Real-time Class

The real-time class uses a scheduling policy with fixed priorities so that critical processes run in predetermined order. Real-time priorities never change except when a user requests a change. Privileged users can use the priocntl(1) and priocntl(2) interfaces to assign real-time priorities. For more information, see the priocntl(1) or the priocntl(2) man pages.

The scheduler manages real-time processes by using configurable parameters in the real-time parameter table, rt_dptbl. This table contains information specific to the real-time class. For more information, see the rt_dptbl(5) man page.
