            value to mean 'all' is acceptable.

            higher numbered ones must be created before use.
            It is only useful to initialize semaphores up to this number;

            operations are supported.

            C++ array initializer, between curly brackets.
            Ensure that the number of initializers here exactly
            matches the total number of semaphores specified."
