How to confirm whether some process is opened by process name?

angelyouyou

My application opened one pcap file with wireshark with specify name.
I want to know how to confirm whether the process is opened by process name.
Process name examples:
pcap_file_2021-07-01-20-46-36.pcap
pcap_file_2021-07-01-20-20-01.pcap
....

You will need to use native calls for whatever your OS is to achieve this.

I saved the QProcess pointer of the opened wireshark process, can I use it to judge whether the process is opened?
I open the wireshark process by StarDetached API, but
I can't confirm the process is running.

If QProcess::startDetatched() returns true, then the process has started.
It also gives you the process ID (pid) if that is of use.

You need to more specific about what exactly you are looking for/how these processes are started.

If you are only interested in processes which you launched via Qt's QProcess you might check via PID instead of name. Or you can look at QProcess::program() for each process. However, the examples you show do not look like the names of launchable processes, but who knows because you don't say what the program name(s) is/are when you launch them.

I read your requirement as "Use OS-specific call to list the names of all running processes, and compare names against what I am looking for". Otherwise I don't know why you are interested in process names. But perhaps you do mean only processes your Qt app has launched, in which case I have indicated PID or maybe QProcess::name() is what you are interested in.
