RTP_LOOKUP to lookup the current priority, -and RTP_SET to set the priority. -.Fa pid -specifies the process to be used, 0 for the current process. - -.Fa *rtp -is a pointer to a struct rtprio which is used to specify the priority and priority type. -This structure has the following form: -.Bd -literal -struct rtprio { - u_short type; - u_short prio; -}; -.Ed -.Pp -The value of the -.Nm type -field may be RTP_PRIO_REALTIME for realtime priorities, -RTP_PRIO_NORMAL for normal priorities, and RTP_PRIO_IDLE for idle priorities. -The priority specified by the -.Nm prio -field ranges between 0 and -.Dv RTP_PRIO_MAX (usually 31) . -0 is the highest possible priority. - -Realtime and idle priority is inherited through fork() and exec(). - -A realtime process can only be preempted by a process of equal or -higher priority, or by an interrupt; idle priority processes will run only -when no other real/normal priority process is runnable. Higher real/idle priority processes -preempt lower real/idle priority processes. Processes of equal real/idle priority are run round-robin. -.Sh RETURN VALUES -.Fn rtprio -will return 0 for success and -1 for all errors. The global variable -.Va errno -will be set to indicate the error. -.Sh ERRORS -.Fn rtprio -will fail if -.Bl -tag -width Er -.It Bq Er EINVAL -The specified -.Fa prio -was out of range. -.It Bq Er EPERM -The calling process is not allowed to set the realtime priority. Only -root is allowed to change the realtime priority of any process, and non-root -may only change the idle priority of the current process. -.It Bq Er ESRCH -The specified process was not found. -.Sh AUTHOR -The original author was Henrik Vestergaard Draboel - hvd@terry.ping.dk.
