OEMIocontrol 中编写case IOCTL_GET_CACHE_INFO不知如何解决错误?

不太会编代码，参考别的代码硬着头皮写了个case.问题较多
Line 250 case IOCTL_GET_CACHE_INFO:
            if(!lpOutBuf||(nOutBufSize < sizeof(CacheInfo))){
   SetLastError(ERROR_INVALID_PARAMETER);
return FALSE;
}else{
   CACHE_INFO  pCacheInfo = (CACHE_INFO)lpOutBuf;
#define REQ_SIZE  dwL1ICacheSize+dwL1DCacheSize+dwL2ICacheSize+dwL2DCacheSize
               if(sizeof(CacheInfo)>=REQ_SIZE){
         nOutBufSize=REQ_SIZE;
sizeof(CacheInfo)=REQ_SIZE;
pCacheInfo.dwL1Flags=CF_UNIFIED;
pCacheInfo.dwL1ICacheSize=32;
