[Interest] Converting std::string.c_str() code to use QString methods

I use toUtf8()... Though it wouldn't surprise me if Thiago scolds me for it :)

Note, If you are using a variatic function (printf), you need to use toUtf8().data()

toUtf() returns a QbyteArray which has a conversion operator to char *...

Subject: [Interest] Converting std::string.c_str() code to use QString methods

I have a large code base that we are migrating to more fully utilize Qt classes. Many places in the code have lines like the following:

std::string path("/path/to/foo.txt");
FILE* f = fopen(path.c_str(), "wb");

If the "path" variable is now declared as a QString which QString method would be me the equivalent as the "c_str()" of std::string?

Not sure if I should be using "toASCII()" or "data()" or "toUtf8()" or what exactly.

Google didn't really give me a definitive answer.

Many Thanks
