API Questions
#1
Since I've started diving into API calls I figured a dedicated thread for API related questions would be better.

Here is my first question.

In the Wiki here: https://qb64phoenix.com/qb64wiki/index.p...ndow_Focus

It's shown how to determine the foreground window (the one in focus).

The Microsoft docs for GetForegroundWindow are located here: https://learn.microsoft.com/en-us/window...oundwindow

I noticed in the Wiki example that GetForegroundWindow is declared as an _OFFSET (%&). How was this determined? Looking at the Microsoft docs there is no indication of the type of variable returned. With other window handle (hWnd) related functions I've noticed a variable type of LONG is used. Why was _OFFSET needed here instead of LONG?

This has me confused. Any clarification would be greatly appreciated.
Software and cathedrals are much the same — first we build them, then we pray.
