Hi,
Introduction:
*******************************
I am developing a system consisting of two drivers:
[one] Is fixed and is loaded during the OS boot sequence and [the other] is a dynamically loaded driver ( a function driver ) used to communicate with the fixed driver on one side and to communicate with user-mode on the other side.
The problem:
*******************************
The fixed driver is created with the following name: L"\FileSystem\Filters\ExecGaurd", ( no symbolic-link is created for this driver ).
To establish communication between the two drivers upon startup ( from within the DriverEntry routine ) the dynamic ( function ) driver calls IoGetDeviceObjectPointer(L"\FileSystem\Filters\ExecGaurd", … ), the returned value is 0xC0000034 : STATUS_OBJECT_NAME_NOT_FOUND…
What may cause such a problem?
[A] Must I Create a symbolic link for the fixed driver to be able to communicate with it from within the kernel?
[B] Should I use any special syntax to describe the name of the driver I want to refer to ( something different then L"\FileSystem\Filters\ExecGaurd" ).
Any comment pointer or sample would be appreciated.
Nadav.
