如何用汇编语言编一个让计算机关机的程序

在MASM32下代码如下:

.486 create 32 bit code

.model flat, stdcall 32 bit memory model

option casemap :none case sensitive

include \masm32\include\windows.inc

include \masm32\include\kernel32.inc

includelib \masm32\lib\kernel32.lib

.data

strShutDown db "shutdown.exe /s /s /t 00",0

.code

start:

invoke WinExec,addr strShutDown,0

invoke ExitProcess,0

end start

在MASM32下代码如下:

.486 create 32 bit code

.model flat, stdcall 32 bit memory model

option casemap :none case sensitive

include \masm32\include\windows.inc

include \masm32\include\kernel32.inc

includelib \masm32\lib\kernel32.lib

.data

strShutDown db "shutdown.exe /s /s /t 00",0

.code

start:

invoke WinExec,addr strShutDown,0

invoke ExitProcess,0

end start

可以，下面是最真的C语言代码，基本是嵌入汇编的。关于中断。。

有些都是靠调用系统的内部命令完成的 ，如楼上的 system("shutdown -s -t 0")在这个函数里面可以输入DOS命令都可以，所以只是个DOS命令而已。

＝＝＝＝＝＝＝＝＝ for Dos =======================

#include<stdio.h>

#include<dos.h>

void main( void )

{

union REGS In,Out

In.x.ax = 0x5300/*检查是否支持APM*/

In.x.bx = 0x0000

int86(0x15,&In,&Out)

if( Out.x.cflag != 0)

{

printf("No APM!\n")

exit(0)

}

In.x.ax = 0x5301/*连接到APM*/

In.x.bx = 0x0000

int86(0x15,&In,&Out)

if( (Out.x.cflag!=0) &&(Out.h.ah!=0x02))

{

printf("Connecting error!\n")

exit(0)

}

In.x.ax = 0x530e/*通知APM所使用的版本为1.2*/

In.x.cx = 0x0102

int86(0x15,&In,&Out)

if( (Out.x.cflag != 0)

{

printf("Ver error!\n")

exit(0)

}

In.x.ax = 0x5307/*实现关机*/

In.x.bx = 0x0001

In.x.cx = 0x0003

int86(0x15,&In,&Out)

if( (Out.x.cflag != 0)

{

printf("Shutdown error!\n")

exit(0)

}

}
