You should understand what can be declared and initialised where. If
your history on comp.lang.c is anything to go by, you've a lot of
learning to go.

You need to learn that assignment statements can only appear inside
function bodies.

You can initialize global variables in the toplevel, but the
initializers have to be literals, they can't call functions like
socket() or bind() (C++ relaxes this limitation).

Damn. That really is a good thorough site yes thanks. Little more work that
what I expected but that's good for me. I guess I am going to have to write
something of type struct addrinfo and plug in the members. I was looking at
the tutorial on www.opengroup.org it was kind of confusing.
