# 协程对象

3.5 版新加入.

协程对象是使用 `async` 关键字声明的函数返回的。

`PyCoroObject`

  用于协程对象的C结构体。

PyTypeObject `PyCoro_Type`

  与协程对象对应的类型对​​象。

int `PyCoro_CheckExact`( PyObject *ob)

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

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.
