使用prctl PR_SET_NAME设置进程或线程的名称? [英] Using prctl PR_SET_NAME to set name for process or thread?

问题描述

我正在尝试使用prctl( PR_SET_NAME, "procname", 0, 0, 0)为进程设置名称，当我阅读有关PR_SET_NAME的Linux手册时，如果我理解正确的话，它似乎为线程设置了名称.

I am trying to use prctl( PR_SET_NAME, "procname", 0, 0, 0) to set name for a process, when I am reading the Linux Manual about the PR_SET_NAME, looks like it set the name for thread if I understand it correctly.

可以使用prctl设置进程名称吗?如何为进程设置名称?

Can prctl be used to set name for process? How to set name for process?

推荐答案

是的，您可以在第一个参数中使用PR_SET_NAME，并在第二个参数中使用名称来设置调用线程(或进程)的名称. prctl成功返回0.请记住，这取决于您在何处将此称为prctl.如果在进程内部调用它，它将更改该进程及其所有所属线程的名称.如果在特定线程内调用它，它将仅更改该线程的名称.

Yes, you may use PR_SET_NAME in the first argument and the name as the second argument to set the name of the calling thread(or process). prctl returns 0 on success. Remember, it depends where you call this prctl. If you call it inside your process, it will change the name of that process and all of its belonging threads. If you call it inside a specific thread, it will change only the name of that thread.

示例:

int s;
s = prctl(PR_SET_NAME,"myProcess\0",NULL,NULL,NULL); // name: myProcess

现在，如果您正在Linux中运行进程，请输入:

Now, if you are running your process in Linux, type:

top

或

ps

要查看附加到您的进程ID的名称.

To see the name attached to your process id.
