Hi all,
I am trying open the upper class(HDC) filter driver, to send IOCTL request
from user application. getting INVALID_HANDLE_VALUE. with LastError = 1
(ERROR_INVALID_FUNCTION);
The symbolic link is created for the driver.
Any idea? Thanks for your help
hDevice = CreateFile( “\\.\tdfilter”, GENERIC_READ |
GENERIC_WRITE,
0,
NULL,
OPEN_EXISTING,
0,
NULL);
Try this:
HANDLE hDev = CreateFile(
DevicePath,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL
);
Mat

Thanks Mat,
I tried. still have the same problem. Could this be due to symbolic link.
Here is how the symbolic created in Adddevice() routine for first device object.

Do you handle IRP_MJ_CREATE in your driver?
If so, was IRP_MJ_CREATE dispatch routine called when application calls
CreateFile() and what status is returned from the dispatch routine?
Alexei.

Thanks Alexei.
I wasn’t handling IRP_MJ_CREATE in my driver. Now I do. it works.
Regards, Shakeel.
