用DeviceIoControl这样通信为什么会蓝屏

传输的数据结构
typedef struct DataTransfer
{
HANDLE hCurrentProcess;
PROC* DatapfnNew;
PROC* Datappfn;
int isize;
};
应用层
DataTransfer* datatransferin;
DataTransfer* datatransferout;
int iLengthIn=sizeof(DataTransfer);
int iLengthOut=sizeof(DataTransfer);
datatransferin=new DataTransfer;
datatransferout=new DataTransfer;
        datatransferin->DatapfnNew=&pfnNew;
datatransferin->Datappfn=ppfn;
datatransferin->isize=sizeof((*ppfn));
datatransferin->hCurrentProcess=GetCurrentProcess();
HANDLE g_SysHandle = ::CreateFile("\\\\.\\Apihook.vxd"
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_FLAG_DELETE_ON_CLOSE,//FILE_ATTRIBUTE_NORMAL,
NULL
);
BOOL bRc = ::DeviceIoControl(g_SysHandle,
HOOK_DATA_PROCESS,
&datatransferin,
iLengthIn,
&datatransferout,
iLengthOut,
NULL,
NULL
);
delete datatransferin;
delete datatransferout;
CloseHandle(g_SysHandle);
驱动层
DataTransfer* datatransferin;
DataTransfer* datatransferout;
datatransferin=new DataTransfer;
datatransferout=new DataTransfer;
memcpy(&datatransferin,(DataTransfer*)pDIOCParams->dioc_InBuf,sizeof(DataTransfer));
datatransferout->isize=datatransferin->isize;
int size=pDIOCParams->dioc_cbOutBuf;
memcpy((DataTransfer*)pDIOCParams->dioc_OutBuf,&datatransferout,sizeof(DataTransfer));
delete datatransferin;
delete datatransferout;

另外
BOOL bRc = :eviceIoControl(g_SysHandle,
HOOK_DATA_PROCESS,
&datatransferin,
iLengthIn,
&datatransferout,
iLengthOut,
NULL,
NULL
);
修改为
BOOL bRc = :eviceIoControl(g_SysHandle,
HOOK_DATA_PROCESS,
datatransferin,
iLengthIn,
datatransferout,
iLengthOut,
NULL,
NULL
);

如果是你自己写的驱动，仔细检查驱动代码，没什么说的，你的驱动程序有问题。如果不是你开发的，下载新启动。

我按照前面的例子重新改了一下，蓝屏问题解决了。

我想问一下，当应用程序调用DeviceIoControl函数成功后，驱动中应该实现什么函数来响应它?

发送特定 IRP，驱动响应~~
