That's fabulous, many thanks!!!

*nods* Guessing the mode in the POSIX world requires going into
fcntl() territory. It's not hard, but it's definitely not portable.
I wouldn't mind figuring out how to do it in Windows, but I don't have
a Windows box on which to test it, so it wouldn't be fair for me to
call for that feature. Anyway, I'm a POSIX-world person so I could
easily write my own wrapper for your new function that invokes fcntl()
on the fd.
Many many thanks!
