5: * This header deals in removing macro definitions of functions in order to
6: * enhance the portablity of user driver binaries by removing dependencies
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.
12: *
13: * Of course, many DDI/DKI functions exists to remove other dependences, such
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.
21: *
22: * Clients of this header *should* be using the new DDI/DKI functions so as
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.
