Preface

About This Manual

This manual describes the X library, the C Language programming interface to Version 11 of the X Window System. The X library, known as Xlib, is the lowest level of programming interface to X. This library enables a programmer to write applications with an advanced user interface based on windows on the screen, with complete network transparency, that will run without changes on many types of workstations and personal computers.

Xlib is powerful enough to write effective applications without additional programming tools and is necessary for certain tasks even in applications written with higher-level "toolkits."

There are a number of these toolkits for X programming, the most notable being the DEC/MIT toolkit Xt, the Andrew toolkit developed by IBM and Carnegie-Mellon University, and the Interviews toolkit from Stanford. These toolkits are still evolving, and only Xt is currently part of the X standard. Toolkits simplify the process of application writing con siderably, providing a number of widgets that implement menus, command buttons, and other common features of the user interface.

This manual does not describe Xt or any other toolkit. That is done in Volumes Four, Five, and Six of our X Window System series. Nonetheless, much of the material described in this book is helpful for understanding and using the toolkits, since the toolkits themselves are written using Xlib and allow Xlib code to be intermingled with toolkit code.

Summary of Contents

This manual is divided into two volumes. This is the second volume, the Xlib Reference Manual. It includes reference pages for each of the Xlib functions (organized alphabeti cally), a permuted index, and numerous appendices and quick reference aids.

The first volume, the Xlib Programming Manual, provides a conceptual introduction to Xlib, including tutorial material and numerous programming examples. Arranged by task or topic, each chapter brings together a group of Xlib functions, describes the conceptual foundation they are based on, and illustrates how they are most often used in writing applications (or, in the case of the last chapter, in writing window managers). Volume One is structured so as to be useful as a tutorial and also as a task-oriented reference.

Preface

Volume One and Volume Two are designed to be used together. To get the most out of the examples in Volume One, you will need the exact calling sequences of each function from Volume Two. To understand fully how to use each of the functions described in Vol ume Two, all but the most experienced X "hacker" will need the explanation and examples in Volume One.

Both volumes include material from the original Xlib and XI1 Protocol documentation pro vided by MIT, as well as from other documents provided on the MIT release tape. We have done our best to incorporate all of the useful information from the MIT documentation, to correct references we found to be in error, to reorganize and present it in a more useful form, and to supplement it with conceptual material, tutorials, reference aids, and examples. In other words, this manual is not only a replacement but is a superset of the MIT documenta tion.

Those of you familiar with the MIT documentation will recognize that each reference page in Volume Two includes the detailed description of the routine found in Gettys, Newman, and Scheifler's Xlib-C Language X Interface, plus, in many cases, additional text that clarifies ambiguities and describes the context in which the routine would be used. We have also added cross references to related reference pages and to where additional information can be found in Volume One.

How to Use This Manual

Volume Two is designed to make it as easy and fast as possible to look up virtually any fact about Xlib. It includes a permuted index, reference pages for each library function, appen dices that cover macros, structures, function groups, events, fonts, colors, cursors, keysyms, and errors, and at-a-glance tables for the graphics context and window attributes.

The permuted index is the standard UNIX way of finding a particular function name given a keyword. By looking up a word in the second column that you think describes the function you are looking for, you can find the group of functions that have that word in their descrip tion lines. The description line also appears at the top of each reference page. Once you have found the routine you are looking for, you can look for its reference page.

The reference pages themselves provide all the details necessary for calling each routine, including its arguments, returned values, definitions of the structure types of arguments and returned values, and the errors it may generate. Many of the pages also give hints about how the routine is used in the context of other routines. This is the part of this volume you will use the most.

Appendix A, Function Group Summary, groups the routines according to function, and pro vides brief descriptions. You'll find it useful to have in one place a description of related routines, so their differences can be noted and the appropriate one chosen.

Appendix B, Error Messages and Protocol Requests, describes the errors that Xlib routines can generate. When an error is handled by the default error handler, one of these messages is printed. Also printed is the X Protocol request that caused the error. Since Protocol requests do not map directly to Xlib routines, this appendix provides a table with which you can find out which Xlib routine in your code caused the error.

Xlib Reference Manual

Appendix C, Macros, describes the macros that access members of the Display structure, classify keysyms, and convert resource manager types.

Appendix D, ColorCaEE, presents the standard color database. The color names in this data base should be available on all servers, though the corresponding RGB values may have been modified to account for screen variations.

Appendix E, Event Reference, describes each event type and structure, in a reference page format. This is an invaluable reference for event programming.

Appendix F, Structure Reference, describes all structures used by Xlib except the event struc tures described in Appendix E, including which routines use each structure.

Appendix G, Symbol Reference, lists in alphabetical order and describes all of the symbols defined in Xlib include files.

Appendix H, Keysym Reference, lists and describes each character in the standard keysym families, used for translating keyboard events. The characters for English and foreign lan guage keysyms are shown where possible.

Appendix I, The Cursor Font, describes the standard cursor font, including a illustration of the font shapes.

Appendix J, The Xmu Library, provides reference pages for each function in the miscella neous utilities library. This library is provided with the standard X distribution and is very useful when programming with Xlib.

Finally, Volume Two concludes with at-a-glance charts that help in setting the graphics con text (GC) and the window attributes.

Example Programs

The example programs in this book are on the XI1 Release 4 distribution in the contributed section. There are many ways of getting this distribution; most are described in Appendix H.

