[usocket-devel] socket-connect and hostnames resolved to multiple addresses

Hi Chun, Alexey,

Now that USOCKET has UDP sockets and this question comes up, it's
probably time for me to explain how I envisioned the future of
USOCKET.

In my mind, early on with USOCKET when I didn't know it was feasible
to create UDP support on all platforms, I envisioned a USOCKET library
(which looked very much like what we have now) and a UUDP library. The
latter would implement the name resolution routines (a small DNS
client) missing in so many platforms, much like Allegro implements
one.

The above is also the reason I never exported the name resolution
routines from USOCKET and implemented USOCKET to take all forms of
IPv4 addresses known at that time.


Hope that adds to the discussion.


Bye,


Erik.
