HZ(9)                  NetBSD Kernel Developer's Manual                  HZ(9)


NAME

     hz -- system clock frequency


SYNOPSIS

     #include <sys/kernel.h>
     int hz;


DESCRIPTION

     hz specifies the number of times the hardclock(9) timer ticks per second.
     hz is hardware-dependent; it can be overridden (if the machine dependent
     code supports this) by defining HZ in the kernel configuration file (see
     options(4)).  Only override the default value if you really know what you
     are doing.
