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 possible 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  con-
     catenates 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  func-
     tion header.
          - String literals whose concatenation requires  rewrit-
     ing  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     The --varargs switch is obsolete, and is recognized only for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.
