Question

我想在eclipse上运行一个c程序，通过JAVA ProcessBuilder，现在我想在某个地方向程序发送终止信号，该程序应该捕获该信号并执行所需的任务然后终止。现在我知道如何处理信号，但我如何从ProcessBuilder发送信号到我的程序。任何帮助将不胜感激！

请参阅此问题：How to send SIGINT signal from Java to an external process?

Can you send `kill -SIGINT <pid>` to the process (given that you know the process ID):

    Runtime.getRuntime().exec("kill -SIGINT 12345");

Of course, that would make for a platform-dependent solution... Potentially, you'll be able to use this tool, although it is in "sandbox mode". But it might give you an idea:
