    code to run (linux) programs WITH arguments

    I'd need a function or code to run linux programs with arguments from my C++ program.
    e.g.
    "Run> someapp 1 2 3 -a -b".
    Thanks for all answers!!

    The same way you always do. Linux is nothing special in this respect:

    int main( int argc, char *argv[] )

    Quzah.
    Hope is the first step on the road to disappointment.

    you got me wrong

    That's not what I wanted to know! ;-)
    My question wasn't good. I mean, I write a program like this:

    int main()
    {
    int x, y;
    cout<<"Program you want to run:";
    cin>>x;
    cout<<"Arguments:";
    cin>>y;

    <code to run x with y>
    }

    I hope you understand what I mean!!!

    Take a look at the "exec" functions. They will do what you want. Do a "man execlp" for help.