The example programs are also available free from UUNET (that is, free except for UUNET's usual connect-time charges). If you have access to UUNET, you can retrieve the source code using uucp orftp. For uucp, find a machine with direct access to UUNET and type the follow ing command:

uucp uunet\!~uucp/nutshell/Xlib/xlibprgs.tar.Z yourhosW'/yourname/

The backslashes can be omitted if you use the Bourne shell (sh) instead of csh. The file should appear some time later (up to a day or more) in the directory lusrlspoolluucp-publiclyourname.

To ustftp,ftp to uunet.uu.net and use anonymous as your user name and guest as your pass word. Then type the following:

cd /nutshell/Xlib

binary ( you must specify binary transfer for compressed files)

get xlibprgs.tar.Z

bye

Preface

The file is a compressed tar archive. To restore the files once you have retrieved the archive, type:

uncompress xlibprgs.tar tar xvf xlibprgs.tar

The example programs are also available free by/fp from expo.lcs.mit.edu. The directory containing the examples is contriblexampleslOReillylXlib .

The examples will be installed in subdirectories under the current directory, one for each chapter in the book. Imakefiles are included. (Imakefiles are used with imake, a program supplied with the XI1 distribution that generates proper Makefiles on a wide variety of sys tems.)

Assumptions

Readers should be proficient in the C programming language, although examples are pro vided for infrequently used features of the language that are necessary or useful when pro gramming with X. In addition, general familiarity with the principles of raster graphics will be helpful.

The information contained in this manual is based in part on Xlib-C Language X Interface, written by Jim Gettys, Ron Newman, and Robert Scheifler, and the X Window System Proto col, Version 11, by Robert Scheifler (with many contributors). The X Window System soft ware and these documents were written under the auspices of Project Athena at MIT. In addition, this manual includes material from Oliver Jones' Xlib tutorial presentation, which was given at the MIT X Conference in January 1988, and from David Rosenthal's Inter-Client Communication Conventions Manual.

I would like to thank the people who helped this book come into being. It was Tim O'Reilly who originally sent me out on a contract to write a manual for X Version 10 for a workstation manufacturer and later to another company to write a manual for X Version 11, from which this book began. I have learned most of what I know about computers and technical writing while working for Tim. For this book, he acted as an editor, he helped me reorganize several chapters, he worked on the Color and Managing User Preferences chapters when time was too short for me to do it, and he kept my spirits up through this long project. While I was concentrating on the details, his eye was on the overall presentation, and his efforts improved the book enormously.

This book would not be as good (and we might still be working on it) had it not been for Daniel Gilly. Daniel was my production assistant for critical periods in the project. He dealt with formatting issues, checked for consistent usage of terms and noticed irregularities in content, and edited files from written corrections by me and by others. His job was to take as much of the work off me as possible, and with his technical skill and knowledge of UNIX, he did that very well.

This manual has benefitted from the work and assistance of the entire staff of O'Reilly and Associates, Inc. Susan Willing was responsible for graphics and design, and she proofed many drafts of the book; Linda Mui tailored the troff macros to the design by Sue Willing and myself and was invaluable in the final production process; John Strang figured out the resource manager and wrote the original section on that topic; Karen Cakebread edited a draft of the manual and established some conventions for terms and format. Peter Mui exe cuted the "at-a-glance" tables for the inside back cover; Tom Scanlon entered written edits and performed copy fitting; Donna Woonteiler wrote the index of the book, Valerie Quercia, Tom Van Raalte, and Linda Walsh all contributed in some small ways; and Cathy Brennan, Suzanne Van Hove, and Jill Berlin fielded many calls from people interested in the X manual and saved me all the time that would have taken. Ruth Terry, Lenny Muellner, and Donna

xxii Xlib Reference Manual

Woonteiler produced the Second Edition, with graphics done by Chris Reilly. A special thanks to everyone at O'Reilly and Associates for putting up with my habits of printer and terminal hogging, lugging X books around, recycling paper, and for generally being good at what they do and good-natured to boot.

Many people sent in corrections for this Second Edition of the manual. Those whose efforts were most noteworthy were Jane-Na Chang of NEC, Jonathan Saunders of Identification and Security Systems Inc., Saundra Miller, and Russell Ferriday.

I would also like to thank the people from other companies that reviewed the book or other wise made this project possible: John Posner, Barry Kingsbury, Jeff MacMann and Jeffrey Vroom of Stellar Computer; Oliver Jones of Apollo Computer; Sam Black, Jeff Graber, and Janet Egan of Masscomp; Al Tabayoyon, Paul Shearer, and many others from Tektronix; Robert Scheifler and Jim Fulton of the X Consortium (who helped with the Color and Managing User Preferences chapters), and Peter Winston II and Aub Harden of Integrated Computer Solutions. Despite the efforts of the reviewers and everyone else, any errors that remain are my own.

Preface

Permuted Index

How to Use the Permuted Index

The permuted index takes the brief descriptive string from the title of each command page and rotates (permutes) the string so that each keyword will at one point start the second, or center, column of the line. The beginning and end of the original string are indicated by a slash when they are in other than their original position; if the string is too long, it is trun cated.

To find the command you want, simply scan down the middle of the page, looking for a key word of interest on the right side of the blank gutter. Once you find the keyword you want, you can read (with contortions) the brief description of the command that makes up the entry. If things still look promising, you can look all the way over to the right for the name of the relevant command page.
