Generator objects are what Python uses to implement generator iterators. They are normally created by iterating over a function that yields values, rather than explicitly calling :c:func:`PyGen_New` or :c:func:`PyGen_NewWithQualName`.

.. c:type:: PyGenObject

   The C structure used for generator objects.

.. c:var:: PyTypeObject PyGen_Type

   The type object corresponding to generator objects.

.. c:function:: int PyGen_Check(PyObject *ob)

   Return true if *ob* is a generator object; *ob* must not be *NULL*.

.. c:function:: int PyGen_CheckExact(PyObject *ob)

   Return true if *ob*'s type is *PyGen_Type*; *ob* must not be *NULL*.

.. c:function:: PyObject* PyGen_New(PyFrameObject *frame)

   Create and return a new generator object based on the *frame* object.
   A reference to *frame* is stolen by this function. The argument must not be
   *NULL*.

.. c:function:: PyObject* PyGen_NewWithQualName(PyFrameObject *frame, PyObject *name, PyObject *qualname)

   Create and return a new generator object based on the *frame* object,
   with ``__name__`` and ``__qualname__`` set to *name* and *qualname*.
   A reference to *frame* is stolen by this function.  The *frame* argument
   must not be *NULL*.
