 - Is it possible for the mirror driver does not support DrvBitBlt function? I'm writing a mirror driver based on the DDK mirror driver sample code. I read the documentation at the msdn library, and learned that if a driver manages its own surface, the driver must also, at a minimum, support DrvCopyBits, DrvTextOut, DrvStrokePath drawing functions. I noticed that DrvBitBlt was also in the DDK mirror driver sample code. When I hooked off the DrvBitBlt function, I got a blue screen. I'm trying to avoid implementing DrvBitBlt because of complexity. Could any guru tell if it is possible not to implement DrvBitBlt function in the mirror driver? Thanks, Tag: sharing memory user mode & virtual video capture driver Tag: 70749

 - Problem uninstalling keyboard driver Hi, I've written a keyboard driver for W2K/WXP which ties in with kbdclass and works fine. It happily sits next to a standard Windows keyboard driver in Device Manager. Problem is Device Manager gives no Uninstall option for my driver and DevCon reports "Remove failed" if I try to remove it. I've also written a touchscreen mouse driver which similarly connects with mouclass and sits next to a standard Windows mouse driver in Device Manager. This does have an uninstall option and can be removed using DevCon. Both drivers have a similar structure, but is there anything extra I should be doing in the keyboard driver to make it uninstallable? How should I go about uninstalling it? Thanks, Ade.

 - AVStream on Win98 Hi all, Help really needed... I have managed to build a AVStream driver for an USB device that runs on all platforms, except win98 se. According to the documentation of AVStream in MSDN, we can run any AVStream driver on any OS as long as the OS has DirectX ver8.0 and above. Exclamation mark is shown in the camera icon in the Device Manager and error code is "The NTKERN.VXD device loader(s) for this device could not load the device driver. (Code 2)". May I know is this problem due to AVStream? Please advise. Thank you very much. Tag: sharing memory user mode & virtual video capture driver Tag: 70744

 - Strange behaviour with USB selective suspend Hello I've connected a usb mouse in combination with our own usb device to the same root hub. Our device supports remote wake-up. The driver for our usb device sends down a request for usb selective suspend. Nothing happens. When I unplug the usb mouse, the system happely invokes the callback routine so the driver sets device power state D2. I find this behaviour a bit odd. Why does the usb mouse prevent our device from going into usb selective suspend? I also replaced the usb mouse with a different usb device but the behaviour remained the same. This is WinXP SP2. The implementation in our driver has passed whql. Tag: sharing memory user mode & virtual video capture driver Tag: 70743

