Ar an cúigiú lá déag de mí na Samhain, scríobh Stephen J. Turnbull: http://google.com/codesearch?hl=de&lr=&q=file%3A%5C.el+%27excl%5B... apel/poe.el gnus/mm-util.el gnus/nnmaildir.el ediff-util.el And in make-temp-file, the function I just merged. There’s no other way, beyond using write-region-internal--not portable to GNU--to access this functionality--avoiding the race condition between checking for a file’s existence and creating it. It’s ugly, but it is a positive feature. OK. I’m not sure you’re clear on the point of the MUSTBENEW argument. To make the check-for-an-existing-file-if-it-doesn’t-exist-create-it operation atomic¹--which it needs to be to avoid security issues for temporary files--it needs to be done in the OS kernel. Which means a subr is needed to expose it to Lisp. Which means it needs to be done at this level. Yeah, that’s a much nicer docstring. Yes. I agree that would be a better interface. It’s unhelpfully incompatible, though. That would be a little friendlier for most people most of the time, yes. I copied the logic from GNU, though, so I didn’t write it like that. FreeBSD: ‘If O_EXCL is set with O_CREAT and the file already exists, open() returns an error. This may be used to implement a simple exclusive access locking mechanism. If O_EXCL is set and the last component of the pathname is a symbolic link, open() will fail even if the symbolic link points to a non-existent name.’ I read that to mean that O_EXCL does have function when O_CREAT isn’t set, but I admittedly haven’t written any code to test that understanding. ¹ In the sense that it cannot be interrupted by other processes and resumed. -- ¿Dónde estará ahora mi sobrino Yoghurtu Nghé, que tuvo que huir precipitadamente de la aldea por culpo de la escasez de rinocerontes? _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-patches
