Description: 编写C语言程序,模拟UNIX磁盘空间管理中使用的分组链接法。
1.定义一个记录磁盘块号的堆栈S—free[10],以及记录栈中现有磁盘块数的变量S—nfree。
2.定义一个由40个元素构成的结构数组block[40]用作磁盘块存放。
struct size

}
struct blocd
{ struct size a[10]
//用于在空闲磁盘块号链中存放磁盘块号
}block[40]
3. 假设系统中文件的最大容量为100个磁盘块,且最多只有5个文件,定义一个由5个元素构成的结构数组file[5]用于记录各个文件占用的磁盘块,。

4. 编写函数init( )完成空闲磁盘块号堆栈、空闲磁盘块号队列及记录文件占用磁盘块状态的file结构数组。
5. 编写函数alloc(fileno,blockd),完成磁盘块的分配操作。其中的参数fileno为文件序号,用于指定需要分配的文件。
6. 编写函数free(fileno),完成文件占用磁盘块的释放操作。其中的参数fileno为文件序号,用于指定需要释放磁盘块的文件。
7. 编写main( )函数完成下列操作:
调用init( )函数完成初始设置。
从终端输入命令,控制磁盘块的分配与回收操作。

Description: 用C语言模拟小型类UNIX文件系统, 文件系统被分成三个部分,依次为:位视图,I节点区和数据区。数据区被分成1024块,每块有1024个字节。用一个文件模拟外存,在程序中用数组分别模拟内存中的I节点,位图,文件系统。在每一次的操作中如果相应元素有变动,则对应在文件中更新输出相应数据。-Small classes in C language simulation UNIX file system, file system is divided into three parts, as follows: bit view, I node area and data area. Data area is divided into 1024 blocks, each block is 1024 bytes. Simulate external memory with a file, were simulated in the program memory array using the I node, bitmap, the file system. In every operation the corresponding element if there are any changes, then the corresponding output in the file, update the corresponding data. Platform: |
