求助：debug出现了错误

我的程序每次debug到deviceiocontrol()时，就会提示说指令引用的内存不能为write.但事实上我的outBuffer指向的一个数组的起始地址，应该不存在指针错误。
下面是程序：
UINT WriteProc(
LPVOID
)
{
BOOLEAN bResult;
short outBuffer[512];
ULONG OutPacketSize;

if (WriteLength()>=MAX_BUFFER_SIZE)
{
OutPacketSize=MAX_BUFFER_SIZE;
}
else
{
OutPacketSize=WriteLength();
}

WriteCompleteEvent=CreateEvent(0,FALSE,FALSE,NULL);

BULK_TRANSFER_CONTROL OutBulkControl;

if (bOpenDriver (&hOutDevice) != TRUE)
{
AfxMessageBox(\"Failed to open the device\",MB_OK);
hOutDevice = NULL;
}

OutBulkControl.pipeNum=0;
if (hOutDevice != NULL)
{
for (int i=0;i<OutPacketSize;i++)
outBuffer = WriteDeQueue ();
bResult=DeviceIoControl(hOutDevice, IOCTL_EZUSB_BULK_WRITE,
&OutBulkControl,
sizeof(BULK_TRANSFER_CONTROL),
outBuffer,
OutPacketSize,
0,
NULL);

if (WriteCompleteEvent)
SetEvent(WriteCompleteEvent);
suswrite=1;
CloseHandle(hOutDevice);
}
return bResult;
}

上面是辅助线程函数，下面是主程序：
CWinThread* myWriteThread = AfxBeginThread (WriteProc,NULL,THREAD_PRIORITY_HIGHEST,0,0,NULL);

每次debug运行到DeviceIoControl（）时就会提示指令引用的内存不能为write?.

大家帮帮忙，这程序到底错在哪里？
我自己是怎么也看不出来了。
bow,bow

  bResult=DeviceIoControl(hOutDevice, IOCTL_EZUSB_BULK_WRITE,
     &OutBulkControl,
     sizeof(BULK_TRANSFER_CONTROL),
     outBuffer,
     OutPacketSize,
     0,
     NULL);

改为：
 DWORD ret;
  bResult=DeviceIoControl(hOutDevice, IOCTL_EZUSB_BULK_WRITE,
     &OutBulkControl,
     sizeof(BULK_TRANSFER_CONTROL),
     outBuffer,
     OutPacketSize,
     &ret,
     NULL);

 bResult=DeviceIoControl(hOutDevice, IOCTL_EZUSB_BULK_WRITE,
     &OutBulkControl,
     sizeof(BULK_TRANSFER_CONTROL),
     outBuffer,
     OutPacketSize,
     0,
     NULL);

改为：
 DWORD ret;
  bResult=DeviceIoControl(hOutDevice, IOCTL_EZUSB_BULK_WRITE,
     &OutBulkControl,
     sizeof(BULK_TRANSFER_CONTROL),
     outBuffer,
     OutPacketSize,
     &ret,
     NULL);

我漏掉了这里。

给你加分。
