NAME    [Toc]    [Back]

       lbolt - Global Variable: Is a periodic wakeup mechanism

SYNOPSIS    [Toc]    [Back]

       extern time_t lbolt;

DESCRIPTION    [Toc]    [Back]

       You  use  the  lbolt global variable  as a periodic wakeup
       mechanism. Wakeups are done on the lbolt variable once per
       second. For example, if a kernel module was polling for an
       event once per second, you could use the following code:
        .  sleep((caddr_t) &lbolt, PZERO);
