CreateFile "Incorrect Function"

NTDEV

Hi all,

Has anyone run into an error message (GetLastError()) of “Incorrect
Function” when doing a CreateFile using a GUID?

i.e. the code looks like this:

hDevice = CreateFile (
detail->DevicePath,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL);

where:
PSP_DEVICE_INTERFACE_DETAIL_DATA detail;

The path data sent back looked good:

\?\pci#ven_10ee&dev_8382&subsys_838210ee&rev_01#5&1c178e18&0&28f810#{86490f
eb-e578-4a67-8723-674d07363ec2}

The error message doesn’t make sense to my. Anyone have any ideas?

Thanks,

Howard Keller
