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The --varargs switch is obsolete, and is recognized only for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