如何在python中将文件描述符从父级传递给子级? [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人员.但是在父进程中打开的文件描述符在工作进程中是关闭的.我希望他们开放..！有没有办法传递文件描述符以在父子之间共享?

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

据我所知，没有一种方法可以在进程之间共享文件描述符.如果存在方法，它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.
