[llvm-dev] How to pass arbitrary arguments to runFunctionAsMain?

I'm trying to call the function main passing arbitrary parameters. My code
is something like:

Please note that MyInterpreter extends Interpreter

    StringRef filename = argv[1];
    std::unique_ptr<Module> m(parseIRFile(filename, error, context));
    MyInterpreter * v = new MyInterpreter(std::move(m));
    errs() << "Done\n";
    Function *main = v->FindFunctionNamed("main");

    errs() << " Function " << main->getName().str() << "\n";

    std::vector<std::string> parameters;

    parameters.insert(parameters.begin(), "argv");

    const char* const* envp;
    for (int i=1; i<argc;i++)

    v->runFunctionAsMain(main, parameters, envp);

Is it correct or should I construct parameters in another way?

Thanks a lot
