IO_CSQ_IRP_CONTEXT

The IO_CSQ_IRP_CONTEXT structure is an opaque data structure used to specify the IRP context for an IRP in the driver's cancel-safe IRP queue. It is used as a key by the IoCsqInsertIrp, IoCsqInsertIrpEx, and IoCsqRemoveIrp routines to identify particular IRPs in the queue.

For an overview of how to use cancel-safe IRP queues, see Cancel-Safe IRP Queues.
