Re^5: Private temporal files on Windows

Anyway, I still have to check that the file handle survives the full chain of program calls (perl -> sshg3 -> cmd -> helper)

It doesn't, the file handle is not inherited by sshg3 children.

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 :-/	[reply] [d/l] [select]

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.	[reply]
