Article
03/15/2022

The KsForwardIrp function forwards an IRP to the specified driver after initializing the next stack location and setting the file object.

Syntax

KSDDKAPI NTSTATUS KsForwardIrp(
  [in] PIRP         Irp,
  [in] PFILE_OBJECT FileObject,
  [in] BOOLEAN      ReuseStackLocation
);

Parameters

[in] Irp

Specifies the IRP that is being forwarded to the specified driver.

[in] FileObject

Specifies the file object to initialize the next stack with.

[in] ReuseStackLocation

Specifies the new stack location.

Return value

The KsForwardIrp function returns the result of the IoCallDriver, or it returns an invalid status if no more stack depth is available.

Remarks

Use the KsForwardIrp function when only the FileObject parameter of the forwarded IRP changes when the current stack parameters are copied to the next stack location. The function verifies that there is a new stack location to copy into before attempting to copy. If there is no new stack location, the IRP is completed with STATUS_INVALID_DEVICE_REQUEST.
