    FILE* from fstream

    I have searched for the answer, but couldn't find anything. I need to use fstat to know a file size. But my file is ifstream.I've tryied rdbuf()->fd(), but gcc says that fd() does not exists. Thanks any help!

    Code:
    int GetFileSize(std::ifstream& File)
    {
      File.seekg(0, std::ios::end);
      return static_cast<int>(File.tellg());
    }

    Another option is to use stat() to get the file size. It takes a filename versus a FILE *.
