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
