NTSTATUS cbm_createopenclose (  IN PDEVICE_OBJECT  Fdo, IN PIRP  Irp )

Services IRPs containing the IRP_MJ_CREATE or IRP_MJ_CLOSE I/O function code. Services IRPs containing the IRP_MJ_CREATE or IRP_MJ_CLOSE I/O function code. Parameters: Fdo  Pointer to a DEVICE_OBJECT structure. This is the device object for the target device, previously created by the driver's AddDevice routine. Irp  Pointer to an IRP structure that describes the requested I/O operation. Returns: If the routine succeeds, it returns STATUS_SUCCESS. Otherwise, it returns one of the error status values. The driver's DriverEntry routine has stored this routine's address in DriverObject->MajorFunction[IRP_MJ_CREATE] and DriverObject->MajorFunction[IRP_MJ_CLOSE]. Generally, all Dispatch routines execute in an arbitrary thread context at IRQL PASSIVE_LEVEL, but there are exceptions. Definition at line 48 of file libcommon/openclose.c. References DBG_ERROR, DBG_IRPPATH_COMPLETE, DBG_IRPPATH_PROCESS, DBG_PREFIX, FUNC_ENTER, PERF_EVENT_CLOSE_QUEUE, PERF_EVENT_OPEN_QUEUE, QueueCompleteIrp(), and QueueStartPacket().

NTSTATUS cbm_execute_close (  IN PDEVICE_EXTENSION  Pdx, IN PIRP  Irp )

Execute IRPs containing the IRP_MJ_CLOSE I/O function code. Executes IRPs containing the IRP_MJ_CLOSE I/O function code. Parameters: Pdx  Pointer to a DEVICE_EXTENSION structure. Irp  Pointer to an IRP structure that describes the requested I/O operation. Returns: If the routine succeeds, it returns STATUS_SUCCESS. Otherwise, it returns one of the error status values. Definition at line 167 of file libcommon/openclose.c.

NTSTATUS cbm_execute_createopen (  IN PDEVICE_EXTENSION  Pdx, IN PIRP  Irp )

Execute IRPs containing the IRP_MJ_CREATEOPEN I/O function code. Executes IRPs containing the IRP_MJ_CREATEOPEN I/O function code. Parameters: Pdx  Pointer to a DEVICE_EXTENSION structure. Irp  Pointer to an IRP structure that describes the requested I/O operation. Returns: If the routine succeeds, it returns STATUS_SUCCESS. Otherwise, it returns one of the error status values.
