NAME

       XStandards - X Window System Standards and Specifications

SYNOPSIS

       The  major  goal  of the X Consortium was to promote cooperation within
       the computer industry in the creation of standard  software  interfaces
       at  all  layers  in  the X Window System environment.  The X Consortium
       produced  standards  -  documents  which  defined  network   protocols,
       programming  interfaces, and other aspects of the X environment.  These
       standards continue to exist in  the  X.Org  Foundation  releases.   The
       X.Org  Foundation  also  produces specifications.  Like X Window System
       Standards,  these  are  documents  which  define   network   protocols,
       programming  interfaces, and other aspects of the X environment.  Under
       the  aegis  of  The  Open  Group,  X  Window  System  standards,  X.Org
       Foundation  specifications,  and other specifications are the basis for
       portions of The Open Group’s various CAE specifications.

       The status of various standards, specifications, and  the  software  in
       the X11R7.0 distribution, is explained below.

NON STANDARDS

       The X11R7.0 distribution contains sample implementations, not reference
       implementations.  Although much of the code is believed to be  correct,
       the  code  should  be assumed to be in error wherever it conflicts with
       the specification.

       The only X Window System standards are the ones listed above.  No other
       documents,  include  files, or software in X11R7.0 carry special status
       within the X Window System.  For example, none  of  the  following  are
       standards:  internal  interfaces  of  the  sample  server;  the MIT-SHM
       extension; the Athena Widget Set; the Xmu library; the Xau library; the
       RGB  database;  the  X  Locale  database;  the  fonts  distributed with
       X11R7.0; the applications distributed with X11R7.0; the  include  files
       <X11/XWDFile.h>,  <X11/Xfuncproto.h>,  <X11/Xfuncs.h>, <X11/Xosdefs.h>,
       <X11/Xos.h>, <X11/Xos_r.h>, <X11/Xwinsock.h>, and <X11/Xthreads.h>; the
       bitmap files in <X11/bitmaps>.

       The  Multi-Buffering extension was a draft standard of the X Consortium
       but has been superseded by DBE as a standard.

X REGISTRY

       The X.Org Foundation maintains a registry of certain  X-related  items,
       to aid in avoiding conflicts and to aid in sharing of such items.

       The  registry  is  published  as  part  of the X Window System software
       release.  The latest version may also be found at
            ftp://ftp.x.org/pub/DOCS/registry
       The X Registry and the names in it are not X Window System standards.
