DDI function tables This appendix discusses the interfaces provided by the Solaris DDI/DKI. These descriptions should not be considered complete or definitive, nor do they provide a thorough guide to usage. The descriptions are intended to describe what the functions do in general terms. See physio9F for more detailed information.