 - USB stack gives misleading indications when Polling Interval not 1 I am seeing some incorrect indications from the usb stack (XP SP2) when my device indicates a Polling Interval of 2 on its isochronous endpoint: My hardware has a high speed (not high bandwidth) iso In endpoint; it generates fixed size 1000-byte packets at an interval very slightly over 250uS. I have taken the isousb sample from the 3790 DDK, and adapted it to work with my configuration. Because of the data rate, it seemed sensible to increase the polling interval on that endpoint so as to only poll every other microframe, so I set a value of two. I use the test app (rwiso) to read an amount of data from the device, and the driver output is as follows: IsoPacket[0].Length = 0x03E8 IsoPacket[0].Status = 0 IsoPacket[1].Length = 0x0000 IsoPacket[1].Status = 0 IsoPacket[2].Length = 0x03E8 IsoPacket[2].Status = 0 IsoPacket[3].Length = 0x0000 IsoPacket[3].Status = 0 IsoPacket[4].Length = 0x03E8 IsoPacket[4].Status = 0 IsoPacket[5].Length = 0x0000 IsoPacket[5].Status = 0 IsoPacket[6].Length = 0x03E8 IsoPacket[6].Status = 0 IsoPacket[7].Length = 0x0000 IsoPacket[7].Status = 0 IsoPacket[8].Length = 0x03E8 IsoPacket[8].Status = 0 IsoPacket[9].Length = 0x0000 IsoPacket[9].Status = 0 IsoPacket[10].Length = 0x03E8 IsoPacket[10].Status = 0 IsoPacket[11].Length = 0x0000 IsoPacket[11].Status = 0 IsoPacket[12].Length = 0x03E8 IsoPacket[12].Status = 0 IsoPacket[13].Length = 0x0000 IsoPacket[13].Status = 0 IsoPacket[14].Length = 0x03E8 IsoPacket[14].Status = 0 IsoPacket[15].Length = 0x0000 IsoPacket[15].Status = 0 IsoPacket[16].Length = 0x03E8 IsoPacket[16].Status = 0 IsoPacket[17].Length = 0x0000 IsoPacket[17].Status = 0 IsoPacket[18].Length = 0x03E8 IsoPacket[18].Status = 0 IsoPacket[19].Length = 0x0000 IsoPacket[19].Status = 0 IsoPacket[20].Length = 0x03E8 IsoPacket[20].Status = 0 IsoPacket[21].Length = 0x0000 IsoPacket[21].Status = 0 IsoPacket[22].Length = 0x03E8 IsoPacket[22].Status = 0 IsoPacket[23].Length = 0x0000 IsoPacket[23].Status = 0 So this suggests that every other packet is coming back zero-length. However, when I look at the entire buffer from the user-space app there are no gaps - every piece of data *is* there (and correct) from beginning to end - all 24 packets. The return value from the read() call is 12*1000 yet the whole buffer has in fact been written. I've also used SnoopyPro to examine what the stack thinks the packets contain, and diagrammatically (and very much simplified), this is what I'm seeing (with "." indicating a zero-length packet): According to stack Actually in buffer 0 1 2 3 0 1 2 3 . 4 5 6 7 8 9 A B 8 9 A B . C D E F 0 1 2 3 0 1 2 3 etc This is a problem to me because I will occasionally get genuine zero-length packets (due to the data generation being asynchronous to the usb frames), and I need to be able to detect them. The USBD_SHORT_TRANSFER_OK flag is not set. This only happens when the Polling Interval is 2; when it is set to 1 then the behaviour is as expected (albeit interspersed with genuine zero-length packets, generated by the h/w when it is polled but has no data available) I'm running a free build XP SP2, but with checked versions of ntoskrnl, hal, usbport.sys, usbccgp.sys and usbd.sys (also from an SP2 version). Is it a bug in the usb stack? There is a report of this kind of problem - http://support.microsoft.com/?kbid=837371 - but although it is dated only a few days ago, it seems to be saying that the issue is fixed in SP2; and I have newer versions of all the files indicated (though why don't I have usbccgp.sys - isn't that needed for composite devices??) [I'm having trouble with my Win2K installation at the moment, so I've not had a chance to compare]. In fact, as I repeat the test today to check my results (before hitting "Send"), I'm *also* now seeing an additional effect: a packet with a length of 1000, but contents all zero - but, again, without any loss of data - where there *is* data in the buffer it is continous and valid (the data stream contains a count to help spot discontinuities). What with the results I was seeing yesterday plus this additional weirdness I'm now seeing, I'm wondering if there are still issues with non-one values of polling interval? Anyone got any thoughts? Can anyone at MS confirm whether 837371 really is fixed? Thanks. Tag: sharing memory user mode & virtual video capture driver Tag: 70727

 - Windows Xp and interrupts. I'm writing a driver for programming performance counters in PIV processor. I've wrote bus driver which enumerates devices and allocates resources and function driver which will do main job. I'm having a problem with allocating resources for functional driver. Currently my IRP_MN_QUERY_RESOURCES handling function looks like this: static NTSTATUS HandleQueryResources(PDEVICE_OBJECT pdo, PIRP Irp) { NTSTATUS status = Irp->IoStatus.Status; PIO_STACK_LOCATION stack = IoGetCurrentIrpStackLocation(Irp); KdPrint((DRIVERNAME " (PDO) - HandleQueryRequirements\n")); PCM_RESOURCE_LIST resourceList; PCM_FULL_RESOURCE_DESCRIPTOR frd; PCM_PARTIAL_RESOURCE_DESCRIPTOR prd; ULONG resourceListSize; // // Following code shows how to provide // boot I/O port resource to a device. // resourceListSize = sizeof(CM_RESOURCE_LIST); resourceList = (PCM_RESOURCE_LIST)ExAllocatePoolWithTag (PagedPool, resourceListSize, APICBUS_POOL_TAG); if (resourceList == NULL ) { KdPrint((DRIVERNAME " (PDO) - HandleQueryRequirements: STATUS_INSUFFICIENT_RESOURCES\n")); return STATUS_INSUFFICIENT_RESOURCES; } RtlZeroMemory( resourceList, resourceListSize ); resourceList->Count = 1; frd = &resourceList->List[0]; frd->PartialResourceList.Count = 1; // // Get pointer to first Partial Resource // Descriptor in this FRD. // prd = &frd->PartialResourceList.PartialDescriptors[0]; prd->Type = CmResourceTypeInterrupt; prd->ShareDisposition = CmResourceShareShared; prd->Flags = CM_RESOURCE_INTERRUPT_LEVEL_SENSITIVE; prd->u.Interrupt.Level = 3; prd->u.Interrupt.Vector = 64; prd->u.Interrupt.Affinity = -1; Irp->IoStatus.Information = (ULONG_PTR)resourceList; KdPrint((DRIVERNAME " (PDO) - HandleQueryRequirements: STATUS_SUCCESS\n")); return STATUS_SUCCESS; } But IRP_MN_START device in my function driver doesn't get any resources(either translated or raw). Can anybody explain me haw handle this IRP correctly? And please anybody explain to newbie meaning of Interrupt.Level, Interrupt.Vector fields? How should I implement IRP_MN_QUERY_RESOURCE_REQUIREMENTS handling function? Best Darek Tag: sharing memory user mode & virtual video capture driver Tag: 70724

