-      * DOCPUBLIC
-      *      This function tries to wait on a semaphore.
-      *
-      * PARAMETERS
-      *      sem
-      * 	     pointer to an instance of sem_t
-      *
-      * DESCRIPTION
-      *      This function tries to wait on a semaphore. If the
-      *      semaphore value is greater than zero, it decreases
-      *      its value by one. If the semaphore value is zero, then
-      *      this function returns immediately with the error EAGAIN
-      *
-      * RESULTS
-      * 	     0		     successfully decreased semaphore,
-      * 	     -1 	     failed, error in errno
-      * ERRNO
-      * 	     EAGAIN	     the semaphore was already locked,
-      * 	     EINVAL	     'sem' is not a valid semaphore,
-      * 	     ENOTSUP	     sem_trywait is not supported,
-      * 	     EINTR	     the function was interrupted by a signal,
-      * 	     EDEADLK	     a deadlock condition was detected.
