Common Lisp function or idiom for creating a temporary file name?

Question

Is there a Common Lisp function or typical way for creating a temporary file name or file?

Answer 1

Update since a few years have passed. There are two systems that can open a temporary file not previously mentioned, cl-fad and UIOP. They are both in quicklisp, and UIOP is part of ASDF3, which comes with most CL implementations now.

Answer 2

There is no function for that in common lisp. Allegro has make-temp-file-name, Emacs has make-temp-file, clisp has mkstemp.
