It removes from a file both the directives and the +additional text that they delimit, while otherwise leaving the file alone. + +It is useful for avoiding distractions when studying code that uses +#ifdef heavily for portability: the author's original motivation was to +understand xterm's pty handling code. It can be used as a lightweight +preprocessor; for example the Linux kernel uses unifdef to strip out +#ifdef __KERNEL__ sections from the headers it exports to userland. You +can use unifdef with languages other than C; for example UIT, a publisher +in Cambridge, uses unifdef with LaTeX. |
