I don't know. Unless I've lost some bits in my memory I've not come
across that one before.
portable adj, code that compiles under more than one compiler

Ok While I am waiting for my book I thought I would ask about connect()
which is as I understand the next step after socket.
The first argument to connect is simple. The pointer to addr of type struct
is not so simple to me. Am I going to have to declare a type like thus,
struct sockadrr sock;
And use things like
sa_family_t family *fptr;
I really feel I am showing my ignorance here. Here is the page I am looking

Oops. I mean
connect(smtp,family.sock,... I just don't know. I have been studing these

Why would a book on network programming concentrate on AF_UNIX sockets?
They're only useful for inter-process communication, not networking.
I think there's some mention of them in the book, because they use the
same API, but 90% of it is about network programming.

Just because I am convinced that I am right doesn't necessarily mean I
actually am. But in absence of any factual statements about the topic,
I additionally claim that "people who use Solaris and don't use
AF_UNIX sockets for local IPC" will usually be people "who don't
understand IPC" (additionally qualified as 'local IPC among otherwise
unrelated processes') and that 'use of RPC' is a sure sign of a
confused mind :->.
