Linux平台下用curses库写的一个通用的图形化菜单生成程序

1.先来上一张程序执行后的界面：

2.C代码

注意：

a. 因为curses.h不是linux C默认的头文件，所以在编译时需要自己链接

b. 编译：gcc menu.c -lcurses -o menu [Linux-Fedora 14]

3.编写菜单配置文件menu.conf

注意：

a. menu.conf如果要改成其他名字，则编译时一定要[-o 你要修改的名字]，否则运行会得不到你想要的结果

b. 菜单中不要使用中文，否则生成的菜单会乱码

#
#   格式为: 菜单号|项目个数|项目名称......
#           菜单数量最大为10个
#
0|6|Choice1|Chioce2|Chioce3|Choice4|Choice5|Chioce6|
1|3|menu11|menu12|menu13|
2|8|menu21|menu22|menu23|menu24|menu25|menu26|menu27|menu28|
3|5|menu31|menu32|menu33|menu34|menu35|
4|4|menu41|menu42|menu43|menu44|
5|2|menu51|menu52|
6|1|menu61|
