The IoGetNextIrpStackLocation routine gives a higher level driver access to the next-lower driver's I/O stack location in an IRP so the caller can set it up for the lower driver.
__drv_aliasesMem PIO_STACK_LOCATION IoGetNextIrpStackLocation( PIRP Irp );
A pointer to the IRP.
IoGetNextIrpStackLocation returns a pointer to the next-lower-level driver's I/O stack location in the given IRP.
Each driver that passes IRPs on to lower drivers must set up the stack location for the next lower driver. A driver calls IoGetNextIrpStackLocation to get a pointer to the next-lower driver's I/O stack location.
If a driver is passing the same parameters that it received to the next-lower driver, it should call IoCopyCurrentIrpStackLocationToNext or IoSkipCurrentIrpStackLocation instead of getting a pointer to the next-lower stack location and copying the parameters manually.
