the mean of "WorkItem"

NTDEV
1

I am a beginner of NDIS Miniport Driver.

When I am learning the knowledge of this field, I can not understand the mean of “WorkItem” which was introduced in NdisInitializeWorkItem and NdisScheduleWorkItem.

Is there anybody could tell me the mean of WorkItem?

Thanks a lot!

A work item is a routine and a context pointer you wish
to have run on one of the system worker threads. Typically, this is done
because you are at DISPATCH_LEVEL
IRQL and need to perform an operation that must run at
less than DISPATCH_LEVEL, for example allocating or
freeing memory. One thing to note on work items, they
should not take a long time, there are a limited number
of worker threads and they are a system wide resource.

Read an MSDN article on IoQueueWorkItem.
