May I ask what you intend to accomplish? A frequent use case for
serializing memory data is to write it to the local filesystem.
Presumably your ifstream represents a file that already exists on the
filesystem. Maybe you want to record the file's name? Perhaps you want
to record the current offset within that file? If so, I would
serialize those things specifically.

That's what i was thinking about.

I Have a file in the filesystem that i am reading and I would like to record the position I stop reading before I record the object that reads the file, so when I de-serialize that object I could use it and continue reading the same file in the recorded position.

How Do you think i can deal with this situation ?

Thank you
