DESCRIPTION

     ddi_get_lbolt() returns the value of lbolt where lbolt is an

     last system reboot.  This value is  used  as  a  counter  or
     timer  inside  the  system kernel. The tick frequency can be
     determined  by   using   drv_usectohz(9F)   which   converts
     microseconds into clock ticks.

RETURN VALUES

     ddi_get_lbolt() returns the value of lbolt.

CONTEXT
