"Descriptors" are objects that describe some attribute of an object. They are found in the dictionary of type objects.
.. c:var:: PyTypeObject PyProperty_Type
The type object for the built-in descriptor types.
.. c:function:: PyObject* PyDescr_NewGetSet(PyTypeObject *type, struct PyGetSetDef *getset)
.. c:function:: PyObject* PyDescr_NewMember(PyTypeObject *type, struct PyMemberDef *meth)
.. c:function:: PyObject* PyDescr_NewMethod(PyTypeObject *type, struct PyMethodDef *meth)
.. c:function:: PyObject* PyDescr_NewWrapper(PyTypeObject *type, struct wrapperbase *wrapper, void *wrapped)
.. c:function:: PyObject* PyDescr_NewClassMethod(PyTypeObject *type, PyMethodDef *method)
.. c:function:: int PyDescr_IsData(PyObject *descr)
Return non-zero if the descriptor objects *descr* describes a data attribute, or
``0`` if it describes a method. *descr* must be a descriptor object; there is
no error checking.
