C and C++ are two different languages. Windows SDK interface is defined 
in C, not C++.

MessageBoxW is documented at 
"https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-messagebox" 
  - it does not mention any timeout.

I have written some code for a "Windows popup with timeout" in C++, but 
I doubt it will help you. It displays the message box in a separate 
thread, while the main thread waits for it on a condition variable with 
a timeout.

I guess you would get better responses in forums where Perl or Windows 
are on topic.
