That's an odd choice, since ipv4/ipv6 universally put things in network byte order in the sockaddrs. But since it's been made already, you want to still use network byte order internally in the stack. Because you're going to process more packets than you are going to be handling user sockaddrs. Translate the values to network byte order on bind() etc. calls and just be done with it. ------------------------------------------------------------------------------ Subversion Kills Productivity.
