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 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The --varargs switch is obsolete, and is recognized only for backwards compatibility.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 ansi2knr will always attempt to convert a ... argument to va_alist and va_dcl.
