Hi friends,
Strange problem this time.
I have hooked the NtOpenFileCall.
For every File Getting opened i am creating a event
and waiting on it using the KeWaitForSingleCall.
The problem is that the IoCreateNotificationEvent
call always succeeds, but the event never appears in
the WinObj program.( WinObj program displays all the
event objects currently active in the system)
Also i have a user mode app which tries to openthis
event theu OpenEvent Call.This call always fails ( of
course it will coz the event is not shown by the
WinObj ).
Also one thing to notice is that the
KeWaitForSingleObject waits on the Event properly.
I know that this is strange but has anyone ever come
around this problem.
Please suggest me some pointers as to how to solve the
problem.

Are you looking in BaseNamedObjects? I assume you are using a named event!

Are you placing the event in the Basenamedobjects path? In order for
Win32 to see your named event, it must me like this:
\basenamedobjects\eventname
