Get process id by name

Question

I would like to get the process identifier with his name under Linux.

Is there an easy way to do this?

I did not find anything in C ++ that could be easily used!

Answer 1

You can use the information in /proc .

Here is an example.

Answer 2

If it’s easy to use,

 char buf[512]; FILE *cmd_pipe = popen("pidof -s process_name", "r"); fgets(buf, 512, cmd_pipe); pid_t pid = strtoul(buf, NULL, 10); pclose( cmd_pipe ); 

- way.

Yes, this is ugly, I know. It is much better to go and read the pidof source code.
