Write a file in a specific path in C++

Question

I have this code that writes successfully a file:

    ofstream outfile (path);
    outfile.write(buffer,size);
    outfile.flush();
    outfile.close();

It's not too clear what you're asking; if I understand correctly, you're given a filename, and you want to create the file in a specific directory. If that's the case, all that's necessary is to specify the complet path to the constructor of ofstream. You can use string concatenation to build up this path, but I'd strongly recommend boost::filesystem::path. It has all of the functions to do this portably, and a lot more; otherwise, you'll not be portable (without a lot of effort), and even simple operations on the filename will require considerable thought.
