写作计画掩饰隔墙

由于节目是用来掩盖下利用隔墙隔墙,隔墙进入膜生物反应器由划分表. 如果你想掩饰其它逻辑间隔延长膜生物反应器体积要进入延长.

编码方案已获批准下一:

/*节目以隐瞒隔墙隔墙,隔墙从入境表膜*/

#include <bios.h>
#include <stdio.h>

int main(void)
{
struct diskinfo_t dinfo;
int result, tohide;
int i;
static char dbuf[512];/* 数据缓冲区读写行业信息 */
clrscr();

dinfo.drive = 0x80; /* 号码第一硬盘驱动 */
dinfo.head = 0; /* 盘头数 */
dinfo.track = 0; /* 轨道数目 */
dinfo.sector = 1; /* 业人数 */
dinfo.nsectors = 1; /* 计数界 */
dinfo.buffer = dbuf; /* 数据缓冲区 */

/* 经过首盘界 */

result = _bios_disk(_DISK_READ, &dinfo);

if ((result & 0xff00) == 0)
{
printf("The Partition Codes of Four Partition Entries are,
0x%02x, 0x%02x, 0x%02x And 0x%02x.\n",
dbuf[450] & 0xff, dbuf[466] & 0xff,
dbuf[482] & 0xff, dbuf[498] & 0xff);

gotoxy(10,9);cprintf("3. "); showtype(dbuf[482] & 0xff);
gotoxy(10,10);cprintf("4. "); showtype(dbuf[498] & 0xff);

/*让使用者输入隐瞒隔墙*/

gotoxy(1,15);

Or Press any other key to Exit... ");

tohide=getche();

switch(tohide)
{
case '1': /* 隐藏在第一隔墙隔墙表 */
dbuf[450] = dbuf[450] +16;

}

{
printf("\n\nThe New Partition Codes of Four Partition
Entries are, 0x%02x, 0x%02x, 0x%02x And 0x%02x.\n",
dbuf[450] & 0xff, dbuf[466] & 0xff,
dbuf[482] & 0xff, dbuf[498] & 0xff);

评论代码:

节目内容全部文件系统标志字节的条目划分表划分四个膜. showtype()的功能是用来显示档案名称档案制度相应价值指标体系字节.

用户选择分割躲避菜单显示在屏幕上,再增加16(0x10)的价值指标字节的文件系统,隔墙隐瞒.

编码的功能showtype()如下:

/*功能说明文件系统的名字对应于档案系统的价值指标字节*/

showtype(i)
{
switch (i)
{

case 0x00 :cprintf("Empty"); break;
case 0x01 :cprintf("DOS 12-bit FAT"); break;
