怎样可以得到cpu的ID?

怎样得到CPU的ID?有标准的函数吗?

[masterz]

#include <stdio.h>
#include <conio.h>

int main(int argc,char **argv)
{
unsigned long s1,s2;
unsigned char vendor_id[]="------------";
char sel;
printf("Select the function:\n1-------Read CPU id.\n2-------Disable CPU id.\n");
sel=getch();
switch(sel)
{
case '1':
__asm{
xor eax,eax
cpuid
mov dword ptr vendor_id,ebx
mov dword ptr vendor_id[+4],edx
mov dword ptr vendor_id[+8],ecx
}
printf("%s-",vendor_id);
__asm{
mov eax,01h
xor edx,edx
cpuid
mov s1,edx
mov s2,eax
}
printf("%08X\n%08X-",s1,s2);
__asm{

mov eax,03h
xor ecx,ecx
xor edx,edx
cpuid
mov s1,edx
mov s2,ecx
}
printf("%08X-%08X\n",s1,s2);
break;
case '2':
{
__asm{

mov ecx,119h
rdmsr
or eax,00200000h
wrmsr
}
}
printf("CPU id is disabled.\n");
break;
}
return 0;
}

用ASM指令！

[howtotell]

/*
函数：取得CPU启动到现在运行的周期数
*/
_int64 CSystemInfo::Count(void)
{
_asm
{
_emit 0x0F
_emit 0x31
}

}


/*
函数：取得CPU信息
*/
void CSystemInfo::GetCpu()
{
CString m_strCpuInfo;
m_strCpuInfo.Empty();
char OEMString[13];

int iEAXValue,iEBXValue,iECXValue,iEDXValue;

_asm {
mov eax,0
cpuid
mov DWORD PTR OEMString,ebx
mov DWORD PTR OEMString+4,edx
mov DWORD PTR OEMString+8,ecx
mov BYTE PTR OEMString+12,0
}

m_strCpuInfo.Format("%s",OEMString);

_asm {
mov eax,1
cpuid
mov iEAXValue,eax
mov iEBXValue,ebx
mov iECXValue,ecx
mov iEDXValue,edx
}

if(iEDXValue&0x800000)
{
m_strCpuInfo+=" MMX Support";
}
else
{
m_strCpuInfo+=" No MMX Support";
}
int iCPUFamily=(0xf00 & iEAXValue)>>8;

CString m_family;
m_family.Format("%s%d","\r\n Family: ",iCPUFamily);
m_strCpuInfo+=m_family;

CString Frequency;
_int64 start=Count();
Sleep(1000);
_int64 stop=Count();
UINT cpuspeed = (UINT)((stop-start)/1000000);
Frequency.Format("%d MHZ",cpuspeed);
CString cpuinfo;
cpuinfo.Format("%s%s","频率: ",Frequency);
m_strCpuInfo+=cpuinfo;
strcpy(cpu,m_strCpuInfo);

}

怎么用？？
请指教？
