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The Multi-Buffering extension was a draft standard of the X Consortium but has been superseded by DBE as a standard.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