            of semaphores in the system, though setting it to a large
            value to mean 'all' is acceptable.
            Initially, only semaphores numbered 1 to this number exist;
            higher numbered ones must be created before use.
            It is only useful to initialize semaphores up to this number;

            matches the total number of semaphores specified."
