21 The sched_rr_get_interval() function shall update the timespec struc‐
22 ture referenced by the interval argument to contain the current execu‐
23 tion time limit (that is, time quantum) for the process specified by
24 pid. If pid is zero, the current execution time limit for the calling
25 process shall be returned.
26
28 If successful, the sched_rr_get_interval() function shall return zero.
29 Otherwise, it shall return a value of -1 and set errno to indicate the
30 error.

33 The sched_rr_get_interval() function shall fail if:
