Question C & TCP question: AF_INET vs AF_UNIX

Greetings!

I am attempting to write a *basic* network client in C. I have manage to create a socket but I have doubts as far as using AF_INET vs AF_UNIX.

At the present time, my client runs with AF_INET. Is AF_UNIX faster across hosts using the same OS flavor (Red Hat)? What is the difference between the two families?Smilie

I have found a post from 6 years ago asking the same question ( https://www.unix.com/security/8426-af...html#post29544 ) but it was never answered.

Any help is welcome. Thanks!

Al.
