.CH "Appendix A: Changes Since Release 3" A
.H 1 Introduction
For each book in the
.SM UNIX
System V Release 4 document set,
this appendix describes the major changes between Release 3 and Release 4.
See the chapter
.CT "Processing the SCP MRD Tape"
for general instructions on how to print the books.
Special instructions for printing specific books are included in this appendix.
.P
For documents whose names end in ``(Manual Pages),''
some of the information in this appendix applies to the guide material for those documents
rather than to the manual pages provided as part of the SCP MRD tape.
.H 1 "BSD/XENIX\(rg Compatibility Guide (Manual Pages)"
This is a new book for Release 4.
It describes the capabilities of BSD, SunOS, and XENIX software
provided in the BSD and XENIX compatibility packages.
This documentation consists mostly of manual pages.
.H 1 "Device Driver Interface/Driver\-Kernel Interface (DDI/DKI) Reference Manual" "DDI/DKI Reference Manual"
This is a new book for Release 4 and is organized as follows:
.BL
.LI
Introduction
.sp 0.5
The Introduction explains, at a high level, what the Device Driver
Interface (DDI) and Driver\(enKernel Interface (DKI) are and how they
differ from other interfaces.  
.P
The Introduction to Section 3 also contains descriptive information on
porting requirements and a kernel function summary table.
.LI
Reference Sections
.sp 0.5
Three alphabetically-arranged reference manual sections provide specific
information (routines, functions and data structures) for driver
writers.
In some cases, code examples are provided to illustrate functionality.
.P
The reference sections are numbered as D2, D3, and D4 and are
summarized as follows:
.BL
.LI
D2\(emDescribes the system entry-point routines that comprise the driver code.
.LI
D3\(emDescribes the kernel functions that are used in DDI/DKI code.
.LI
D4\(emDescribes the kernel data structures that DDI/DKI drivers interface.
.LE
.P
The reference pages are numbered D\f2n\f1D, D\f2n\f1K, and D\f2n\f1DK
and are summarized as follows: 
.BL
.LI
D\f2n\f1D\(emFunctions supported only by the DDI
.LI
D\f2n\f1K\(emFunctions supported only by the DKI
.LI
D\f2n\f1DK\(emFunctions supported by both DDI and DKI
.LE
.LI
Appendix A: Error Codes
.sp 0.5
Lists DDI/DKI error codes.
.LI
Appendix B: Migration from Release 3.2 to Release 4
.sp 0.5
Includes a migration table describing the differences between Release 3.0
Block and Character Interface (BCI) kernel functions and
Release 4 DDI/DKI kernel functions.
.LE
.H 2 "Special Printing Instructions"
The DDI/DKI manual has both guide material and manual pages.
Chapter 1, the chapter 2, 3, and 4 introductions, and the appendixes are guide material.
Chapters 2, 3, and 4 also have manual pages.
.P
If you print the DDI/DKI manual using the standard formatting tools,
the guide material is printed
with pages numbered continuously, with each page
including the chapter number,
and manual pages are printed without chapter numbers and with
each entry numbered beginning with page 1.
.P
You may also print the DDI/DKI manual in a customized form
that allows you to generate a subject index for material in the manual pages.
Reference manuals do not usually have subject indexes, because the
.UI man (5)
macros used in the reference manuals do not include the indexing macro,
.UI \&.IX .
Also, the
.UI format
command does not generate indexing information for reference manuals.
.P
Because there is little tutorial material on DDI/DKI, however,
the DDI/DKI manual pages have indexing macros in them.
You can generate a subject index for the DDI/DKI manual
and print the book in a form appropriate for an index by taking the following steps:
.BL
.LI
Print the guide material (Chapter 1, the appendixes, and the introductions to
chapters 2, 3, and 4) using
.UI format
as usual and save the table-of-contents files, which have information
for the index and for the tables of contents.
.LI
Use
.UI troff
directly to print the manual entries with consecutive page numbering that includes the
chapter number, and capture the standard error output of
.UI troff .
This output contains indexing information and table-of-contents information for the manual entries.
Here is a sample
.UI troff
line that captures the indexing information for the section 2 manual entries:
.DS +0.5i UI
pic $MACROS sect2.man | tbl | \e
	troff -Tpost -rC1 -S2 -p4 2>Csect2.man \f1. . .\fP
.DE
This command line assumes that the environment variable
.UI MACROS
has been set to the name of the file that holds the manual page macros and
that
.UI sect2.man
has the concatenated manual entries for section two.
The
.UI \-rC1
argument to
.UI troff
specifies that the manual pages are to be numbered continuously instead of beginning
each entry with page 1.
The
.UI \-S2
argument specifies that the page numbers are to have section number 2 prepended.
The
.UI \-p4
argument specifies that pages are to be numbered starting with 4.
(The introduction to section 2 takes pages 1 through 3.)
All these command-line options are explained in the
.SM DOCTOOLS
documentation.
The command line finally redirects the
standard error output of
.UI troff
to the file
.UI Csect2.man .
When the command finishes,
.UI Csect2.man
contains indexing information and the page numbers
of the manual entries (for the table of contents).
The example omits postprocessing commands, which depend on local
printer destinations.
.LI
To generate the index, combine the index information from the guide material
and the manual entries and run the index using both.
If you collect indexing information for the manual entries of sections 2, 3, and 4
as in the example above, you can generate the index for the book using the command line:
.DS +0.5i UI
index Csect1.gui \e
	Csect2.gui Csect2.man \e
	Csect3.gui Csect3.man \e
	Csect4.gui Csect4.man \e
	Capp.errors Capp.mig > index
.DE
This command writes the book index to a file named
.UI index .
.LI
To generate chapter tables of contents for chapters 2, 3, and 4,
combine the guide information and the manual entry information:
.DS +0.5i UI
format -d \f2dest\fP Csect2.gui Csect2.man
format -d \f2dest\fP Csect3.gui Csect3.man
format -d \f2dest\fP Csect4.gui Csect4.man

PostScript Language Interpreter while the
.BT "Shapes Porting Guide"
concerns itself just with screen object rendering code and display
device code.
.LI
.BT "Shapes Porting Guide" \(em
This document contains topics to consider when porting Shapes to
devices which are not supported by Shapes code.  The document is
aimed at someone with C programming background who is familiar with the
UNIX environment.  In addition, you should be well-acquainted with
Shapes, especially screen object and low-level rendering.  The
manual discusses the porting process, gives an overview of dispatch
tables, the directory structure, compiling considerations, porting
at the screen object level and testing the port as you go.
.LI
.BT "Shapes Reference Manual"
This manual is a reference to the external operators, attributes,
and macros of the Shapes graphics library.
It is designed to help you understand how the Shapes library is

X11/NeWS provides an integrated environment in which both are
supported.  Both types of applications work off a single window manager.
This guide, which describes the X11/NeWS server and its components, 
explains how to run X11/NeWS applications and explains the window
management facility.  The
manual assumes that you are reasonably familiar with the Adobe
PostScript\(rg language.
This document describes the initialization process and gives
examples about how to modify your own initialization
routine by customizing PostScript files. It also discusses different
ways you can run NeWS programs.  The manual, contains sections
describing X11 utilities
