void
mysql_free_result(MYSQL_RES *result)Note
            mysql_free_result() is a
            synchronous function. Its asynchronous counterpart is
            mysql_free_result_nonblocking(),
            for use by applications that require asynchronous
            communication with the server. See
            Chapter 7, C API Asynchronous Interface.
          
          mysql_free_result() frees the
          memory allocated for a result set by
          mysql_store_result(),
          mysql_use_result(),
          mysql_list_dbs(), and so
          forth. When you are done with a result set, you must free the
          memory it uses by calling
          mysql_free_result().
        
Do not attempt to access a result set after freeing it.
