The ddi_no_info() function always returns DDI_FAILURE. It is provided as a convenience routine for drivers not providing a cb_ops(9S) or for network drivers only providing DLPI-2 services. Such drivers can use ddi_no_info() in the devo_getinfo entry point (see getinfo(9E)) of the dev_ops(9S) structure.

The ddi_no_info() function always returns DDI_FAILURE.
