1. Never use <1> directly, there are constants in the kernel headers.
2. See http://www.xml.com/ldd/chapter/book/ch04.html#t1 how to use these
   constants and how to configure your system so that you can read the
   output in a log file.
3. Use dmesg to watch the kernel buffer quickly without needing to
   reconfigure something.

  Bernhard
