.TH ANSI2KNR 1 "19 Jan 1996"
.SH NAME
ansi2knr \- convert ANSI C to Kernighan & Ritchie C
.SH SYNOPSIS
.I ansi2knr
[--varargs] input_file [output_file]
.SH DESCRIPTION
If no output_file is supplied, output goes to stdout.
.br
There are no error messages.
.sp
.I ansi2knr
recognizes function definitions by seeing a non-keyword identifier at the left
margin, followed by a left parenthesis, with a right parenthesis as the last
character on the line, and with a left brace as the first token on the
following line (ignoring possible intervening comments). It will recognize a
multi-line header provided that no intervening line ends with a left or right
brace or a semicolon. These algorithms ignore whitespace and comments, except
that the function name must be the first thing on the line.
.sp
The following constructs will confuse it:
.br
- Any other construct that starts at the left margin and follows the
above syntax (such as a macro or function call).
.br
- Some macros that tinker with the syntax of the function header.
.sp
The --varargs switch is obsolete, and is recognized only for
backwards compatibility. The present version of
.I ansi2knr
will always attempt to convert a ... argument to va_alist and va_dcl.
.SH AUTHOR
L. Peter Deutsch <ghost@aladdin.com> wrote the original ansi2knr and
continues to maintain the current version; most of the code in the current
version is his work. ansi2knr also includes contributions by Francois
Pinard <pinard@iro.umontreal.ca> and Jim Avera <jima@netcom.com>.

CHANGE LOG for Independent JPEG Group's JPEG software
Version 9 13-Jan-2013
----------------------
Add cjpeg -rgb1 option to create an RGB JPEG file, and insert
a simple reversible color transform into the processing which
significantly improves the compression.
The recommended command for lossless coding of RGB images is now
cjpeg -rgb1 -block 1 -arithmetic.
As said, this option improves the compression significantly, but
the files are not compatible with JPEG decoders prior to IJG v9
due to the included color transform.
The used color transform and marker signaling is compatible with
other JPEG standards (e.g., JPEG-LS part 2).
Remove the automatic de-ANSI-fication support (Automake 1.12).
Thank also to Nitin A Kamble for suggestion.
Add remark for jpeg_mem_dest() in jdatadst.c.
Thank to Elie-Gregoire Khoury for the hint.
Support files with invalid component identifiers (created
by Adobe PDF). Thank to Robin Watts for the suggestion.
Adapt full buffer case in jcmainct.c for use with scaled DCT.
Thank to Sergii Biloshytskyi for the suggestion.
Add type identifier for declaration of noreturn functions.
Thank to Brett L. Moore for the suggestion.
Correct argument type in format string, avoid compiler warnings.
Thank to Vincent Torri for hint.
Add missing #include directives in configuration checks, avoid
configuration errors. Thank to John Spencer for the hint.

Some Windows system include files define typedef boolean as "unsigned char".
The IJG code also defines typedef boolean, but we make it "int" by default.
The IJG code also defines typedef boolean, but we make it an "enum" by default.
This doesn't affect the IJG programs because we don't import those Windows
include files. But if you use the JPEG library in your own program, and some
of your program's files import one definition of boolean while some import the
other, you can get all sorts of mysterious problems. A good preventive step
is to make the IJG library use "unsigned char" for boolean. To do that,
add something like this to your jconfig.h file:
/* Define "boolean" as unsigned char, not int, per Windows custom */
/* Define "boolean" as unsigned char, not enum, per Windows custom */
#ifndef __RPCNDR_H__ /* don't conflict if rpcndr.h already read */
