i'm learning udp with you. but repeating snippets from the above, the
following works for me (i seem to be both broadcasting and sending
directly, so i don't think it's completely correct, but at least i receive
something):
julia> s = UdpSocket()
UdpSocket(Ptr{Void} @0x0000000005bad480,1,Condition({}),Condition({}),
Condition({}))
julia> bind(s, IPv4(127,0,0,1), 9998)
true
julia> println(recv(s))
104
101
108
108
111

119
111
114

100
julia> s = UdpSocket()
UdpSocket(Ptr{Void} @0x00000000026c88d0,1,Condition({}),Condition({}),
Condition({}))
julia> bind(s, IPv4(127,0,0,1), 9999)
true
julia> Base.setopt(s, enable_broadcast=1)
julia> send(s, IPv4(127,0,0,1), 9998, b"hello world")
this is on linux, with a very recent julia 0.3 (built from git).
i think my previous problem was because i didn't bind before setopt.
the need for Base.setop() rather than simple setopt() is because this is
new code and the author wasn't sure whether it should be made public or
not. presumably it will change at some point. if you look at the source,
presumably setopy isn't included in the "exports" part of the module, at
the top.
hope that helps.
julia is still very much under development, so things sometimes aren't so
polished...
