Example 8–5 Creating and Sending a Pnotice

	/*
	* Create and send a ToolTalk notice message
	* ttsample1_value(in int <new value)
	*/

	msg_out = tt_pnotice_create(TT_SESSION, “ttsample1_value”);
	tt_message_arg_add(msg_out, TT_IN, “integer”, NULL);
	tt_message_arg_ival_set(msg_out, 0, (int)xv_get(slider, 
	    PANEL_VALUE));
	tt_message_send(msg_out);

	/*
	* Since this message is a notice, we don't expect a reply, so
	* there's no reason to keep a handle for the message.
	*/

	tt_message_destroy(msg_out);

Example 8–6 illustrates how an orequest is created and sent when the callback routine for cntl_ui_hilite_button is called.

Example 8–6 Creating and Sending an Orequest

/*
 * Notify callback function for `cntl_ui_hilite_button'.
 */
void
cntl_ui_hilite_button_handler(item, event)
	Panel_item		item;
	Event		*event;
{
	Tt_message		msg;
	
	if (cntl_objid == (char *)0) {
		xv_set(cntl_ui_base_window, FRAME_LEFT_FOOTER,
		 “No object id selected”, NULL);
		return;
	}
	msg = tt_orequest_create(cntl_objid, “hilite_obj”);
	tt_message_arg_add(msg, TT_IN, “string”, cntl_objid);
	tt_message_callback_add(msg, cntl_msg_callback);
	tt_message_send(msg);
