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 out-
    put, 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  iden-
    tifier 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.

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    The --varargs switch is obsolete, and is recognized only for backwards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