  The type object corresponding to coroutine objects.

int `PyCoro_CheckExact`(PyObject *ob)

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

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

  Create and return a new coroutine 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`.
