lchown(*args)
Equivalent to File::chown, but does not follow symbolic links (so it will change the owner associated with the link, not the file referenced by the link). Often not available. Returns number of files in the argument list.
static VALUE rb_file_s_lchown(int argc, VALUE *argv) { struct chown_args arg; apply2args(2); arg.owner = to_uid(*argv++); arg.group = to_gid(*argv++); return apply2files(lchown_internal, argc, argv, &arg); }
