A little criticism:
   write(file, read(file, size));
truncate by reading/writing is not good sample at least for official docs. It is not efficient. You can use POSIX truncate or _chsize Windows system calls for truncation to specific length. For zero it is simpler: open("file", "w+");

In Java world you can write OutputStream out = new BufferedOutputStream(new FileOutputStream(fileName), BUF_SIZE);
It is not clear how to combine OutBuffer and write in such way.
