小型内存分配模块,用通用循环双向链表实现，改程序模拟系统malloc-Small memory allocation module, two-way linked list with the realization of general circulation, to process simulation system malloc

读取目录中的文件名，放到循环双链表中，按1查看前一个， 按2查看后一个，按3退出。 -Read files in the directory name into the circulation doubly linked list, press 1 View 2 View 3 exit.

题目:有n个人围成一圈,顺序排号,从第一个开始报数 (从1到3报数),凡报到3的人退出圈子,问最后最后留下 的是原来第几号的那位. 提示:用循环链表完成 -Title: n personal circle sequence Arranging reported from the first number (from 1 to 3 count off), who report 3 exit the circle, asked the final last left the orig

linux下简单学生操作系统的实现，双向循环链表的使用，数据结构中对于结构体的练习。(Linux simple calendar implementation, the use of curses library color change function, you can make the color more brilliant.)
