Hi all

I'll clarify my question as i seem to have failed to make it clear.

My point is: Isn't it wrong to use the term unix sockets for local
domain sockets? This isn't a tecnical question or a failure to
understand what sockets are, what varieties exist and for what
purposes each can be used (and what goodies each type provides). It's
a failure to understand why the term unix sockets is used to
designate local domain sockets.

The point in using the tcp/udp example is that contrary to popular
designation, the sentence "doing tcp/udp is impossible with unix
sockets because unix sockets are local domain sockets" is false. Unix
sockets are the general class. While it's true that local domain
sokets do not use tcp/udp, it's false (and this is a conceptual stand
not an everyday unix jargon use) that unix sockets = local domain
sockets.

Hierarchy

UNIX SOCKET {
local domain
ipv4/6
etc
etc
}

And this is the view that i would like you to tell me is right or
wrong (i'm not standing by it, just asking what you consider it to be).

Thanks for reading
