Actually, there isn't much you can do.
- Modify the receiving function to take a 64-bit parameter. Don't worry
about portability since you are anyway using a Win32-specific function to
retrieve the value.
- Modify the receiving function to take a scaled (kB maybe) value.
- Modify function to take two params. High + low. Not a nice solution.
There really isn't any other way since real partitions normally are larger
than 4GB, i.e. need more than 32-bit to represent size.
