labs() is C-specific, see L<perlfunc/abs> instead.
+=item lchown
+
+This is identical to the C function, except the order of arguments is
+consistent with Perl's builtin C<chown()> with the added restriction
+of only one path, not an list of paths. Does the same thing as the
+C<chown()> function but changes the owner of a symbolic link instead
+of the file the symbolic link points to.
+
=item ldexp
This is identical to the C function C<ldexp()>
