I don't think that was excetly what he was saying. But if it is, he's
incorrect. Since they are meant to interface with C code directly, OS
routines are usually imported into Ada programs *as*if* they were C routines.
The only problem with writing your code in Ada is that you will find their
interfaces annoyingly non-Ada like. I suppose you also have to be aware that
OS routines aren't always task-safe.
Again, if you aren't ever going to run these processes on separate processors
I would highly suggest using Unix IPC (shared memory or message queues)
rather than sockets (TCP/IP). IPC is a lot easier to interface to and use. On
the other hand, TCP/IP looks better on a resume'...
