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.
