掌握UNIX外存空间管理中的分组链接算法



1.　　在程序运行的结果中应包含磁盘块的分配与回收操作。

2.　　可根据输入的文件名、文件大小进行模拟磁盘分配，并在每次分配与回收后显示分配与回收是否成功，以及分配、回收的磁盘块号。

3.　　在程序执行过程中，至少应包含分配不成功一次的信息。

4.　　可以查看当前磁盘块的使用情况：哪些块空闲，哪些块被哪些文件占用。

-UNIX external memory space management control block chaining algorithm in 1. The result of running the program should be included in the disk block allocation and recovery operations. 2. Can enter the file name, file size simulated disk allocation, distribution and recovery in each allocation and recovery after the show is successful, and the distribution, recovery of disk block number. 3. During program execution, at least one should include distribution of the information is unsuccessful. 4. You can view the current usage of disk blocks: which blocks free, which blocks are occupied by which files.
