RedHat 9 (Linux i386) - man page for ansi2knr (redhat section 1)

ANSI2KNR(1)			     General Commands Manual			      ANSI2KNR(1)

NAME
       ansi2knr - convert ANSI C to Kernighan & Ritchie C

SYNOPSIS
       ansi2knr [--filename filename] [input_file [output_file]]

DESCRIPTION
       --filename  provides  the  file	name  for  the	#line directive in the output, overriding
       input_file (if present).

       If no input_file is supplied, input is read from stdin.

       If no output_file is supplied, output goes to stdout.

       There are no error messages.

       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  possi-
       ble  intervening comments).  It will recognize a multi-line header provided that no inter-
       vening 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.

       ansi2knr also recognizes adjacent string literals and concatenates them.

       The following constructs will confuse it:
	    - Any other construct that starts at the left margin and  follows  the  above  syntax
       (such as a macro or function call).
	    - Some macros that tinker with the syntax of the function header.
	    -  String  literals whose concatenation requires rewriting their contents; e.g. "ab "
       "07c" is concatenated to "ab 07c", which is not correct.

       The --varargs switch is obsolete, and is recognized only for backwards compatibility.  The
       present	version of ansi2knr will always attempt to convert a ... argument to va_alist and
       va_dcl.

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>, Jim Avera  <jima@net-
       com.com>, and Paul Eggert <eggert@twinsun.com>.
