The idea of this set of APIs is to not // force a single queue data structure but allow the cancel logic to be hidden // from the drivers. A driver implements a queue and as part of its header // includes the IO_CSQ structure. In its initialization routine it calls // IoInitializeCsq. Then in the dispatch routine when the driver wants to // insert an IRP into the queue it calls IoCsqInsertIrp. When the driver wants // to remove something from the queue it calls IoCsqRemoveIrp. Note that Insert // can fail if the IRP was cancelled in the meantime. Remove can also fail if // the IRP was already cancelled. // // There are typically two modes where drivers queue IRPs. These two modes are // covered by the cancel safe queue API set. // // Mode 1: // One is where the driver queues the IRP and at some later // point in time dequeues an IRP and issues the IO request. // For this mode the driver should use IoCsqInsertIrp and IoCsqRemoveNextIrp. // The driver in this case is expected to pass NULL to the irp context // parameter in IoInsertIrp. // // Mode 2: // In this the driver queues theIRP, issues the IO request (like issuing a DMA // request or writing to a register) and when the IO request completes (either // using a DPC or timer) the driver dequeues the IRP and completes it. For this // mode the driver should use IoCsqInsertIrp and IoCsqRemoveIrp. In this case // the driver should allocate an IRP context and pass it in to IoCsqInsertIrp. // The cancel API code creates an association between the IRP and the context // and thus ensures that when the time comes to remove the IRP it can ascertain // correctly. // // Note that the cancel API set assumes that the field DriverContext[3] is // always available for use and that the driver does not use it. // // // Bookkeeping structure.
