How to kill process in c++, knowing only part of its name

Question

Some time ago I needed to write c++ code to kill some process. In my main program I run large CAE-system package with system(\"...\") with different filename strings on inpu

Answer 1

This should just work assuming filename isn't too much exotic or contains a regular expression pattern:

string s="pkill -9 -f "+filename";
system(s.c_str());

As a side note, -9 is a last resort signal, not something you should start with. I would thus recommend the less brutal:

string s="pkill -f "+filename"+";sleep 2; pkill -9 -f "+filename;
system(s.c_str());
