int ddi_no_info(dev_info_t *dip, ddi_info_cmd_t infocmd, void *arg,
void **result
illumos DDI specific (illumos DDI)
dev_info_t *dip
Pointer to dev_info structure.
ddi_info_cmd_t infocmd
Command argument. Valid command values are:
DDI_INFO_DEVT2DEVINFO and
DDI_INFO_DEVT2INSTANCE.
void *arg
Command-specific argument.
void **result
Pointer to where the requested information
is stored.
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.

DESCRIPTION
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.
RETURN VALUES
The ddi_no_info() function always returns DDI_FAILURE.
