how to convert String in arduino library to std::string in c++

I have problem converting a String to std::string, to pass it to my function as the sample of my code is

String dataString = configFile.readString();
rawData = simplifyData("try to fetch data as string from dataString");

Since std::string has a constructor accepting a const char* as parameter you can copy your String by using this, e.g.:

rawData = simplifyData(std::string(dataString.c_str()));

Or, since this constructor is implict, you can simplify it in your function call, such as

rawData = simplifyData(dataString.c_str());
