The term "Real-time OS" has no connection with keeping accurate clock time in the system clock. The subject of real-time OS is a big one, therefore it is best that we discuss it in a separate thread if at all. :) Suffice to say that the real-time behaviour of an OS has no connection with accurate system clocks. BTW, an OS as a whole (as in Red Hat or Solaris) is not real-time or non-real-time. Only the kernel is, really. The rest of the OS, i.e. the user processes, remain practically the same, except for some apps that one may write which do user-state things with the help of the real-time extensions of the kernel. Therefore, the correct term should probably be "real-time kernel" rather than real-time OS." :) Shuvam _______________________________________________ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd
