I have two proposals, which I will illustrate with the procedure 'chmod': * chmod can currently modify permissions of a file. This OBJECT argument identifying the file can currently be a filename or a port. Allow a =E2=80=98file in a directory=E2=80=99 object as well. This could be created with a procedure (make-path-at DIRECTORY-PORT FILENAME) This procedure does not perform any I/O, but rather constructs what is effectively is a pair (DIRECTORY-PORT . FILENAME) but with its own type. * Follow the C API, but with Scheme types. (chmodat DIRECTORY-PORT FILENAME MODE FLAGS) where FLAGS can include AT_SYMLINK_NOFOLLOW (from chmod(2) Linux man page) Any thoughts? Greetings, Maxime P.S.
