实验要求如下

  1. 在内存中开辟一个虚拟磁盘空间作为文件存储器,在其上实现一个多用户多目录的文件系统。

  2. 文件物理结构可采用连续结构。

  3. 磁盘空闲空间的管理选择位示图。

  4. 文件目录结构采用多用户多级目录结构,每个目录项包含文件名、物理地址、长度等信息,还可以通过目录项实现对文件的读和写的保护。

  5. 设计一个较实用的用户界面,方便用户使用。要求提供以下相关文件操作: (1)具有login (用户登录) (2)系统初始化(建文件卷、提供登录模块) (3)文件的创建: create (4)文件的打开:open (5)文件的读:read (6)文件的写:write (7)文件关闭:close (8)删除文件:delete (9)创建目录(建立子目录):mkdir (10)改变当前目录:cd (11)列出文件目录:dir (12)退出:logout

  6. 系统必须可实际演示,选用程序设计语言:C++、C等。。
