KernelIoControl找设备号的问题
　　
if(!KernelIoControl(IOCTL_HAL_REQUEST_SYSINTR,&g_Irq,sizeof(UINT32),&g_SysIntr,sizeof(UINT32),NULL))
{
RETAILMSG(1,TEXT("ERROR:Failed to request sysintr value for Timer1 inturrupt!/r/n"));
return;
}

我想通过这种方式找mobile设备号,但各参数是什么意思,参数值又是从哪里来的,怎么获取????请给我一个实例代码...

#include <WINIOCTL.H>

extern "C" __declspec(dllimport)
BOOL KernelIoControl(
DWORD dwIoControlCode, LPVOID lpInBuf, DWORD nInBufSize,
LPVOID lpOutBuf, DWORD nOutBufSize, LPDWORD lpBytesReturned
);

#define IOCTL_HAL_GET_DEVICEID CTL_CODE(FILE_DEVICE_HAL, 21, METHOD_BUFFERED, FILE_ANY_ACCESS)

CString GetSerialNumberFromKernelIoControl()
{
DWORD dwOutBytes;
const int nBuffSize = 4096;
byte arrOutBuff[nBuffSize];

BOOL bRes = ::KernelIoControl(IOCTL_HAL_GET_DEVICEID,
0, 0, arrOutBuff, nBuffSize, &dwOutBytes);

if (bRes) {
CString strDeviceInfo;
for (unsigned int i = 0; i<dwOutBytes; i++) {
CString strNextChar;
strNextChar.Format(TEXT("%02X"), arrOutBuff[i]);
strDeviceInfo += strNextChar;
}
CString strDeviceId =
strDeviceInfo.Mid(40,2) +
strDeviceInfo.Mid(45,9) +
strDeviceInfo.Mid(70,6);

return strDeviceId;
} else {
return _T("");
}
}

还请你帮一下,我是用c++,用不了CString,请帮我改一下.
