总看到有人发帖子问那个通用菜单程序中的几个错误不能编译的事,回去找了一下我修改后可以正常工作的程序,现贴出来,大家共享一下吧。 我的系统是scounix的。 编译 cc menu.c -o menu -lcurses 代码: /************************************************************** 本程序需要借肋两个参数文件来实现: (1)、对菜单中每一项参数进行说明的文件(menu.def),它格式如下所述: !所属菜单代号!项顺序号!菜单项名称!外挂程序名称!下级菜单代号! 说明: 1、如菜单代号为"0",则表示此项属于主菜单; 2、如外挂程序名称为"0",则表示此菜单项对应的过程在菜单程序内部或对应于一个子菜单; 3、如下级菜单代号为"0",则表示此菜单项无下级子菜单; 4、项顺序号同时可作为菜单热键使用。 假如文件menu.def中有下面这一行: !0!3!格式化磁盘!format /dev/rfd0135ds18!0! 它表示主菜单的第三项为格式化磁盘,它对应的执行过程为 format /dev/rfd0135ds18,本项无子菜单。 如果用户想把自己编的实现查询功能程序XXX挂到本程序主菜单第4项上,则可在menu.def中增加下面 这一行: !0!4!查询!XXX!0! (2)、对各菜单参数进行说明文件(menu.conf),其格式如下所述: !菜单代号!上一级菜单代号!边框标志!菜单宽度!菜单行数!菜单列数!起始横坐标!起始纵坐标! 说明: 1、边框标志为"0"表示无框,为"1"表示有边框; 2、上级菜单代号为"-1",表示无上级菜单; 3、如菜单代号为"0",表示主菜单。 当用户对菜单显示样式不满意时,可通过调整此文件设计个性化的界面 ***************************************************************/ #include #include #define ESC 27 #define ENT 13 #define REFRESH 12 #define MAX_M 10 /* 菜单最大层数 */
