NAME

       sched_rr_get_interval — get execution time limits (REALTIME)

SYNOPSIS

       #include <sched.h>

       int sched_rr_get_interval(pid_t pid, struct timespec *interval);

DESCRIPTION

       The  sched_rr_get_interval()  function  shall  update  the  timespec structure referenced by the interval
       argument to contain the current execution time limit (that is, time quantum) for the process specified by
       pid.  If pid is zero, the current execution time limit for the calling process shall be returned.

RETURN VALUE

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

ERRORS

       The sched_rr_get_interval() function shall fail if:

       ESRCH  No process can be found corresponding to that specified by pid.
