Question

I was wondering how I could get the file name string from an archive, inside the serialize function or any other function that has the template<class archive> syntax.

Thanks! =)

There is no portable way of doing what you ask. The archive concept does not require using a file, nor does it even require using a C++ iostream-derived class. All of the libraries archive types use an iostream, but even those don’t have to be file streams.

You could create your own archive type of course. One specifically for files. Possibly derived from an existing one, passing arguments to the base class. It would have an extra function to get the name of the file that was used to create it.
