Note that using anything other than SCHED_OTHER with priority 0 is only available to root users or after giving special permission to the executable with the setcap command line utility.

If a policy is selected which requires privaldges the user does not have, then a friendly warning will be displayed and the thread will still be set with the priority and scheduler inherited from the calling process.

  • policy – [in] SCHED_FIFO SCHED_RR or SCHED_OTHER
