Each call to <code>process-send</code> sends one datagram packet (see <a href="input-to-processes">Input to Processes</a>), and each datagram received results in one call to the filter function. </p> <p>The datagram connection doesn’t have to talk with the same remote peer all the time. It has a <em>remote peer address</em> which specifies where to send datagrams to. Each time an incoming datagram is passed to the filter function, the peer address is set to the address that datagram came from; that way, if the filter function sends a datagram, it will go back to that place. You can specify the remote peer address when you create the datagram connection using the <code>:remote</code> keyword. You can change it later on by calling <code>set-process-datagram-address</code>. </p> <dl> <dt id="process-datagram-address">Function: <strong>process-datagram-address</strong> <em>process</em> +</dt> <dd><p>If <var>process</var> is a datagram connection or server, this function returns its remote peer address. </p></dd> +</dl> <dl> <dt id="set-process-datagram-address">Function: <strong>set-process-datagram-address</strong> <em>process address</em> +</dt> <dd><p>If <var>process</var> is a datagram connection or server, this function sets its remote peer address to <var>address</var>. </p></dd> +</dl><div class="_attribution"> + <p class="_attribution-p"> + Copyright © 1990-1996, 1998-2022 Free Software Foundation, Inc. <br>Licensed under the GNU GPL license.<br> + <a href="https://www.gnu.org/software/emacs/manual/html_node/elisp/Datagrams.html" class="_attribution-link">https://www.gnu.org/software/emacs/manual/html_node/elisp/Datagrams.html</a> + </p> +</div> |
