  [in, out] __drv_aliasesMem PSINGLE_LIST_ENTRY Entry
);

Parameters

Pointer to the SINGLE_LIST_ENTRY structure that serves as the list header.

[in, out] Entry

Remarks

PushEntryList sets ListHead->Next to Entry, and Entry->Next to point to the old first entry of the list.

For information about using this routine when implementing a singly linked list, see Singly and Doubly Linked Lists.

Callers of PushEntryList can be running at any IRQL. If PushEntryList is called at IRQL >= DISPATCH_LEVEL, the storage for ListHead and the list entries must be resident.
