NAME    [Toc]    [Back]

       hz - Global Variable: Stores the number of clock ticks per

SYNOPSIS    [Toc]    [Back]

       extern int hz;

DESCRIPTION    [Toc]    [Back]

       The hz global variable is set to the number of clock ticks
       per  second.  The value is useful for timing purposes. For
       example, if a kernel module wants to schedule a routine to
       be run in 2 seconds, you could use the following call:
        .  timeout(lptout, (caddr_t)dev, 2*hz);
