Re: luasocket udp multicast working example?

[Egil Hjelmeland <privat@...>]

To send to multicast just use sendto()

socket.udp():sendto('hello world', '239.192.1.1', 50005)

To receive, I found by reading the C -code:

s1 = socket.udp()
res, err = s1:setsockname('239.192.1.1', 50005)
res, err = s1:setoption("ip-add-membership" , { multiaddr = '239.192.1.1', interface = '10.0.0.10'})

An update to http://w3.impa.br/~diego/software/luasocket/udp.html would be nice...


Best regards
Egil

Hello,

can anyone show us a working example of usage for LuaSocket and its support for UDP multicast?

I've been googling quite extensively without any luck.

Thanks,
Valerio
