Resource Limits

RLIMIT_RTPRIO (2.6.12)

• Introduced so that unprivileged process can set real-time scheduling policies (SCHED_FIFO, SCHED_RR) using sched_setscheduler(2) or sched_setparam(2).
  
  
• If a process's RLIMIT_RTPRIO i is non-zero, then we can set a real-time scheduling policy for that process, with a priority up to the limit.
  
  
• Real-time priority range on Linux is 1 to 99.
  
  
• Linux specific.
