+Slice Objects
+-------------
+
+
+.. c:var:: PyTypeObject PySlice_Type
+
+   The type object for slice objects.  This is the same as :class:`slice` in the
+   Python layer.
+
+
+.. c:function:: int PySlice_Check(PyObject *ob)
+
+   Return true if *ob* is a slice object; *ob* must not be *NULL*.
+
+
+.. c:function:: PyObject* PySlice_New(PyObject *start, PyObject *stop, PyObject *step)
+
+   Return a new slice object with the given values.  The *start*, *stop*, and
+   *step* parameters are used as the values of the slice object attributes of
+   the same names.  Any of the values may be *NULL*, in which case the
+   ``None`` will be used for the corresponding attribute.  Return *NULL* if
+   the new object could not be allocated.
+
+
+.. c:function:: int PySlice_GetIndices(PyObject *slice, Py_ssize_t length, Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step)
+
+   Retrieve the start, stop and step indices from the slice object *slice*,
+   assuming a sequence of length *length*. Treats indices greater than
+   *length* as errors.
+
+   Returns ``0`` on success and ``-1`` on error with no exception set (unless one of
+   the indices was not :const:`None` and failed to be converted to an integer,
+   in which case ``-1`` is returned with an exception set).
+
+   You probably do not want to use this function.
+
+   .. versionchanged:: 3.2
+      The parameter type for the *slice* parameter was ``PySliceObject*``
+      before.
+
+
+.. c:function:: int PySlice_GetIndicesEx(PyObject *slice, Py_ssize_t length, Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step, Py_ssize_t *slicelength)
+
+   Usable replacement for :c:func:`PySlice_GetIndices`.  Retrieve the start,
+   stop, and step indices from the slice object *slice* assuming a sequence of
+   length *length*, and store the length of the slice in *slicelength*.  Out
+   of bounds indices are clipped in a manner consistent with the handling of
+   normal slices.
+
+   Returns ``0`` on success and ``-1`` on error with exception set.
+
+   .. versionchanged:: 3.2
+      The parameter type for the *slice* parameter was ``PySliceObject*``
+      before.
+
+
+Ellipsis Object
+---------------
+
+
+.. c:var:: PyObject *Py_Ellipsis
+
+   The Python ``Ellipsis`` object.  This object has no methods.  It needs to be
+   treated just like any other object with respect to reference counts.  Like
+   :c:data:`Py_None` it is a singleton object.
