C++ (Cpp) Path::isEmpty Examples

Example #1

    std::vector<const char*> args;
    // args[0] should be the name of the executable
    args.push_back(gExePath.c_str());
    // Skip first argument to -run; it's a D source file.
    for (size_t i = 1, length = opts::runargs.size(); i < length; i++)
    {
        args.push_back(opts::runargs[i].c_str());

    // terminate args list
    args.push_back(NULL);

    // try to call linker!!!
