[erlang-questions] Line Receiver example?

[Oscar Hellström]

Hi Jarrod,

I guess what you're looking for is the packet option for sockets. In
case you're using a TCP socket you can either open your listen socket
with the option {packet, line}, gen_tcp:listen(Port, [{packet, line}]),
or you can set it to line based parsing later by issuing
inet:setopts(Socket, [{packet, line}]). In case of UDP you need to open
the socket with gen_upd:open(Port, [{packet, line}]). inet:setopts/2
will also work for a UDP socket.
