# PyTypeObject PySlice_Type
#
# The type object for slice objects. This is the same as slice and types.SliceType
bint PySlice_Check(object ob)
#
# Return true if ob is a slice object; ob must not be NULL.
slice PySlice_New(object start, object stop, object 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.
int PySlice_GetIndices(object slice, Py_ssize_t length,
Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step) except? -1
#
# 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 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.
#
# Changed in version 3.2: The parameter type for the slice parameter was
# PySliceObject* before.
int PySlice_GetIndicesEx(object slice, Py_ssize_t length,
Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step,
Py_ssize_t *slicelength) except -1
#
# Usable replacement for 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.
#
# Changed in version 3.2: The parameter type for the slice parameter was
# PySliceObject* before.
int PySlice_Unpack(object slice, Py_ssize_t *start, Py_ssize_t *stop,
Py_ssize_t *step) except -1
# Extract the start, stop and step data members from a slice object as C
# integers. Silently reduce values larger than PY_SSIZE_T_MAX to
# PY_SSIZE_T_MAX, silently boost the start and stop values less than
# PY_SSIZE_T_MIN to PY_SSIZE_T_MIN, and silently boost the step values
# less than -PY_SSIZE_T_MAX to -PY_SSIZE_T_MAX.
# Return -1 on error, 0 on success.
# New in version 3.6.1.
Py_ssize_t PySlice_AdjustIndices(Py_ssize_t length, Py_ssize_t *start,
Py_ssize_t *stop, Py_ssize_t step)
# Adjust start/end slice indices assuming a sequence of the specified
# length. Out of bounds indices are clipped in a manner consistent with
# the handling of normal slices.
# Return the length of the slice. Always successful. Doesnt call Python
# code.
# New in version 3.6.1.
