问题描述
如何从C ++获取 PyObject
的引用计数?
How to get reference count of a PyObject
from C++?
有一些函数 Py_INCREF
和 Py_DECREF
减少它,但我还没有找到返回对象的引用计数的任何函数。
There are functions Py_INCREF
and Py_DECREF
which increase/decrease it, but I haven't found any function which return object's reference count.
我需要它为调试目的。
推荐答案
每个对象的引用计数都存储在 PyObject
https://hg.python.org/cpython/file/37d896c3604a/Include/object.h#l107> ob_refcnt
。
The reference count of each and every object is stored in the PyObject
itself, in a variable called ob_refcnt
. You can directly access that.
typedef struct _object {
_PyObject_HEAD_EXTRA
Py_ssize_t ob_refcnt; # Reference count
struct _typeobject *ob_type;
} PyObject;
或者,您可以使用。
Alternatively, you can use the Py_REFCNT
Macro.
