Python ctypes: How do I flush output from stderr?
提问by Ryan
I've written some function callbacks using python's ctypes to access functions in a DLL. The code used to build that DLL has some debugging print statements in it using fprintf to stderr. However, when I run my python code, I don't see that output to stderr consistently. Only rarely I will see it flush the output from stderr to the console that I'm using. I've tried running it with "python -u foo.py", but that doesn't help either. Any suggestions?
我已经使用 python 的 ctypes 编写了一些函数回调来访问 DLL 中的函数。用于构建该 DLL 的代码中有一些使用 fprintf 到 stderr 的调试打印语句。但是，当我运行我的 python 代码时，我没有看到一致的输出到 stderr。我很少会看到它将 stderr 的输出刷新到我正在使用的控制台。我试过用“python -u foo.py”运行它，但这也无济于事。有什么建议？

It's all the same stderr.
都是一样的标准错误。
sys.stderr.flush()
