如何在python中将文件描述符从父对象传递给子对象? [英] How to pass file descriptors from parent to child in python?

问题描述

我正在使用多处理模块，并使用池来启动多个工作程序.但是在父进程中打开的文件描述符在工作进程中关闭.我要他们打开..！有什么方法可以传递要在父母和孩子之间共享的文件描述符?

I am using multiprocessing module, and using pools to start multiple workers. But the file descriptors which are opened at the parent process are closed in the worker processes. I want them to be open..! Is there any way to pass file descriptors to be shared across parent and children?

推荐答案

我不知道一种在进程之间共享文件描述符的方法. 如果存在，则很可能是特定于操作系统的.

There isn't a way that I know of to share file descriptors between processes. If a way exists, it is most likely OS specific.

我的猜测是您需要在另一个级别上共享数据.

My guess is that you need to share data on another level.
