Just import core.sys.windows.windows and call the function like 
so:

---
import core.sys.windows.windows;

void main() {
   LARGE_INTEGER pc;
   QueryPerformanceCounter(&pc);
}
---

I see. What Editor/IDE are you using btw?

If you use Visual Studio 2019 with the VisualD extension or 
Visual Studio Code with the D Programming Language (code-d) 
extension you can get some nice help with these kinds of things.

To the question, try this:

import std.stdio;

import core.sys.windows.winbase;
import core.sys.windows.windef;
import core.sys.windows.windows;

void main()
{
     LARGE_INTEGER li;

     BOOL b = QueryPerformanceCounter(&li);

     //Don't know what you're after. Defined in winnt
     writeln(li.QuadPart);

     readln();
}

I use online DMD. I'll try VS 2019 with the VisualD.

You don't need VisualD for this. Just plain old dmd in a text 
editor will do.

When you do the import, it include already the function ready to 

need to add a function sginature/prototype with the dll where 
it's defined.
