地址转换的问题，如何将驱动层的地址转换为WIN32应用程序的地址

做了一个测试发现用DEVICEIOCONTROL到驱动读数值，传进去的入
参发生了变换，本来是传一个地址为0x00867654 进去就变成了
其他值，所以如果要取某程序传到驱动的一个地址参数，肯定要
经过转换才能得到该参数在此程序中的虚拟地址，不过不知道怎么
转换还请多多指教。

下面的程序是用DS做的，可以的。你是用DS做的吗？
    KMemoryToProcessMap* MemRegion;//定义到XXXDevice类的头文件中。

NTSTATUS SX5933Device::IOCTL_MEM_Handler(KIrp I)
{
NTSTATUS status = STATUS_SUCCESS;

t << \"Entering SX5933Device::IOCTL_MEM_Handler, \" << I << EOL;
// TODO: Verify that the input parameters are correct
// If not, return STATUS_INVALID_PARAMETER

// TODO: Handle the the IOCTL_MEM request, or
// defer the processing of the IRP (i.e. by queuing) and set
// status to STATUS_PENDING.
ULONG Address=Phy_Address.LowPart;

MemRegion = new (NonPagedPool) KMemoryToProcessMap(Address,    // peripheral memory address
 mem_length,  // number of bytes
 (HANDLE)-1,  // current process
 FALSE,       // don\'t do kernel mapping
 NULL,        // any address
 ViewShare);  // view inherit
if ( !MemRegion||!NT_SUCCESS( MemRegion->ConstructorStatus() ) )
{
  // insufficient memory
  I.Information() = 0;
  return FALSE;
}
((Mem_Param*)I.IoctlBuffer())->mdr_PhysicalAddress=Address;
((Mem_Param*)I.IoctlBuffer())->mdr_LinearAddress=MemRegion->ProcessAddress();
// TODO: Assuming that the request was handled here. Set I.Information
// to indicate how much data to copy back to the user.
I.Information() = sizeof(ULONGLONG);

return status;
}
用完了别忘了UNMAP一下：（
NTSTATUS SX5933Device::IOCTL_UNMEM_Handler(KIrp I)
{
NTSTATUS status = STATUS_SUCCESS;

t << \"Entering SX5933Device::IOCTL_UNMEM_Handler, \" << I << EOL;
// TODO: Verify that the input parameters are correct
// If not, return STATUS_INVALID_PARAMETER

// TODO: Handle the the IOCTL_UNMEM request, or
// defer the processing of the IRP (i.e. by queuing) and set
// status to STATUS_PENDING.
delete MemRegion;
// TODO: Assuming that the request was handled here. Set I.Information
// to indicate how much data to copy back to the user.
I.Information() = 0;

return status;
}

我是用DDK做的用 ,先谢过了：）
回去试一下
