  使用者自定主選單(2) 編輯自定主選單

: menu.c 一開始

extern UCACHE *ushm;

+ static int launch_set();

: menu.c 在適當的選單加入

+ launch_set, PERM_VALID, M_XMODE,
+ "Menu       《 自定選單 》",

: menu.c 最後加入以下這整段

/* ----------------------------------------------------- */
/* 使用者自定 Quick Launch                               */
/* ----------------------------------------------------- */
