__int sched_yield(void);__
!!DESCRIPTION
+A process can relinquish the processor voluntarily without blocking by calling sched_yield(2). The process will then be moved to the end of the queue for its static priority and a new process gets to run.
+Note: If the current process is the only process in the highest priority list at that time, this process will continue to run after a call to sched_yield(2).
