NAME

hrtconfig − configure a RTC for use by the high resolution callout queue

SYNOPSIS

/usr/etc/hrtconfig devicename

DESCRIPTION

hrtconfig is meant to be called from /etc/rc.  hrtconfig will configure a real-time clock (RTC) device for use by the high resolution callout queue for the scheduling of events.  Using an RTC to schedule events on the high resolution callout queue provides a finer scheduling resolution than is available using the system 60HZ hardclock interrupt.  devicename is the device special file name of the RTC to be used exclusively by the high resolution callout queue.  Events may be scheduled on the high resolution callout queue using the nanosleep(3P4) POSIX 1003.4 library routine or the server_block(2) and client_block(2) system services.
