    Ok, this seems elementary to me, but I can't for the life of me figure it out.

    I need to launch an app from my c++ app. But I need to know the PID. Am I able to find this out from system() or popen()?

    If I remember right, when you fork a process, the pid return value for the parent process is actual value of the child pid process, is that a way I could tackle this?

    Are you forking the process you want to open? If so, then yes, you can keep track when you fork.

    I am not using a fork() call specifically. Currently I am just using system() which in itself uses fork().

    Wow, that's kind of a personal question. Isn't there a Hot Chat forum on MacRumors?
