Sockets

TCP client and server

GenTCP simplifies TCP sockets. The listen function starts a server, and the connect function opens a client. Both return a socket object that you use with send and recv.

1> {ok, ListenPid} = gen_tcp:listen(4567, [binary, {packet, 1}]).

ok, #Port<0.0.0.0.4567

{ok, Socket} = gen_tcp:connect("127.0.0.1", 4567, [binary, packet, 1]).

ok
