close.c

操作系统实验,文件系统,c语言实现的

#include <stdio.h>
#include "filesys.h"

close(unsigned int user_id,unsigned short cfd)    /*close*/
{
   struct inode  *inode;
   inode=sys_ofile[user[user_id].u_ofile[cfd]].f_inode;
   iput(inode);
   sys_ofile[user[user_id].u_ofile[cfd]].f_count --;
   user[user_id].u_ofile[cfd]=SYSOPENFILE+1;
}
