Topics and semaphores in Ada95

Question

How to use streams in Ada95? What functions can I use to create, destroy, stop and start them?

How to use semaphores in this language?

Answer 1

Ada terminology for a stream is a "task". Ada does not have semaphores (as such) embedded directly in the language, but Googling for something like the “Ada semaphore” should appear in a lot of hits. AdaPower.com , in particular, talks a lot about parallel programming in Ada (and, for that matter, almost all kinds of programming in Ada).
