# Descriptor Objects

“Descriptors” are objects that describe some attribute of an object. They are found in the dictionary of type objects.

PyTypeObject PyProperty_Type
  Part of the Stable ABI.

  The type object for the built-in descriptor types.

PyObject *PyDescr_NewGetSet(PyTypeObject *type, struct PyGetSetDef *getset)
  Return value: New reference. Part of the Stable ABI.

PyObject *PyDescr_NewMember(PyTypeObject *type, struct PyMemberDef *meth)
  Return value: New reference. Part of the Stable ABI.

PyObject *PyDescr_NewMethod(PyTypeObject *type, struct PyMethodDef *meth)
  Return value: New reference. Part of the Stable ABI.

PyObject *PyDescr_NewWrapper(PyTypeObject *type, struct wrapperbase *wrapper, void *wrapped)
  Return value: New reference.

PyObject *PyDescr_NewClassMethod(PyTypeObject *type, PyMethodDef *method)
  Return value: New reference. Part of the Stable ABI.

int PyDescr_IsData(PyObject *descr)

  Return non-zero if the descriptor object descr describes a data attribute, or `0` if it describes a method. descr must be a descriptor object; there is no error checking.

PyObject *PyWrapper_New(PyObject*, PyObject*)
  Return value: New reference. Part of the Stable ABI.

## Built-in descriptors

PyTypeObject PySuper_Type
  Part of the Stable ABI.

  The type object for super objects. This is the same object as `super` in the Python layer.

PyTypeObject PyClassMethod_Type

  The type of class method objects. This is the same object as `classmethod` in the Python layer.

PyObject *PyClassMethod_New(PyObject *callable)

  Create a new `classmethod` object wrapping callable. callable must be a callable object and must not be `NULL`.

  On success, this function returns a strong reference to a new class method descriptor. On failure, this function returns `NULL` with an exception set.

PyTypeObject PyStaticMethod_Type

  The type of static method objects. This is the same object as `staticmethod` in the Python layer.

PyObject *PyStaticMethod_New(PyObject *callable)

  Create a new `staticmethod` object wrapping callable. callable must be a callable object and must not be `NULL`.

  On success, this function returns a strong reference to a new static method descriptor. On failure, this function returns `NULL` with an exception set.
