PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux

NAME

12       sched_rr_get_interval — get execution time limits (REALTIME)
13

SYNOPSIS

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

DESCRIPTION

20       The sched_rr_get_interval() function shall update the  timespec  struc‐
21       ture  referenced by the interval argument to contain the current execu‐
22       tion time limit (that is, time quantum) for the  process  specified  by
23       pid.   If pid is zero, the current execution time limit for the calling
24       process shall be returned.
25

RETURN VALUE

27       If successful, the sched_rr_get_interval() function shall return  zero.
28       Otherwise,  it shall return a value of -1 and set errno to indicate the
29       error.
30

ERRORS

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