I added Sys_RegisterShutdown years ago and never really did anything
with it: now any system that needs to be shutdown can ensure it gets
shutdown on program exit, and in the correct order (ie, reverse to init
order).
It seems qsockaddr's assumptions aren't necessarily portable, as OpenBSD
seems to be doing weird things with qsa_family. Even if that's not the
case, this is cleaner.
Well, really re-use the existing documentation, but make doxygen do
something with it. I'm not fully satisfied with the result, but it will do
for now, and getting more information on what the messages really mean will
help.
Here's a patch to NET_SendToAll() which was always
broken: it never skipped non-connected clients.
Depending on the compiler, it would wait the whole
5 seconds of its blocktime before it gave up.
While there, changed its blocktime argument to
double (the comparison is against a double.)
