It was added a private function (``_Py``) prefix and it's not part of the limited C API.\n\nThis function is widely used in the Python code base which means that it's useful. Casting PyLong_AsLong() to ``int`` and then checking for overflow is error prone, it requires to raise the right exception.\n\nUsing a private function is a bad practive: I removed many private functions from Python 3.13 C API, see issue #106320.\n\nI propose to add  PyLong_AsInt() to the limited C API, add documentation and tests.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-108445\n* gh-108458\n* gh-108459\n* gh-108461\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/vstinner","@type":"Person","name":"vstinner"},"datePublished":"2023-08-24T18:05:56.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/108444/cpython/issues/108444"}