 - Converting Win2k monolithic printer driver to a Longhorn driver - Installation problems Converting Win2k monolithic printer driver to Longhorn driver - INSTALLATION Problems.. The current monolithic(not using Microsoft Universal Printer Driver Model) Windows printer driver has been converted to "user-mode" and installs/runs fine on Win2k, WinXP, and WinServer2003. However, for "Longhorn Beta1" the following error message is given during an attempt to install the driver: Error Message: "The driver that you are trying to install is not compatible with Windows Server 2003 family. Please contact the manufacturer for an updated version." It appears (according to the following windows log files: setupapi.app.log, setupapi.dev.log) that the installation (via the Add Printer Wizard) successfully copies the driver files to a system location, but immediately after that point, the error occurs and the installation is cancelled. I suspect that when the "loader" attempts to load a driver DLL (toward end of installation), it cannot resolve a reference in the DLL to some Win API function (NOT IN Longhorn), and therefore the DLL is not loaded. Normally, one would get some kind of error message that indicates a particular function could not be found/resolved; but this may not be the case while using the "Add Printer Wizard". I placed calls to "MessageBox(-)" at several "entry-point" functions in the DLLs (like DllMain, DLLInitialize, WinMain, DrvQueryDriverInfo, etc.) but these are NOT reached during installation on "Longhorn"; however, they are reached during installation on the other OS's. Any Ideas? Rudy Tag: sharing memory user mode & virtual video capture driver Tag: 70716

 - USB Problem when using a Philips ISP1521 based hub We are using a TI TUSB3410 USB to Serial chip and recently identified an issue when using this device with a Philips based ISP1521 based Hub. On the USB-IF Developers Discussion Forum a post was made that matches our problem exactly. This post also has a statement that Philips apparently made which states the issue is that the Windows USB host controller driver. Basically Philips states that the host controller driver is not terminating Start Split transactions with a Complete Split transaction. For the original posting see http://www.usb.org/phpbb/viewtopic.php?t=6636&highlight=tusb3410&sid=92ad332153ccee7ed3babd646910e98d. We have been told by TI that Microsoft acknowledges that this is a bug and that it will be fixed in Vista. However in the meantime our customers are experiencing problems when using our hardware with ISP1521 based hubs. My question is, how can we work around this issue? Is there something we can do in our application or in the driver to cause the host controller driver to terminate the split transaction? Thanks in advance for any help in resolving this issue. - Steve - Tag: sharing memory user mode & virtual video capture driver Tag: 70696

