There's very little use of AF_UNIX compared to AF_INET in the real world, and all books reflect that. They will cover what you need to know. Don't let UNIX as a word scare you. Very little of anything is unix specific, think of it as the source material for most of what you need to know on any platform.

Also, the socket API itself is not tied to either protocol or address families.

In your example you used 0 as the 3rd argument. Should I have done that? Or should I leave the port numbers the way they are? Bill |
