How can I free built-in data token in static area
<p>How can I free built-in data token in static area over using static keyword after a some time pass or when some condition meet ?</p>

<p>ex;</p>

<pre><code>   int func2 ( void ) {
      static int i = 0 ;

      // some work ;
      if ( i == 20 ) {
          return i ;
          // some thing to give  static memory place to memory  
   }
   }

   int main ( void ) {
      //under some condition, call func2 iteratively
      // when return value is 20, then break the iteration
   }
</code></pre>
