std string class and printf


This doesn't work:

Code:
#include <string>
unsing namespace std;

class MyStringType : public string
{
    public:
        void printf(char *, ...);
};

void MyStringType::printf(char *FormatString, ...)
{
    //etc ...
}

int main(int argc, char **argv)
{
    MyStringType;
    char *TestStr="Hello World!";
    MyStringType.printf("%s", TestStr);
}
This doesn't work. How can I make a wrapper for the standard C++ string class that adds a printf function?

Code:
#include <stdio.h>
...
       printf("%s", myString.c_str());
close enough?

I thought it was bad to do that.

Well, it's not very c++ish and it will truncate if there's a \0 in the string. That's all that's wrong with it afaik
