[问题描述]
在任一OS下,建立一个大文件,把它假象成一张盘,在其中实现一个简单的 模拟UNIX文件系统 。
[基本要求]
1.在现有机器硬盘上开辟20M的硬盘空间,作为设定的硬盘空间。
2.编写一管理程序对此空间进行管理,以模拟UNIX(linux)文件系统,具体要求如下:
(1) 要求盘块大小1k
(2) i 结点文件类型 正规文件目录文件(共1byte)块设备 管道文件
。物理地址(索引表)
共有13个表项,每表项2byte
。文件长度 4byte
。联结计数 1byte-[Descr iption of the problem] in any OS, the establishment of a large file, put it into a false impression disk, in which the realization of a simple simulation of UNIX file system. [Basic requirements] 1. In the existing machine s hard drive to open up 20M of hard disk space, as a set of hard disk space. 2. The preparation of a management process to manage this space to simulate UNIX (linux) file system, the specific requirements are as follows: (1) request the disk block size 1k (2) i-node directory file type formal document files (a total of 1byte) block device pipeline文件. Physical Address (Index Table) A total of 13 tables, each table entry 2byte. The length of documents 4byte. Link count 1byte
