Call function outside (function($){ })(jQuery);

Call function outside (function($){ })(jQuery);


I'm new to jQuery and working on a code now, I can't figure out how to call a function outside of the
(function($){    })(jQuery); tags. Here is a bit of my code:

<script type="text/javascript">

//Call the function from here

             // function I want to call:
            function testfunction (){
           //Some code...



I need this because the function call comes from an external file in my website.
Can anybody help me out???
