Re^6: Private temporal files on Windows

You could try to use the technique from FDPasser to pass the filehandle as a string in %ENV to the helper process... But then I guess you could pass the information via %ENV already :-/

Well, that led me into using OpenProcess+DuplicateHandler to get the handler from the perl process into the helper and it works!

On the other hand, how secure is that? I guess only processes from the same user would be able to reopen handlers.

I will post a link to the code once I clean it.
