为什么OSX Activity Monitor不显示我启动的进程？
[英]Why doesn't OSX Activity Monitor show the processes I started?
问题描述
I'm using fork and execv to start child processes. 
我正在使用fork和execv启动子进程。 If I run htop then I can find those processes. 如果运行htop，则可以找到那些进程。 However, OSX Activity Monitor doesn't show them, even if I have it set to show all processes. 但是，即使我将其设置为显示所有进程，OSX Activity Monitor也不会显示它们。 Why is that? 这是为什么？
The S column in htop show Z for all of my processes. htop中的S列显示我所有过程的Z。 What does that mean? 这意味着什么？ Could that have something to do with it? 可能与这有关吗？

The Z in htop means the process is a "zombie". htop中的Z表示该过程是“僵尸”。 This means that the process has completed running and wants to die, but the parent process has not yet called wait() to obtain the child process exit code. 这意味着该进程已完成运行并希望终止，但是父进程尚未调用wait()来获取子进程退出代码。
It's possible that the OS X Activity Monitor does not show zombie processes. OS X活动监视器可能不显示僵尸进程。
