Finally, I've managed to do it:<br>
F = fun(P, Acc) -> case catch prim_inet:getfd(P) of {ok, FD}
-> [{FD, P} | Acc]; _ -> Acc end end.<br>
L = lists:foldl(F, [], erlang:ports()).<br>
Port = proplists:get_value(MyFD, L).<br>
<br>
Pay attention that prim_inet is internal module of VM, so it's usage
should be avoided in any production code!<br>

IIUC, {fd, integer() >= 0} allows to use the socket received
from socket() C function (or somehow else, but I can't propose
another way).<br>

If we managed to get the port (though I still don't know the way),
the controlling process can be obtained as following:<br>
{_, Pid} = erlang:port_info(Port, connected).<br>

I have a Unix file descriptor of Erlang VM process.<br>

Is there a way to receive an Erlang port of the socket?<br>

<div>See the {fd, integer() >= 0} option that various
