ansi2knr
ANSI2KNR(1) General Commands Manual ANSI2KNR(1)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 semi-
colon. 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The --varargs switch is obsolete, and is recognized only for backwards compatibility.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.
