DESCRIPTION


The scsi_hba_iport_unit_address() function is used to obtain the unit
address of an iport. For more information on iports, see iport(9).

This function can be used to determine whether or not a device node in the
tree is an iport. If the device node corresponds to an iport, then the
unit address used when it was created either through
scsi_hba_iport_register(9F) or scsi_hba_iportmap_iport_add(9F) will be
returned.

CONTEXT


The scsi_hba_iport_unit_address() function may be called in user, kernel,
or interrupt context.

RETURN VALUES


If dip is an iport, then the unit address string the device was registered
with is returned. Otherwise, NULL is returned.
