GNU CLISP: finding the modification time of a file

Question

I'm coding for GNU CLISP:

GNU CLISP 2.48 (2009-07-28)

I guess I have two questions:

1. How do I find when a file was last modified, using CLISP's POSIX package?

2. Where could I have looked to find this answer for myself?

Answer 1

• Posix:file-stat returns a structure with a slot mtime.

• Search for "clisp posix file date" (I used duckduckgo): http://www.clisp.org/impnotes/syscalls.html
