Routine Description:
|
|
|
|
This routine interfaces to the NT Object Manager. It is invoked when
|
|
a Key object (or Key Root object) is closed.
|
|
|
|
It's function is to do cleanup processing by waking up any notifies
|
|
pending on the handle. This keeps the key object from hanging around
|
|
forever because a synchronous notify is stuck on it somewhere.
|
|
|
|
All other cleanup, in particular, the freeing of storage, will be
|
|
done in CmpDeleteKeyObject.
|
|
|
|
Arguments:
|
|
|
|
Process - ignored
|
|
|
|
Object - supplies a pointer to a KeyRoot or Key, thus -> KEY_BODY.
|
|
|
|
GrantedAccess, ProcessHandleCount, SystemHandleCount - ignored
|
|
|
|
Return Value:
|
|
|
|
NONE.
