+Slice Objects
+-------------
+
+
+.. cvar:: PyTypeObject PySlice_Type
+
+ .. index:: single: SliceType (in module types)
+
+ The type object for slice objects. This is the same as ``slice`` and
+ ``types.SliceType``.
+
+
+.. cfunction:: int PySlice_Check(PyObject *ob)
+
+ Return true if *ob* is a slice object; *ob* must not be *NULL*.
+
+
+.. cfunction:: 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.
+
+
+.. cfunction:: int PySlice_GetIndices(PySliceObject *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. If you want to use slice objects
+ in versions of Python prior to 2.3, you would probably do well to incorporate
+ the source of :cfunc:`PySlice_GetIndicesEx`, suitably renamed, in the source of
+ your extension.
+
+
+.. cfunction:: int PySlice_GetIndicesEx(PySliceObject *slice, Py_ssize_t length, Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step, Py_ssize_t *slicelength)
+
+ Usable replacement for :cfunc:`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.
+
+ .. versionadded:: 2.3
