View the official Windows Driver Kit DDI referenceNo description available.
The IoForwardIrpSynchronously routine sends an IRP to a specified driver and waits for that driver to complete the IRP.
DeviceObject [in]Specifies the device object of the driver to which the IRP is sent.
Irp [in]Specifies the IRP to send.
IoForwardIrpSynchronously returns TRUE if the IRP is sent successfully. Otherwise, it returns FALSE.
Use the IoForwardIrpSynchronously routine to synchronously forward the current IRP to the next driver in the stack. (To asynchronously forward the IRP, use the IoCopyCurrentIrpStackLocationToNext, IoCallDriver, and IoSetCompletionRoutine routines.)
The IoForwardIrpSynchronously routine copies the current stack location to the next stack location. That stack location is then used as the current stack location by the driver specified in DeviceObject. If no next stack location is available, the routine returns FALSE. If the routine returns TRUE, then the IRP has been sent to the specified driver, and that driver has completed its processing of this IRP.
