Hi,
I am using
LPCWSTR Device = L"\\\\.\\XXXXXXXX";
hFile = CreateFile(Device,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE, NULL,
OPEN_EXISTING, 0, NULL);
For the creation of handle it is working File, Now if i try to create
another handle with
hFile = CreateFile(Device,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE, NULL,
OPEN_EXISTING, 0, NULL);
This is failing with ACCESS_DENIED
what is the problem here? \\\\.\\XXXXXXXX has been created in device driver
sucessfully.
