卓越班同学的第二阶段任务:
你们需要在文档1的基础上完成如下内容:
新指令
createFile 在某个特定目录B下创建新的空文件A
>fs.exe createFile <目录B的路径> <空文件A的文件名>
insertFile 导入某个文件A到特定目录B下,参数1为目标路径,参数2为要添加的文件A的在系统中的绝对路径
>fs.exe insertFile <目录B的路径> <被导入文件A在系统中的路径>
createDirecotory 在某个特定目录B下添加子目录C
>fs.exe createDirecotory <目标B的路径> <要添加的目录C的名称>
提示:
1.因为文件系统是持久化存储设备,所以每次更新操作(添加文件或者目录)都需要将结果写回到diskblock.data文件,以使再次执行fs.exe时能够看到这些修改。
2.为了添加新的目录和文件,你需要编写一些函数查找空闲的inode和block,我们不对查找策略进行要求,你可以从恰当的起始位置开始,选取第一个空闲的inode或者block
3.每次申请了新的block后,请将bitmap for free blocks相应的bit设置为1,表示占用。
You can’t perform that action at this time.
