How to write to stdin of execved process?

问题

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?

回答1:

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.

Take a look at this link for a detailed example on how to use pipes: http://tldp.org/LDP/lpg/node11.html
