The IoQueueWorkItemEx routine associates a WorkItemEx routine with a work item, and it inserts the work item into a queue for later processing by a system worker thread.
IoWorkItem [in]Pointer to an IO_WORKITEM structure that was allocated by IoAllocateWorkItem or initialized by IoInitializeWorkItem.
WorkerRoutine [in]Pointer to a WorkItemEx routine.
QueueType [in]Specifies a WORK_QUEUE_TYPE value that stipulates the type of system worker thread to handle the work item. Drivers must specify DelayedWorkQueue.
Context [in, optional]Specifies driver-specific information for the work item. The system passes this value as the Context parameter to WorkItemEx.
The IoQueueWorkItemEx routine differs from IoQueueWorkItem in that the WorkerRoutine parameter is a pointer to a WorkItemEx callback routine, which provides the driver with a pointer to the IO_WORKITEM structure for the work item.
For more information about work items, see System Worker Threads.
