NAME
     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.

     tions.   The  specifications  may be subject to incompatible
     changes if implementation efforts uncover significant  prob-
     lems.

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/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.

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

     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>.
