我可以注册SIGTERM，但是如何处理SIGKILL信号?

推荐答案

您不能，至少不是因为该进程被杀死.

You cannot, at least not for the process being killed.

您可以 做的是安排父进程监视子进程的死亡，并采取相应的措施.任何体面的过程监督系统(例如 daemontools )都内置有这样的工具.

What you can do is arrange for the parent process to watch for the child process's death, and act accordingly. Any decent process supervision system, such as daemontools, has such a facility built in.
