I have a program written in C, which opens another program using popen. I 'd like to get the pid of that program or some kind of handler for it, so as to kill it after a certain time limit, or if it exceeds some ram, and stdout limits. I think this must be done with ptrace, which needs the PID, which I don't know how to obtain.

推荐答案

只写你自己的实现的popen 的返回的PID。它的丑陋远远小于围绕现有的popen 一些疯狂的两轮牛车。你可以找到源头code到的popen 实现全网。 这里有一个。

Just write your own implementation of popen that returns the PID. It's much less ugly than some crazy hackery around the existing popen. You can find source code to popen implementations all over the net. Here's one.
