Is there a way to obtain a FILE* from an a iostream derived class? Particularly from an fstream?

Answer 1

No, at least not in a portable way.

GCC's libstdc++ has a class called stdio_filebuf that you can use with a stream, and it does allow you to directly get the associated FILE*, but, stdio_filebuf is not a basic_filebuf, and cannot be used with basic_fstream.
