The TmDereferenceEnlistmentKey routine decrements the reference count for the key of a specified enlistment object.
Enlistment [in]A pointer to an enlistment object. Your component can receive this pointer as input to a ResourceManagerNotification callback routine. Alternatively, your component can call ObReferenceObjectByHandle and supply the object handle that a previous call to ZwCreateEnlistment, TmCreateEnlistment, or ZwOpenEnlistment provided.
LastReference [out, optional]A pointer to a BOOLEAN-typed variable. This variable receives TRUE if the reference count is zero after TmDereferenceEnlistmentKey decrements it. Otherwise, the variable receives FALSE.
TmDereferenceEnlistmentKey returns STATUS_SUCCESS if the operation succeeds. Otherwise, this routine might return one of the following values:
| Return code | Description |
|---|---|
| STATUS_UNSUCCESSFUL | The reference count of the specified enlistment object is zero and cannot be decremented. |
The routine might return other NTSTATUS values.
The TmReferenceEnlistmentKey routine increments the reference count for an enlistment object's key, and the TmDereferenceEnlistmentKey routine decrements the count.
