It's already defined. Just use QueryPerformanceCounter, (no
extern).
I'm a newby. Can you show me an example? In which module is it?
When you do the import, it include already the function ready to
use, it isn't like C#'s PInvoke system for example, where tou
need to add a function sginature/prototype with the dll where
it's defined.

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();
//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.

Just import core.sys.windows.windows and call the function like
so:
---
import core.sys.windows.windows;
void main() {
LARGE_INTEGER pc;
QueryPerformanceCounter();
}
---

I tried this. Returns errors, doesn't know what BOOL and
LARGE_INTEGER are.
import core.sys.windows.windows;
