* Name:sched_setscheduler
*
* Description:
* sched_setscheduler() sets both the scheduling policy
* and the priority for the task identified by pid. If
* pid equals zero, the scheduler of the calling task
* will be set. The parameter 'param' holds the priority
* sched_setscheduler() sets both the scheduling policy and the priority
* for the task identified by pid. If pid equals zero, the scheduler of
* the calling task will be set. The parameter 'param' holds the priority
* of the thread under the new policy.
*
* Inputs:
* pid - the task ID of the task to modify. If pid is zero,
* the calling task is modified.
* policy - Scheduling policy requested (either SCHED_FIFO
* or SCHED_RR)
* param - A structure whose member sched_priority is the
* new priority. The range of valid priority numbers is
* from SCHED_PRIORITY_MIN through SCHED_PRIORITY_MAX.
* pid - the task ID of the task to modify. If pid is zero, the calling
* task is modified.
* policy - Scheduling policy requested (either SCHED_FIFO or SCHED_RR)
* param - A structure whose member sched_priority is the new priority.
* The range of valid priority numbers is from SCHED_PRIORITY_MIN
* through SCHED_PRIORITY_MAX.
*
* Return Value:
* On success, sched_setscheduler() returns OK (zero). On
* error, ERROR (-1) is returned, and errno is set
* appropriately:
* On success, sched_setscheduler() returns OK (zero). On error, ERROR

* ESRCH The task whose ID is pid could not be found.
