This has nothing to do with the UNIX sleep() command. Unfortunately, Google doesn't realise this. I don't know how to tell Google it isn't, without giving it even more keywords which will match it. I guess I could just say: ------------------ #include unsigned int sleep(unsigned int seconds); sleep() may be implemented using SIGALRM; mixing calls to alarm() and sleep() is a bad idea. Using longjmp() from a signal handler or modifying the handling of SIGALRM while sleeping will cause undefined results. ------------------ Anyway, back to the README... diary0.8 is the latest version as at 15 April 2002. This contains all the GIFs, etc, that I use. See http://sleepdiary.sourceforge.net/ for more info. This is pretty irregular stuff; I don't think many people have felt a need to download it, so if you have any questions, don't hesitate to mail me at the address listed above.
