        !             7:  * on many system definitions such as structure lengths. Since many simple
        !             8:  * functions are implemented as macros to remove the source-level dependency
        !             9:  * while keeping performance, inclusion of the <sys/ddi.h> header indicates
        !            10:  * that the user wishes to make trade off speed and time against binary
        !            11:  * portability.

        !            14:  * as on the size and offsets of structure *members*, and on the names and
        !            15:  * locations of data items. However, this header does not deal with defining
        !            16:  * prototype or anything else related to these aspects of the DDI/DKI
        !            17:  * specification, as they either involve changing source code to use these
        !            18:  * new functions or are old functions (defined in the headers related to the
        !            19:  * subsystem they were appropriated from) that have been elevated to DDI/DKI
        !            20:  * preferred status.

        !            23:  * to reduce dependency on system data structure layout, but here we deal
        !            24:  * with the simple transformation of macros to function calls, by subsystem.
