StorPortInterlockedPushEntrySList function (storport.h)
Inserts an item at the front of a Storport managed singly linked list. Access to the list is synchronized on a multiprocessor system.
Syntax
ULONG StorPortInterlockedPushEntrySList(
[in] PVOID HwDeviceExtension,
[in, out] PSTOR_SLIST_HEADER SListHead,
[in, out] __drv_aliasesMem PSTOR_SLIST_ENTRY SListEntry,
[out] PSTOR_SLIST_ENTRY *Result
);
Parameters
[in] HwDeviceExtension
A pointer to the hardware device extension for the host bus adapter (HBA).
[in, out] SListHead
A pointer to an STOR_SLIST_HEADER structure that represents the head of a singly linked list. This structure is considered opaque and is for use by the Storport driver only.
[in, out] SListEntry
A pointer to an STOR_SLIST_ENTRY structure that represents the item to insert into the singly linked list.
[out] Result
A pointer to a list entry pointer. The value returned is a pointer to the previous item that existed at the front of the list. This previous item remains in the list behind the item new item added from SListEntry. If the list is empty, then NULL is returned in value pointed to by Result.
Return value
StorPortInterlockedPushEntrySList returns one of the following status codes:
| Return code | Description |
|---|---|

|
The list item was successfully inserted into the list or is already empty. |
|
A pointer in SListHead, SListEntry, or Result is NULL. |
Remarks
When allocated by the caller, the STOR_SLIST_ENTRY structure pointed to by SListEntry must be aligned at a MEMORY_ALLOCATION_ALIGNMENT boundary. MEMORY_ALLOCATION_ALIGNMENT is defined in miniport.h.
