sched_rr_get_interval(2)

NAME
     sched_rr_get_interval - get round robin scheduling interval

C SYNOPSIS
     #include <sched.h>
     int sched_rr_get_interval (pid_t pid, struct timespec *interval)

DESCRIPTION
     sched_rr_get_interval stores the round robin scheduling interval at
     address interval for the process named by pid. If pid is set to zero,
     then sched_rr_get_interval obtains the interval for the calling process.

     sched_rr_get_interval will fail if one or more of the following are true:

     [EFAULT]       The address specified by interval is outside the range of
                    the caller's address space.

     [ESRCH]        The process named by pid does not exist.

     sched_setparam(2), sched_setscheduler(2), sched_yield(2)

DIAGNOSTICS
     Upon successful completion, a value of 0 is returned to the calling
     process. Otherwise, a value of -1 is returned and errno is set to
     indicate the error.
