Do you think we should leave this one exactly asis, and anyone wanting IPv6 must move to a new abstraction?<BR>
<BR>
<BR>
Or should we provide some partial source (in)compatibility but keep everything in interface Socket.<BR>
<BR>
<BR>
I do believe, btw, that code should work with either IPv4 or v6, or even for that matter IPX. Just pass strings along and let layers below you figure it out.<BR>
I wouldn't want to introduce Socket6 that only works with IPv6.<BR>
<BR>
<BR>
The likely abstraction therefore is Address = TEXT. <<<BR>
<BR>
<BR>
I'm also not sure, but my rough reading of IPv6 stuff is that you don't call socket() until after you resolve the string -- getaddrinfo returns a list of families, so you can't just pass one to socket() and be done. That is, the current separation of Create/Bind/Connect/Accept is a bit off. It can be preserved, but Create wouldn't actually call socket(), it'd just store stream or dgram and put off the rest till Connect/Bind/Listen/Accept (probably just two of the four, when I really know what does what..)<BR>
