Thank you guys for all your great help.  The first problem is solved.
There are, however, some more things I would like to clearify about
sockets.  All I need to do is to have communications between two
processes (which are spawned separately).  How does the processes know
where to connect to?  Also, I would like some form of interrupt-driven
mechanism to signal one process when a message arrives.  I don't want
to keep polling the socket for that will eat up cpu time.  Is there any
way to cause a process to sleep when the socket is empty and wakes up
when new messages arrive?  
Thanx for all your help.  By the way, we are running 4.3 BSD here.
I will get to the Primer on Interprocess Communications later.
