:- use_module(library(socket)).(can be autoloaded)
as(Type)option of udp_receive/4. The are interpreted differently though. No Type corresponds to CVT_ALL of PL_get_chars(). Using atom corresponds to CVT_ATOM and any of string or codes is mapped to CVT_STRING
|CVT_LIST, allowing for a SWI-Prolog string object, list of character codes or list of characters. Finally,
termmaps to CVT_WRITE_CANONICAL. This implies that arbitrary Prolog terms can be sent reliably using the option list‘[
encoding(utf8)])`, using the same option list for udp_receive/4.
send(Host, Port, Message) :- udp_socket(S), udp_send(S, Message, Host:Port, ), tcp_close_socket(S).
A broadcast is achieved by using
prior to sending the datagram and using the local network broadcast
address as a ip/4 term.
