There are certain OS-specific ways to get that data from somewhere. They neither require Perl nor are fulfilled by Perl. They can be used from Perl or from many other languages, but only on the specific OSes that support them. Why specifically do you need it, and wouldn't it be better if that didn't matter to your program in the first place?
