[det]tipc_send(+Socket, +Data, +To, +Options)

sends a TIPC datagram to one or more destinations. Like its UDP counterpart, Data is a string, atom or code-list providing the data to be sent. To is a name/3, name_seq/3, or port_id/2 address structure. See tipc_overview.txt, for more information on TIPC Address Structures. Options is currently unused.

A simple example to send a connectionless TIPC datagram is:

send(Message) :-
        tipc_socket(S, dgram),
        tipc_send(S, Message, name(18888, 10,0), []),
        tipc_close_socket(S).

Messages are delivered silently unless some form of congestion was encountered and the dest_droppable(false) option was issued on the sender's socket. In this case, the send succeeds but a notification in the form of an empty message is returned to the sender from the receiver, indicating some kind of delivery failure. The port-id of the receiver is returned in congestion conditions. A port_id(0,0), is returned if the destination address was invalid. Senders and receivers should beware of this possibility.
