hard link? ==> Re: [plt-scheme] are some of the file system functions atomic?

Hi -

Is there a function for creating hardlinks (in supported OS)?  I thought
make-file-or-directory-link will do the trick but  not according to the doc
at
http://docs.plt-scheme.org/reference/Filesystem.html#(def._((quote._~23~25kernel)._make-file-or-directory-link))
.

Thanks,
yc
