-.. cfunction:: void PyString_InternInPlace(PyObject **string)
-
-   Intern the argument *\*string* in place.  The argument must be the address of a
-   pointer variable pointing to a Python string object.  If there is an existing
-   interned string that is the same as *\*string*, it sets *\*string* to it
-   (decrementing the reference count of the old string object and incrementing the
-   reference count of the interned string object), otherwise it leaves *\*string*
-   alone and interns it (incrementing its reference count).  (Clarification: even
-   though there is a lot of talk about reference counts, think of this function as
-   reference-count-neutral; you own the object after the call if and only if you
-   owned it before the call.)

-   with the same value.

-
-   Create an object by decoding *size* bytes of the encoded buffer *s* using the
-   codec registered for *encoding*.  *encoding* and *errors* have the same meaning
-   as the parameters of the same name in the :func:`unicode` built-in function.
-   The codec to be used is looked up using the Python codec registry.  Return
-   *NULL* if an exception was raised by the codec.

-
-.. cfunction:: PyObject* PyString_AsDecodedObject(PyObject *str, const char *encoding, const char *errors)
-
-   Decode a string object by passing it to the codec registered for *encoding* and
-   return the result as Python object. *encoding* and *errors* have the same
-   meaning as the parameters of the same name in the string :meth:`encode` method.
-   The codec to be used is looked up using the Python codec registry. Return *NULL*
-   if an exception was raised by the codec.
-
-
-.. cfunction:: PyObject* PyString_AsEncodedObject(PyObject *str, const char *encoding, const char *errors)
-
-   Encode a string object using the codec registered for *encoding* and return the
-   result as Python object. *encoding* and *errors* have the same meaning as the
-   parameters of the same name in the string :meth:`encode` method. The codec to be
-   used is looked up using the Python codec registry. Return *NULL* if an exception
-   was raised by the codec.
