Can I check the status of an IRP?

Is there any way that I can know of the status of a given IRP? For example,
is it completed or canceled?

Thanks

There are some structures in an Irp to flag the status,
why don’t you look up the definition of IRP in DDK or MSDN?
I think you can find answer:)
good luck:)

If this is while debugging and you are using WinDbg - the !irp extension
displays information about an IRP.

Simple rule … if you can deref an IRP (IRP->Cancel), and not crash the
system, it ain’t completed. If you expect to do something with an IRP after
you return from your dispatch routine, you MUST set a completion or cancel
routine. You always check for Cancel when you get an IRP or look at an IRP.
When your cancel or completion routine is called, the IRP may be in the
process of being completed but it has not been deallocated.
