+      *      This function indicates that the calling thread is
+      *      willing to give up some time slices to other threads.
+      *      NOTE: Since this is part of POSIX 1003.1b
+      *                (realtime extensions), it is defined as returning
+      *                -1 if an error occurs and sets errno to the actual
+      *                error.
+      *
+      * RESULTS
+      *              0               successfully created semaphore,
