*   使用說明：                                       * 
*      要定義一個(gè)菜單，需要做以下幾步工作            * 
*      1、定義一個(gè)結(jié)構(gòu)體數(shù)組                         * 
*      2、如果這個(gè)菜單是子菜單，那么把上級菜單的     * 
*         *ChildrenMenus指針指向該數(shù)組的首地址,      * 
*         并且設(shè)置ParentMenus為上層目錄的地址        * 
*      3、如果這個(gè)菜單是 根菜單，那么直接將MenuPoint * 
*         指針指向該數(shù)組的首地址                     * 
*      4、通過寫一個(gè)函數(shù)為該數(shù)組的每一個(gè)元素初始化   * 
*      5、如果菜單項(xiàng)是最終選項(xiàng)，那么將*ChildrenMenus * 
*         置為NULL，將函數(shù)指針*Subs指向?qū)崿F(xiàn)功能的    * 
*         函數(shù)。                                     *
