QUEUE Struct Reference

A QUEUE object A QUEUE object is an object which can be used to queue IRPs for processing. This QUEUE object is optimized for being polled from an own worker thread. Anyway, a concept called FastStart is also implemented, which allows some IRPs to be completed immediately, without being queued, if no IRP is executed yet and the caller has stated that he wants this IRP to be started fast if possible.

Data Fields
IO_CSQ	IrpQueue
	the structure for the cancel-safe queue
LIST_ENTRY	IrpListHead
	the list head for the IRP list

	the spin lock to protect the IRP list
KEVENT	NotEmptyEvent