 - Several problems building the DDK USB-Drivers Examples under W2k BE Hello folks, I beg you to forgive my very little skills in developing drivers. So I'll report my problems right from the start and how I tried to solve 'em. I'm about to develop a USB-driver that implements Bulk-, Interrupt-, Isochronous Transfers. Getting things started, I intended to build the isochronous USB-Drivers from the latest DDKs (3790 & 3790.1830) and communicate with the self-developed device. I'm working on a x86, W2K plattform and because of upward-compatibility on a x86 XP. On both platforms I got the warning, that the existing sample would not be valid for the current OS target. I changed the makefile in looking after a platform >= 0x500, i.e. Win 2k. But problems went on. While the Windows Server 2003 BE builded the driver reliably, the Win2k BE brings up an error C1083: Cannot open include file 'usbbusif.h'. BUILD: Compile errors: not linking c:\usb\sys directory. I looked after the .h file and it appears in %WINDDK%\3790\inc\ddk\wdm\wnet and ...\wxp but not in the adequate w2k-dir. I copied the missing file(s) in ...\w2k but in the aftermath over 700, mostly syntactic errors occured while compiling. The syntax is correct. This sounds clear to me 'cos WNET-Build works fine. I restored the original dirs of the inc\ddk\wdm... I followed some tips in the newsgroup. Although I have no spaces in between dir- or file-names the error still occurs. I have no errors in compiling the test-programs to the usb-drivers of the ddk. I've consulted the DDK-docs, the newsgroups and Walter Oney's 'Programming the WDM 2nd ed.', but none could take me on the fast lane. Now YOU are my only help and I appreciate that very much.

 - Does IPMI driver support BT interface Hello, Our BMC provides both BT & KCS interfaces to the host. I have following questions in regards to Windows IPMI driver: 1. Does it support BT interface? I only see reference to KCS interface support in the documentation. 2. If it does support BT interface, can an application specify an interface (whether KCS or BT) for sending a command to BMC? 3. Can IPMI driver accept simultaneous commands from multiple callers and internally serialize these commands & responses?Does driver allow an application to register to receive IPMI commands from BMC and get event notification once such a command arrives from BMC? (Opposite of normal behavior, apps/Host send the IPMI commands to BMC). Linux OpenIPMI driver allows doing so. I will sincerely appreciate any help on these questions.

It is the call "MmGetSystemAddressForMdl(Irp->MdlAddress)" that fails. It seems that there is a limitation around 65-67mb. The following setup fails : total packages = 16578 bandwith = 4096 buffers = 15 I guess that the system either won't allow me to allocate that amount of memory, or there isn't enough memory left. Any ideas about what could be wrong ?? Thank you in advance. BR Peter Tag: sharing memory user mode & virtual video capture driver Tag: 70646

 - Suspend / Hibernate for PCMCIA device Hi all, I am writing driver for 16-bit PC-Card (PCMCIA) device for Windows XP, and currently facing an issue with Hibernate and suspend. When the machine gets Suspend/Hibernate state, the PCMCIA bus turns off our deviceâ??s power. If I set an error code for IRP_MN_QUERY_POWER, then the OS does not get into both states. (Pop up the dialog which informs our driver rejects the mode). I would like to get the OS to Suspend/Hibernate state and start using hardware when the machine wakes up. Does anyone know the way to keep PCMCIA deviceâ??s power during both modes? Our device is Multi-function PCMCIA device, so the base address should be re-written to the hardware once it turned on, PS: The returned value of QUERY_CAPABILIES from PCMCIA driver says that PowerStateSpleeping1-3, and PowerStateHibernate are mapped to PowerDeviceD3. Thanks in advance. Tag: sharing memory user mode & virtual video capture driver Tag: 70636

 - NDIS IM and hidden proxy Hello, All! I my NDIS IM driver I am trying to redirect all TCP traffic to localhost. To do so, I am changing packet payload (TCP and IP headers). Of cause, I update checksum of IP and TCP packets. Seems like packets do not go throgh. Is there anything else I forgot to do? Do I need to use different miniport handle when sending packets? Currently I am using the same one packed arrived to. How can I get localhost miniport handle?... I tried to redirect packets to both 127.0.0.1 and IP address of my NIC... No luck. Any thoughts would be appreciated. With best regards, serge Tag: sharing memory user mode & virtual video capture driver Tag: 70634

 - Creating an installer for a mirror driver Hi, I'm fairly new to driver development, so apologies if this is rather basic, or has been asked and answered many times before. I have a mirror driver that I want to create an installer for. I tried using DPInst, but it didn't add the driver to the Device Manager's list, so I would still have to use the "Add Hardware" wizard. Is it possible to create an installer for a mirror driver that will eliminate the need to use the "Add Hardware" wizard, and if so, could someone please point me in the right direction for how to do it? Everything I've found so far relates to drivers for new hardware, so doesn't seem like it will work for a mirror driver. Many thanks, Frances Tag: sharing memory user mode & virtual video capture driver Tag: 70633

 - Can't set device interface registry data under W2K... Hi, I have a driver which uses IoOpenDeviceInterfaceRegistryKey() to open a device interface registry key and then uses ZwSetKeyValue() to write values to that key. The driver was originally written for and runs fine under XP. But under W2K, calls to ZwSetKeyValue() fail with 0xC0000008 (STATUS_INVALID_HANDLE) even though the IoOpenDeviceInterfaceRegistryKey() that preceeds it returns STATUS_SUCCESS. Any ideas? Ade.

