[erlang-questions] How to solve the blocking accept call in a tcp_listener process ?

you could probably try using the active once option. Don't know if
this is what you need.

Open the socket like this,

{ok,Sock} = gen_tcp:listen(Port,[binary,{active,false}]),

Then when you need data,

socket_receive(Sock) ->
    {tcp,Sock,Bin} -> Bin

it allows the socket to send exactly one tcp message to the owner
process. Since it's in the mailbox, you can process it asynchronously.
