# Generator Objects

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 `PyGen_New()` or `PyGen_NewWithQualName()`.

`PyGenObject`

  The C structure used for generator objects.

PyTypeObject `PyGen_Type`

  The type object corresponding to generator objects.

int `PyGen_Check`(PyObject *ob)

  Return true if ob is a generator object; ob must not be `NULL`. This function always succeeds.

int `PyGen_CheckExact`(PyObject *ob)

  Return true if ob’s type is `PyGen_Type`; ob must not be `NULL`. This function always succeeds.

PyObject* `PyGen_New`(PyFrameObject *frame)
  Return value: New reference.

  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`.

PyObject* `PyGen_NewWithQualName`(PyFrameObject *frame, PyObject *name, PyObject *qualname)
  Return value: New reference.

  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`.