 - custom keyboard driver I'm porting a software package from Win98 to WinXP embedded. The software runs only on special (custombuild) PC-Hardware. My problem is now that I have a special keyboard (connected to a custom parallel)where I have to read the scan and return lines cyclic and generate the keyboard input for windows. With Win98 I did this by programming the RTC to generate interrupts ~every 4ms on IRQ 8, virtualized in VPICD and unmasked it in the VPICD. In WinXP I didn't find a why to install my own ISR for IRQ 8! Is it possible to do so?? Or do I have to build a cyclic timer (KeSetTimer and so on). Does anyone knows a good code sample for polling every 5ms some hardware ports? bcp Tag: sharing memory user mode & virtual video capture driver Tag: 70607

 - Movie Maker and SRB_GET_DATA_INTERSECTION Hi, I am developing stream class mini driver for windows XP. We want the driver to work with Movie maker. We tested our driver with Ulead and DVapp and it works with both of the applications. But with Movie Maker, I see lots of SRB_GET_DATA_INTERSECTION requests from Stream class driver before the DVcapture stream is opened. Once the stream is opened, we again start seeeing SRB_GET_DATA_INTERSECTION requests, and this is where Movie maker gives "Unknown error ocurred" after some time. I have been trying to figure out what could be the problem for the multiple SRB_GET_DATA_INTERSECTION request but till now I had no luck. Is any one aware of any particular format that Movie maker is expecting from the driver to support. If DVApp and Movie Maker both use MSDV, then what is that Movie is expecting from the driver which DVapp does not. I am using Movie Maker 2.1 with Sony Camcorder. I have even tried Movie maker with both NTSC and PAL camcorders, but no luck. I still see the same behaviour. -Shiv Tag: sharing memory user mode & virtual video capture driver Tag: 70596

 - DrvConvertDevMode - CDM_DRIVER_DEFAULT Hi I don't have a problem, but I'd like to understand this. If the 'DrvConvertDevMode' of my printer driver get's the CDM_DRIVER_DEFAULT value, it should return the driver's default values... now, let's assume that I've a printer driver that can handle 2 types of printers. One is a A4 and the other one a A2 printer (that's the most significant difference). When the driver is called, the printer name passed to it, is not a printer name, but something like this "manufacturer drivername". So, my driver has no chance to find out, if windows want's the informations about the A4 or the A2 printer. So, it can't insert the correct data about papersize, resolution etc. ... could this be a problem? Does Windows ever use the data received by this call? I don't think so... I think, that Windows never uses the CDM_DRIVER_DEFAULT values... am I right? Or do I have to solve this problem? What, if the printer is attached to the network and I can't return correct values, if I can't communicate with it? (so, then it's impossible to say something about standard values, if I don't have the printers name)... thanks MR Tag: sharing memory user mode & virtual video capture driver Tag: 70593

 - DDK Build Environments Hi Folks, it's me again. Well, I have a checked build of my driver for 2003/x86. So now I want to build a version for the other OS's/platforms. Building 2003/ia64 and 2003/amd64 was a snap thanks to the build environment. But when I try to build for XP or 2000, I get the message , "The sample... ... is not valid for the current OS target." I tracked it down to the makefile in the source directory from the sample CDROM I started with. It just dumps this message and quits. Why is this? It just quits if _NT_TARGET_VERSION is less than 0x502 (2003 Server). Will the x86 version of 2003 server driver work under XP or 2000? If so, why a separate build environment. If not, how do I get my driver (derived from storage/class/CDROM ) to build under the older environments? Any help or direction is appreciated.

