NAME

13       sched_rr_get_interval — get execution time limits (REALTIME)
14

SYNOPSIS

16       #include <sched.h>
17
18       int sched_rr_get_interval(pid_t pid, struct timespec *interval);
19

DESCRIPTION

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

RETURN VALUE

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.
31

ERRORS

33       The sched_rr_get_interval() function shall fail if:
34
35       ESRCH  No process can be found corresponding to that specified by pid.
