View the official Windows Driver Kit DDI referenceNo description available.
A miniport-provided callback function for processing a Storport work item request.
HwDeviceExtension [in]A pointer to the miniport driver's per-HBA storage area.
Context [in, optional]Optional context provided by the miniport in the Callback parameter of StorPortQueueWorkItem.
Worker [in]A pointer to an opaque buffer that holds context information for the work item returned by StorPortInitializeWorker.
If needed, a work item can be queued within HwStorWorkItem. Call StorPortQueueWorkItem with the current work item to reuse it. Otherwise, call StorPortFreeWorker to release the work item.
No locks are acquired by Storport when the callback is invoked. The miniport is responsible for any synchronization required in the callback routine.
The name HwStorWorkItem is just a placeholder for the miniport function that is pointed to by the Callback parameter of StorPortQueueWorkItem. The actual prototype of this routine is defined in Storport.h as follows:
typedef
VOID
HW_WORKITEM (
_In_ PVOID HwDeviceExtension,
_In_Opt_ PVOID Context,
_In_ PVOID Worker,
);
