Then ask in a Windows programming newsgroup (assuming you can't find
the answer in your system's documentation).
comp.os.ms-windows.program mer.win32 is likely to be a good place to ask.

No, the code at that URL is Windows-specific (see the "#include <windows.h>"
in the source code).

I don't believe it's possible to implement a high-resolution timer
that's independent of the hardware and operating system. It may be
possible to implement one that's fairly widely portable, using a nest
of #ifdefs, but some systems may not even provide a way to get a time
to microsecond resolution.
