What about using the tempnam() call? Maybe it's not available on all
platforms although it is on AIX, SCO and HP-UX, so I'd have thought it
would be.
Do you feel that the randomness of the filenames this returns is not
random enough? Or is it that the very nature of a file that the world can
get at is the security threat, no matter what permissions are in
existence. I'd have thought that having /tmp mode 1777, using tempnam()
to get the file name, and creating this file in mode 0600 would be
sufficient.
