This section describes the timing facilities that are available for real-time applications under SunOS. Real-time applications that use these mechanisms require detailed information from the man pages of the routines that are listed in this section.
The timing interfaces of SunOS fall into two separate areas: timestamps and interval timers. The timestamp interfaces provide a measure of elapsed time. The timestamp interfaces also enable the application to measure the duration of a state or the time between events. Interval timers allow an application to wake up at specified times and to schedule activities based on the passage of time.
