OEMIocontrol 中编写case IOCTL_GET_CACHE_INFO不知如何解决错误? [复制链接]

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:

                }else{
                 CACHE_INFO  pCacheInfo = (CACHE_INFO)lpOutBuf;
#define REQ_SIZE  dwL1ICacheSize+dwL1DCacheSize+dwL2ICacheSize+dwL2DCacheSize
                  if(sizeof(CacheInfo)>=REQ_SIZE){

缺少对应的头函数，要不就是你拼写错误。

IOCTL_GET_CACHE_INFO 是自定义的吧，看看文件之间的关系
