[Differential] [Updated] D3392: winutils_p.h: Restore compatibility with WinXP SDK

[brauch (Sven Brauch)]

brauch added a comment.


  Hm, there is at least one race condition here: thread A does old = ::SetErrorMode(...), then if before it resets it thread B does the same, then the old mode might never be restored. We can put a mutex but of course there might be another piece of code which does the same. So *shrug* not sure what to do, I guess it's just bad API and that's why MS replaced it.
  
  Maybe on XP we should just set the flag once on startup? At least that's not racy.
