The continuous reception function for one-way messages allows the client to receive continuous one-way messages from the server. This function starts when the dc_clt_open_notification_s function is executed and terminates when the dc_clt_close_notification_s function is executed. Ordinarily, if the server sends a one-way message to the client when the client is not ready to receive one-way messages from the server, an error is returned. However, if the continuous reception function for one-way messages is used, no error is returned because the messages are stored in the TCP/IP queue. The messages leave the queue when the client issues the function that receives one-way messages. The following figure shows the processing flow for the continuous reception function for one-way messages.
