操作系统文件操作模拟实验
设计一个N个用户的文件系统,每次用户可保存L个文件,一次运行用户可以打开S个文件。
程序采用二级文件目录(即设置主目录MFD)和用户文件目录(UFD)。另外,为打开文件设置了运行文件目录,用户已打开文件表UOF.。
为了便于实现,对文件的读写作了简化,在执行读写命令时,只需改读写指针,并不进行实际的读写操作
-OS file operations simulation
Design an N-user file system, each user can be stored L file, first run the user can open S files.
The program uses two files directory (ie, set the home directory of the MFD) and user file directory (UFD). In addition, set to open the file run the file directory, the user has to open the file table UOF.
Has been simplified in order to facilitate the achievement of the file read and write, read and write command, simply change the read and write pointer, not the actual read and write operations
