Syntax
ULONG StorPortQueryDepthSList(
[in] PVOID HwDeviceExtension,
[in, out] PSTOR_SLIST_HEADER SListHead,
[out] PSHORT 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.
[out] Result
A pointer to a SHORT value which receives the list depth count.
Return value
StorPortQueryDepthSList returns one of the following status codes:
| Return code | Description |
|---|---|
|
This function is not implemented on the active operating system. |
|
The list depth was successfully returned. |
|
A pointer in SListHead or Result is NULL. |
Remarks
Since StorPortQueryDepthSList is not interlocked, the list depth value pointed to by Result on return is not reliable in when multiple threads are operating on the list.
