This function is documented in Windows Driver Kit.
The IsListEmpty routine indicates whether a doubly linked list of LIST_ENTRY structures is empty.
ListHead
[in]Pointer to a LIST_ENTRY structure that represents the head of the list.
IsListEmpty returns TRUE if there are currently no entries in the list and FALSE otherwise.
IsListEmpty returns TRUE if ListHead->Flink refers back to ListHead.
For information about using this routine when implementing a doubly linked list, see Singly and Doubly Linked Lists.
Callers of IsListEmpty can be running at any IRQL. If IsListEmpty is called at IRQL >= DISPATCH_LEVEL, the storage for ListHead must be resident.
