Re: luasocket-2.0-beta2: problems sending data with an unconnected udp socket

[Joseph Stewart <joseph.stewart@...>]

Okay... I spent a few minutes tracing things, but need some guidance...

It looks like the send() (in wsocket.c::sock_sendto()) fails with a
WSAEWOULDBLOCK error. Anyone savvy to why this is happening?

I can do the following to make things work:

s=socket.udp()
s:setpeername("10.3.64.36",13919)
s:send(string.char(160))

but that's inconvenient, and I don't think it works with broadcast datagrams.

Guidance appreciated!

Thanks for the wonderful community. I love Lua (anyone making bumper
stickers or t-shirts that say this?)
