# 实例方法对象

An instance method is a wrapper for a `PyCFunction` and the new way to bind a `PyCFunction` to a class object. It replaces the former call `PyMethod_New(func, NULL, class)`.

PyTypeObject `PyInstanceMethod_Type`

  This instance of `PyTypeObject` represents the Python instance method type. It is not exposed to Python programs.

int `PyInstanceMethod_Check`(PyObject *o)

  Return true if o is an instance method object (has type `PyInstanceMethod_Type`). The parameter must not be `NULL`.

PyObject* `PyInstanceMethod_New`(PyObject *func)
  Return value: New reference.

  Return a new instance method object, with func being any callable object func is the function that will be called when the instance method is called.

PyObject* `PyInstanceMethod_Function`(PyObject *im)
  Return value: Borrowed reference.

  Return the function object associated with the instance method im.

PyObject* `PyInstanceMethod_GET_FUNCTION`(PyObject *im)
  Return value: Borrowed reference.

  Macro version of `PyInstanceMethod_Function()` which avoids error checking.

# 方法对象

Methods are bound function objects. Methods are always bound to an instance of a user-defined class. Unbound methods (methods bound to a class object) are no longer available.

PyTypeObject `PyMethod_Type`

  This instance of `PyTypeObject` represents the Python method type. This is exposed to Python programs as `types.MethodType`.

int `PyMethod_Check`(PyObject *o)

  Return true if o is a method object (has type `PyMethod_Type`). The parameter must not be `NULL`.

PyObject* `PyMethod_New`(PyObject *func, PyObject *self)
  Return value: New reference.

  Return a new method object, with func being any callable object and self the instance the method should be bound. func is the function that will be called when the method is called. self must not be `NULL`.

PyObject* `PyMethod_Function`(PyObject *meth)
  Return value: Borrowed reference.

  Return the function object associated with the method meth.

PyObject* `PyMethod_GET_FUNCTION`(PyObject *meth)
  Return value: Borrowed reference.

  Macro version of `PyMethod_Function()` which avoids error checking.

PyObject* `PyMethod_Self`(PyObject *meth)
  Return value: Borrowed reference.

  Return the instance associated with the method meth.

PyObject* `PyMethod_GET_SELF`(PyObject *meth)
  Return value: Borrowed reference.

  Macro version of `PyMethod_Self()` which avoids error checking.

int `PyMethod_ClearFreeList`()

  清空释放列表。 返回所释放的条目数。
