tipc:tipc_receive/4

tipc_receive(+Socket, -Data, -From, +OptionList) is det

Waits for, and returns the next datagram. Like its UDP counterpart, the data are returned as a Prolog string object (see string_codes/2). From is an address structure of the form port_id/2, indicating the sender of the message.

Defined options are:

as(+Type): Defines the returned term-type. Type is one of atom, codes or string (default).
nonblock: Poll the socket and return immediately. If a message is present, it is returned. If not, then an exception, error(socket_error(eagain, Message), _), will be thrown. Users are cautioned not to "spin" unnecessarily on non-blocking receives as they may prevent the system from servicing other background activities such as XPCE event dispatching.

The typical sequence to receive a connectionless TIPC datagram is:

receive :-
        tipc_socket(S, dgram),
        tipc_bind(S, name(18888, 10, 0), scope(zone)),
        repeat,
            tipc_receive(S, Data, From, [as(atom)]),
            format('Got ~q from ~q~n', [Data, From]),
            Data == quit,
        !, tipc_close_socket(S).
