.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The --varargs switch is obsolete, and is recognized only for 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.
