在网上找到的方法一般是用DeviceIoControl、ReadFile、WriteFile等，但是用这些方法的前提是先调用 CreateFile，这个函数的第一个参数是一个SymbolicLink（例如："\\\\.\\TestSample"），这个 SymbolicLink一般是在驱动程序中调用IoCreateSymbolicLink创建的，这样的驱动程序一般有类似如下入口例程：
NTSTATUS DriverEntry(IN PDRIVER_OBJECT DriverObject,IN PUNICODE_STRING RegistryPath)
{
PFILE_OBJECT pLowerFileObject=NULL;
UNICODE_STRING DeviceName;
UNICODE_STRING DosDeviceName;
UNICODE_STRING Name;
PDEVICE_OBJECT pLowerDeviceObject=NULL;
PDEVICE_OBJECT pDeviceObject=NULL;
NTSTATUS Status;

DriverObject->DriverUnload=DriverUnload;
DriverObject->MajorFunction[IRP_MJ_READ] = TestSampleRead;
DriverObject->MajorFunction[IRP_MJ_WRITE] = TestSampleWrite;
DriverObject->MajorFunction[IRP_MJ_CREATE] = TestSampleCreate;
DriverObject->MajorFunction[IRP_MJ_CLOSE] = TestSampleClose;
DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL] = TestSampleDeviceControl;
RtlInitUnicodeString(&DeviceName,gDeviceName);
RtlInitUnicodeString(&DosDeviceName,gDosDeviceName);
IoCreateDevice(DriverObject,0,&DeviceName,FILE_DEVICE_UNKNOWN,0,FALSE,&pDeviceObject);
pDeviceObject->Flags|=DO_BUFFERED_IO;
Status = IoCreateSymbolicLink(&DosDeviceName,&DeviceName);
if(Status)
DbgPrint("IoCreateSymbolicLink Return %0x\n",Status);
KeInitializeSpinLock(&gSpinLock);
RtlInitUnicodeString(&Name,gKeventName);
pMsgKEvent = IoCreateSynchronizationEvent(&Name,&hMsgEvent);
Status = ObReferenceObjectByHandle(hMsgEvent,EVENT_ALL_ACCESS,*ExEventObjectType,KernelMode,(PVOID*)&gKeventObject,NULL);
if(!NT_SUCCESS(Status))
{
DbgPrint("SDbgMsg : ObReferenceObjectByHandle\n");
}
else
{
DbgPrint("gKeventObject = %x pMsgKEvent=%x\n",gKeventObject,pMsgKEvent);
}
if(gKeventObject)
KeClearEvent(gKeventObject);
if(pMsgKEvent)
KeResetEvent(pMsgKEvent);

return 0;
}

我现在碰到一个这样的驱动程序，它的入口例程如下：
ULONG
DriverEntry (
IN PDRIVER_OBJECT DriverObject,
IN PUNICODE_STRING RegistryPath
)
{
HW_INITIALIZATION_DATA HwInitData;
ULONG ReturnValue;

RtlZeroMemory(&HwInitData, sizeof(HwInitData));

HwInitData.HwInitializationDataSize = sizeof(HwInitData);

//
// Set the Adapter entry points for the driver
//

HwInitData.HwInterrupt = NULL; // HwInterrupt;

HwInitData.HwReceivePacket = AdapterReceivePacket;
HwInitData.HwCancelPacket = AdapterCancelPacket;
HwInitData.HwRequestTimeoutHandler = AdapterTimeoutPacket;

HwInitData.DeviceExtensionSize = sizeof(HW_DEVICE_EXTENSION);
HwInitData.PerRequestExtensionSize = sizeof(SRB_EXTENSION);
HwInitData.FilterInstanceExtensionSize = 0;
HwInitData.PerStreamExtensionSize = sizeof(STREAMEX);
HwInitData.BusMasterDMA = FALSE;
HwInitData.Dma24BitAddresses = FALSE;
HwInitData.BufferAlignment = 3;
HwInitData.DmaBufferSize = 0;

// Don't rely on the stream class using raised IRQL to synchronize
// execution. This single paramter most affects the overall structure
// of the driver.

HwInitData.TurnOffSynchronization = TRUE;

ReturnValue = StreamClassRegisterAdapter(DriverObject, RegistryPath, &HwInitData);

return ReturnValue;
}
我现在不知道怎么跟这样的驱动程序通讯啊，大虾们帮帮忙啊。

DELPHI如果不用DDK，永远不能做出像“冰点”这样的软件了。。。。。。。。。。。。

移到C++去吧, D版估计搞DDK的比较少.

我在VC版也发了帖子，没有得到很好的答复，发在这里主要是想让ly帮着看看，他居然没来。。。到时候散分。

>> “CreateFile打开sys得到句柄”

修改一下：

CreateFile打开 驱动创建的设备，

才看见这个贴的
这个应该是Stream Mini驱动,是物理硬件的驱动,而不是R0的软件(应用)驱动

应用层和sys通讯，都是使用IRP 请求的，
即用CreateFile打开sys得到句柄,再调用DeviceIoControl往这个sys，发送I/O控制码 进行通讯

所以，sys要能接收并处理，应用层发送过来的IO请求才行，

如例子1：
DriverObject- >MajorFunction[IRP_MJ_READ] = TestSampleRead;
DriverObject- >MajorFunction[IRP_MJ_WRITE] = TestSampleWrite;
DriverObject- >MajorFunction[IRP_MJ_CREATE] = TestSampleCreate;
DriverObject- >MajorFunction[IRP_MJ_CLOSE] = TestSampleClose;
DriverObject- >MajorFunction[IRP_MJ_DEVICE_CONTROL] = TestSampleDeviceControl;

它可以处理的IO请求有：IRP_MJ_READ、IRP_MJ_WRITE，IRP_MJ_DEVICE_CONTROL...

而楼主碰到驱动，要通讯的话，也要能接收和处理 IRP
