I was at Marcus Ranum's Usenix '97 tuturial on Coding for Hostile Environments, and the subject came up of creating temporary files securely. Open-then-unlink leaves a window for someone to get at the file. Has there been any discussion here of adding, e.g., an O_UNLINK flag to open (), that would effectively create an anonymous temp file?
