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*.

int PyGen_CheckExact(PyObject *ob)

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

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*.
