Re: [PATCH] do not call GetHandleInformation() in Winstore apps

[Bruno Haible]

Hi,

This thread is obviously related to what we discussed three years ago:
https://lists.gnu.org/archive/html/bug-gnulib/2020-05/msg00376.html

At that time, we discussed the function GetFileInformationByHandle,
and it is implemented in mingw's winstorecompat library:
https://github.com/mirror/mingw-w64/blob/master/mingw-w64-libraries/winstorecompat/src/GetFileInformationByHandle.c

Ah, you mean the marker "[desktop apps only]" in that page?

I think the proper place for such code is mingw's winstorecompat library,
not Gnulib. Can you try to submit it there?
