Yes and no. Unix does have files that do not have names in any directory. What it does not have is creation of such files without the existence (even transiently) of any name for them. To the extent that "Unix" is a single thing, that is. It wouldn't surprise me if some Unix variants had a way to do this. (If you're willing to accept a name in a directory which does not have a name anywhere except for its own ".", many of them do.) > You're talking about VMS, where you can open a file by file id.

See NetBSD's (and probably others') fhopen, for example. It's restricted to root, but it exists. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML [EMAIL PROTECTED] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B _______________________________________________ Secure Coding mailing list (SC-L) SC-L@securecoding.org List information, subscriptions, etc - http://krvw.com/mailman/listinfo/sc-l List charter available at - http://www.securecoding.org/list/charter.php SC-L is hosted and moderated by KRvW Associates, LLC (http://www.KRvW.com) as a free, non-commercial service to the software security community. _______________________________________________
