Using named events

NTFSD

Can anyone give me a pointer on how to wait on one of the events
named in the object directory (e.g. SeLsaInitEvent)?

Thanks

I would try ZwOpenEvent() to get a handle and ObReferenceObjectByHandle() to
get a pointer.

Can you tell me where this function is defined? It doesn’t seem to
be in the DDK (NT4 or 2000) and there is no mention of it in the docs
either.

Gary Nebbett’s Windows NT/2000 Native API Reference page 216.

NTSTATUS ZwOpenEvent(OUT PHANDLE EventHandle, IN ACCESS_MASK DesiredAccess,
IN POBJECT_ATTRIBUTES ObjectAttributes);

//
// Event Specific Access Rights.
//

#define EVENT_QUERY_STATE 0x0001
#define EVENT_MODIFY_STATE 0x0002 // winnt
#define EVENT_ALL_ACCESS (STANDARD_RIGHTS_REQUIRED|SYNCHRONIZE|0x3) //
winnt
