Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. Where those designations appear in this book, and O'Reilly & Associates, Inc. was aware of a trademark claim, the designations have been printed in caps or initial caps.

This document is based in part on Xlib---C Language X Interface, by Jin Gettys, Ron Newman, and Robert Scheifer, and the X Window System Protocol, Version 11, by Robert Scheifer and Ron Newman, both of which are copyright © 1985, 1986, 1987, the Massachusetts Institute of Technology, Cambridge, Massachusetts, and Digital Equipment Corporation, Maynard, Massachusetts. In addition, we have included some material provided in Oliver Jones' Xlib Tutorial Overheads, which was distributed at the MIT X Conference in January 1988 and which is copyright © 1987 Apollo Computer, Inc.
