#ifndef	__SYS_DDI_H__
#define	__SYS_DDI_H__

/*
 * This header deals in removing macro definitions of functions in order to
 * enhance the portablity of user driver binaries by removing dependencies
 * on many system definitions such as structure lengths. Since many simple
 * functions are implemented as macros to remove the source-level dependency
 * while keeping performance, inclusion of the <sys/ddi.h> header indicates
 * that the user wishes to make trade off speed and time against binary
 * portability.
 *
 * Of course, many DDI/DKI functions exists to remove other dependences, such
 * as on the size and offsets of structure *members*, and on the names and
 * locations of data items. However, this header does not deal with defining
 * prototype or anything else related to these aspects of the DDI/DKI
 * specification, as they either involve changing source code to use these
 * new functions or are old functions (defined in the headers related to the
 * subsystem they were appropriated from) that have been elevated to DDI/DKI
 * preferred status.
 *
 * Clients of this header *should* be using the new DDI/DKI functions so as
 * to reduce dependency on system data structure layout, but here we deal
 * with the simple transformation of macros to function calls, by subsystem.
