Thought I'd post this as an FYI.
I was investigating the magnification win32 API examples and eventually came across this link Magnification API Overview The first thing that jumped out was this note; "The Magnification API is not supported under WOW64; that is, a 32-bit magnifier application will not run correctly on 64-bit Windows." So started searching for alternatives. I did some more searching and came across Gary's thread Win10 Magnifier Alternative -July 2022 while I have played with Patrice's FFcapture in the past, post #3 by Hutch mentioned a 32bit MS Utility "zoomin.exe" but no source code go fish for yourself. So I went deep C fishing, I got to this site ZoomIt -Sysinternals and they have both 32 & 64bit binaries, the github link took me to the source code and I was surprised by all the other utilities available as well, here it is Microsoft PowerToys I'm still reading through it all to find the zoomin source code.
