I need to send a IOCTL to a specific driver. I’m trying to use the ZwOpenFile() + ZwDeviceIoControlFile(), but I’m having trouble in the driver name (I’m using the “??\ServiceName”).
If this is your driver use the symbolic link name the driver created.
If it is not your driver get the OSR utility DeviceTree
http://www.osronline.com/article.cfm?article=97 and find the name.

And precisely what have you tried? “\\.\servicename”? Did you escape the "" in your first attempt such that it looked like “\??\servicename” in your source?
Is this your drivers? If so have you considered a interface between the two drivers, and attaching one driver to another? That way you can ignore the ZwXxxx calls and simply call your interface function.

The driver is mine, but I can’t found a name (in the devicetree) that open the driver. Where do I find this symbolic link?
Yes, I tried to use \??\servicename, but it did not work. I did not understand how I can make this interface, and this communication must be during system boot.
ps: My drivers are a upper disk filter and a SCSIAdapter (virtual disk)
Uh … it’s your driver and you DON’T know the driver name? If you created a symbolic name it should be in front of you in your own source. Did you create a symbolic name? Unless you got really silly in naming your driver, that is IF you named it, it’s usually the name of the SYS file.

I know the driver name, but I do not understand why I can not open using “\??\serviceName”. I tested with other drivers that I have here, and it works.
Do you create a symbolic name for the driver using WdfDeviceCreateSymbolicLink? How about IoCreateSymbolicLink?

With the symbolic link, I can open with ZwOpenFile, but when I send the
IOCTL, ZwDeviceIoControlFile returns ERROR.
The definition of IOCTL is correct?
*#define IOCTL_VDBUS_LOCALCACHE *
* CTL_CODE(FILE_DEVICE_UNKNOWN, 0x208 , METHOD_BUFFERED, FILE_READ_DATA |
FILE_WRITE_DATA)*
*

Because of some reason I don’t know, I can’t send the IOCTL to the miniport using ZwDeviceIoControlFile. So I sent down using IoBuildDeviceIoControlRequest, and it worked perfectly
Many thanks…
