+      * PARAMETERS

+      *              pointer to an instance of sem_t
+      *
+      * DESCRIPTION
+      *      This function waits on a semaphore. If the
+      *      semaphore value is greater than zero, it decreases
+      *      its value by one. If the semaphore value is zero, then
+      *      the calling thread (or process) is blocked until it can
+      *      successfully decrease the value or until interrupted by
+      *      a signal.
+      *
+      * RESULTS
+      *              0               successfully decreased semaphore,
+      *              -1              failed, error in errno
+      * ERRNO
+      *              EINVAL          'sem' is not a valid semaphore,
+      *              ENOSYS          semaphores are not supported,
+      *              EINTR           the function was interrupted by a signal,
+      *              EDEADLK         a deadlock condition was detected.
