Sockets without networking (understanding how sockets work)
This talk is a discussion of sockets and how they are implemented, illustrated with an example that requires little or no understanding of TCP/IP networking. The talk will be a code walk through of the simplest socket implementation, the Unix Address Family of sockets (AF_UNIX or AF_LOCAL). Unix sockets use file descriptors in the Unix filesystem to set up inter-process communication between two applications on the same host. The underlying implementation is quite simple to understand and makes an excellent base from which to understand and implement more complex socket types such as those for the Internet Protocols (TCP/IP).
