.TH ANSI2KNR 1 "19 Jan 1996"
ansi2knr \- convert ANSI C to Kernighan & Ritchie C
.I ansi2knr
[--varargs] input_file [output_file]
If no output_file is supplied, output goes to stdout.
There are no error messages.
.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.
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.
The --varargs switch is obsolete, and is recognized only for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.
L. Peter Deutsch <> 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 <> and Jim Avera <>.
