I am relative new to C++ regarding it's functions and libraries. I need to

Have you actually tried and failed, or is that only your speculation?

If you get a "possible loss of data" warning when feeding seekg() with an
64 bit integer - what would you expect?

I expect not to use seekg then. Or switch to a better implementation of
the library.

AFAIK, even standard C Library functions like fread and fseek should
work with large files. And since C++ I/O streams are relatively thin
wrappers around C streams, those are expected to work just as well.
Write a program, see if you get it to work, if not, post your code and
explain the situation.

It may work for files, but can I work with them on memory streams?

I don't know what those are, sorry.
