunction:: int PyFile_Check(PyObject *p)

-.. cfunction:: int PyFile_SetEncoding(PyFileObject *p, const char *enc)
-
-   Set the file's encoding for Unicode output to *enc*. Return 1 on success and 0

-
-   This function exists for internal use by the interpreter.  Set the

-   *p* does not have to be a file object for this function to work properly; any
-   object is supported (thought its only interesting if the :attr:`softspace`
-   attribute can be set).  This function clears any errors, and will return ``0``
-   as the previous value if the attribute either does not exist or if there were
-   errors in retrieving it.  There is no way to detect errors from this function,
-   but doing so should not be needed.
