* Name: sched_rr_get_interval
*
* Description:
* sched_rr_get_interval() writes the timeslice interval
* for task identified by 'pid' into the timespec structure
* pointed to by 'interval.' If pid is zero, the timeslice
* for the calling process is written into 'interval. The
* identified process should be running under the SCHED_RR
* scheduling policy.'
* sched_rr_get_interval() writes the timeslice interval for task
* identified by 'pid' into the timespec structure pointed to by
* 'interval.' If pid is zero, the timeslice for the calling process
* is written into 'interval. The identified process should be running
* under the SCHED_RRscheduling policy.'
*
* Inputs:
* pid - the task ID of the task. If pid is zero, the
* priority of the calling task is returned.
* pid - the task ID of the task. If pid is zero, the priority of the
* calling task is returned.
* interval - a structure used to return the time slice
*
* Return Value:
* On success, sched_rr_get_interval() returns OK (0). On
* error, ERROR (-1) is returned, and errno is set to:
* On success, sched_rr_get_interval() returns OK (0). On error,
