X Standards

SYNOPSIS

The major goal  of  the  MIT  X  Consortium  is  to  promote
cooperation  within the computer industry in the creation of
standard software interfaces at all layers in the  X  Window
System  environment.   The  status  of various standards and
proposed standards, and of the software in the X11R4 distri-
bution, is explained below.

STANDARDS

The following documents are MIT X Consortium standards:

X Window System Protocol
X Version 11, Release 4
Robert W. Scheifler

Xlib - C Language X Interface
X Version 11, Release 4
James Gettys, Robert W. Scheifler, Ron Newman

X Toolkit Intrinsics - C Language Interface
X Version 11, Release 4
Joel McCormack, Paul Asente, Ralph R. Swick

Bitmap Distribution Format
Version 2.1

Inter-Client Communication Conventions Manual
Version 1.0
David S. H. Rosenthal

Compound Text Encoding
Version 1.1
Robert W. Scheifler

X Logical Font Description Conventions
Version 1.3
Jim Flowers

X Display Manager Control Protocol

DRAFT STANDARDS

The following documents are draft standards of the MIT X Consortium. To become standards, further ``proof of concept'' is required, in the form of working implementations. The specifications may be subject to incompatible changes if implementation efforts uncover significant problems.

PEX Protocol Specification
Version 4.0P
Randi J. Rost (editor)

Extending X for Double-Buffering, Multi-Buffering, and Stereo
Version 3.2
Jeffrey Friedberg, Larry Seiler, Jeff Vroom

PUBLIC REVIEW DRAFTS

The following documents are out for Public Review for adoption as MIT X Consortium standards.

X11 Input Extension Protocol Specification
Public Review Draft
George Sachs, Mark Patrick

X11 Input Extension Library Specification
Public Review Draft
Mark Patrick, George Sachs

INCLUDE FILES

The following include files are part of the Xlib standard. The C++ support in these header files is experimental, and is not yet part of the standard.

<X11/X.h>
<X11/Xatom.h>
<X11/Xproto.h>
<X11/Xprotostr.h>
<X11/keysym.h>
<X11/keysymdef.h>
<X11/Xlib.h>
<X11/Xresource.h>
<X11/Xutil.h>
<X11/cursorfont.h>
<X11/X10.h>
<X11/Xlibint.h>

The following include  files  are  part  of  the  X  Toolkit
Intrinsics  standard.  The C++ support in these header files
is experimental, and is not yet part of the standard.

<X11/Composite.h>
<X11/CompositeP.h>
<X11/ConstrainP.h>

<X11/Constraint.h>
<X11/Core.h>
<X11/CoreP.h>
<X11/Intrinsic.h>
<X11/IntrinsicP.h>
<X11/Object.h>
<X11/ObjectP.h>
<X11/Quarks.h>
<X11/RectObj.h>
<X11/RectObjP.h>
<X11/Shell.h>
<X11/ShellP.h>
<X11/StringDefs.h>
<X11/Vendor.h>
<X11/VendorP.h>

The following include file is part of the Nonrectangular Window Shape Extension standard.

<X11/extensions/shape.h>

The following include file is part of the Multi-Buffering draft standard.

<X11/extensions/multibuf.h>

NON STANDARDS

The X11R4 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.

At the public release of X11R4, the only MIT X Consortium standards are the ones listed above. No other documents, include files, or software in X11R4 carry special status within the X Consortium. For example, none of the following are standards: internal interfaces of the sample server; the MIT-SHM extension; the Input Synthesis extension; the Athena Widget Set; the Xmu library; the Xau library; CLX, the Common Lisp interface to X (although a Consortium review is finally expected to begin); the RGB database; the fonts distributed with X11R4; the applications distributed with X11R4; the include files <X11/XWDFile.h> and <X11/Xos.h>; the bitmap files in <X11/bitmaps>.
