Focus on already running process by giving ID or name?

Is this possible to be done with C++ ?
I am working on Qt Creator by I didn't find any working setFocus function or something. Can you help me a bit?
Thank you.
The program actually checks if there is a process of this program already running and if there is it exits.
I want to make it focus on the already running program but I've failed... :/

You have to find out how debugging works in your system. In UNIX, this is usually system dependent. There is a set of functions, an API, designed to connect to and control other processes. This API is meant for debugging primarily.

You can bypass all this by using a debugger, like gdb. This lets you connect to and control an already running process. If you want to see how to do it, get a copy of gdb source for your system.
