问题描述

I'm trying to execve a process that reads from stdin. I want to prepare stdin with some data so it can execute successfully. How can I do that?

推荐答案

您将需要将execve调用派生到子进程中，然后创建从父进程到子级stdin的管道.

You will need to fork the execve call into a child process and then create a pipe from the parent process to the child's stdin.

请查看此链接，以获取有关如何使用管道的详细示例: http://tldp.org/LDP/lpg/node11.html
