The ExInterlockedFlushSList routine atomically removes all entries from a sequenced singly linked list.
void ExInterlockedFlushSList( Head );
ExInterlockedFlushSList does not delete the SLIST_ENTRY structures that made up the list; it only sets the internal pointer of ListHead to the beginning of the list to NULL. The driver must free the entries explicitly.
The routine returns a pointer to the first SLIST_ENTRY structure that was on the list. The driver can use this pointer to iterate through the entries.
For more information about using this routine to implement a sequenced singly linked list, see Singly and Doubly Linked Lists.
Callers of ExInterlockedFlushSList can be running at any IRQL. The storage for the ListHead parameter and the list entries must be resident at all IRQLs.
