IoUninitializeWorkItem function (wdm.h)

  • Article

The IoUninitializeWorkItem routine uninitializes a work item that was initialized by IoInitializeWorkItem.

Syntax

void IoUninitializeWorkItem(
  [in] PIO_WORKITEM IoWorkItem
);

Parameters

[in] IoWorkItem

Pointer to the IO_WORKITEM structure to uninitialize.

Return value

None

Remarks

Only uninitialize a work item that is not currently queued. The system dequeues a work item before it runs the work item's callback routine, so IoUninitializeWorkItem can be called from within the WorkItem or WorkItemEx routine for the work item.

For more information about work items, see System Worker Threads.
