close.c

基于UNIX6的文件系统模拟程序

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


close(user_id,cfd)
unsigned int user_id;
unsigned short cfd;
{
	struct inode *inode;

	inode = sys_ofile[user[user_id].u_ofile[cfd]].f_inode;
//	printf("in close %d",inode->di_size);
	iput(inode);
	sys_ofile[user[user_id].u_ofile[cfd]].f_count--;
	user[user_id].u_ofile[cfd]=SYSOPENFILE+1;
}
