There is no universal API for this.  It depends on which OS you're
using.  For that, you need to consult your OS's documentation. Most
likely there will be some kind of C API or system library that could
give you this information.

D can't possibly provide a universal API for something like this because
it varies too widely -- some platforms do not have any meaningful
notion of "battery level", whereas other systems may well have multiple
"battery levels" and it would be ambiguous which one is meant.  If you
want to do systems programming you have to know the system you're
programming, and be prepared to call OS APIs yourself.
