Newsgroups: comp.sys.sun Distribution: na Keywords: process class, realtime, realertime At an Sun OEM developer's conference in the spring of 1990, there was panel discussion which touched on some impending SunOS/SysVR4 functionality regarding "realer time" aspects of processes. As I recall, the plan was to allow classification of processes as either "Timesharing" or "Realtime"; Timesharing processes would be like the garden variety Unix process. They get pre-empted after their slice of CPU time. Realtime processes were to be prioritized (20 levels), and would be allowed to run until they blocked. I don't remember if a higher priority process became ready while another was running whether the current process was pre-empted. Sounded kind of interesting. I was wondering what the current state of this functionality is. Can't seem to find anything in the 4.1.1 manpages that refer to this. Is it in SVR4? Am I dreaming? Thanks (wishful thinking).