 - Wi-Fi AP selection by BSSID My NDIS IM driver is offering Wi-Fi services to a user-mode application, through IOCTL calls (the driver generates NdisRequest calls to its bound adapter). Currently, a typical association proceeds as follows (and it works quite well): OID_802_11_INFRASTRUCTURE_MODE OID_802_11_AUTHENTICATION_MODE OID_802_11_ADD_WEP (if needed) OID_802_11_WEP_STATUS OID_802_11_BSSID OID_802_11_SSID I have, however, run across an issue when faced with multiple access points using the same SSID. I was under the impression (after reading the DDK docs over and over) that an OID_802_11_SSID request would establish the association AND that it would use the currently set BSSID value to further restrict its AP selection. On both adapters I tested with (a lousy DLink DWL-122 USB gizmo and a reliable Cisco Aironet 350 PCMCIA card) the behavior seemed erratic - the DLink seemed to ignore my BSSID setting and just picked the AP with the higher RSSI, and the Cisco apparently did something similar (I couldn't do more extensive tests with it yet). Am I doing something wrong or just plain missing a step? Sample association that doesn't always behind to the desired BSSID: - OID_802_11_INFRASTRUCTURE_MODE: Ndis802_11Infrastructure - OID_802_11_AUTHENTICATION_MODE Ndis802_11AuthModeOpen - OID_802_11_WEP_STATUS Ndis802_11WEPDisabled - OID_802_11_BSSID 01:02:03:04:05:06 (desired AP's BSSID) - OID_802_11_SSID "MultipleAPName" --- Benoît Bousquet Tag: sharing memory user mode & virtual video capture driver Tag: 70564

 - Q) PCI Expansion ROM for a CardBus. Subject : Question about PCI Expansion ROM for a CardBus. Dear all, I¡¯m developing NDIS CardBus device driver at Win2K/Xp. It will use PCI Expansion ROM for CardBus CIS only. Q1) What kinds of resource type will I get after using NdisMQueryAdapterResources? I found that CmResourceTypeInterrupt, CmResourceTypeMemory, and etc were defined in ndis.h. But, there is no type for an expansion ROM. Will it be treated as a memory(CmResourceTypeMemory) type? Q2) Are there any side effects to BIOS or bus/bridge drivers that were from Win2K/Xp because of PCI Expansion ROM? My expansion ROM¡¯s content is completely empty except the CardBus CIS information.

 - DeviceIoControl returns no data (WinCE 4.2) All.. we are trying to run a dll almost exaclty same as sample NDISUIO protocol driver on an actual Win CE 4.2 OS based device. we have created a GUI that talks to this driver... here is the issue, Our GUI can send DeviceIOControl call to NDISUIO.dll and receive the binding information. But when we create an exact framework of NDISUIO.dll and call it MYDriver.dll then when GUI sends DeviceIOControl then it actually returns "No Data Available". (I belive the return code is 259) we have checked all the registry key, index and everything with all the correct name... GUI returns OK after OPen and Create... so it seems that it is able to load the MYDriver.dll correctly but not the rest... Any idea what could be the problem or what we are missing here?? we also tried by disabling the running NDISUIO.dll on the wince and have only MYDriver.dll but yet the same issue... thank you in advance for your feedback.

 - How to access 64-bit intrinsic functions? I am trying to create a 64-bit version of a C++ program that includes _asm instructions. The 64-bit C++ compiler does not support assembler. The assembly code apparently can be replaced by a call to one of the intrinsic routines (__readfsdword). However, I am having difficulty finding the magic combination of flags, defines, and switches to make these symbols visible. I have a simple test program (source below) that just prints the return values from these intrinsics, so I can figure out best how to map from the assembly to the intrinsic. No matter what I do, I get "C3861 identifier not found" messages for the intrinsic function calls. I am running Microsoft Visual C++ .net Standard Edition (C/C++ version 14.00.40310.41) against the Platform SDK 2003 SP1. My build environment is established with the Platform SDK's "SetEnv.cmd" file (I've tried various combinations of switches, i.e., "<path>\Setenv.cmd /XP64 /RETAIL". My compiler switches have also varied but are typically something like "cl -c -EHsc /Wp64 -DBITS=64 -DCONSOLE -D_WIN32_WINNT=0x0501 testfile.cpp What must I do to access the 64-bit intrinsic functions?

It would probably be easier to write a DirectShow source filter. That way,
you avoid kernel mode altogether.
