DESCRIPTION

       sched_setscheduler() sets both the scheduling policy and the
       associated parameters for the thread whose ID is specified in pid.
       If pid equals zero, the scheduling policy and parameters of the
       calling thread will be set.  The interpretation of the argument param
       depends on the selected policy.  Currently, Linux supports the
       following "normal" (i.e., non-real-time) scheduling policies:

       SCHED_OTHER   the standard round-robin time-sharing policy;

       SCHED_BATCH   for "batch" style execution of processes; and

       SCHED_IDLE    for running very low priority background jobs.

       The following "real-time" policies are also supported, for special
       time-critical applications that need precise control over the way in
       which runnable threads are selected for execution:

       SCHED_FIFO    a first-in, first-out policy; and

       SCHED_RR      a round-robin policy.
