Comparing pseudo handles?
I know we can check whether 2 handles are same by using
https://docs.microsoft.com/en-us/windows/win32/api/handleapi/nf-handleapi-compareobjecthandles
However this won't work for pseudo handles.
Is there any way to compare 2 pseudo handles for equality?
For example you 2 HWND's and need to compare if they are equal, that is both are same window.

Hi malibor
I hope this helps a little or not.
HWND window1
HWND window2
window1=CreateWindowEx ...
window2=CreateWindowEx ...
compare window1 with window2

from what I understand such comparison is not valid because system may reuse handle once one of the 2 windows is destroyed.
But otherwise comparison is valid as long as both windows live.

pseudo handles are local to process as opposed to real handles which are system wide.
After some researching I learned comparing pseudo handles is not reliably possible.
A workaround that works is to wrap the handle into C++ object, implement destruction events and compare objects instead.
