67      <p>Gets information about a message received in the previous communication.</p><p>After you receive a receipt notification using <a href="../../../nn/cec/CTR/GetCecRecvEventHandle.html"><CODE>GetCecRecvEventHandle</CODE></a>, you can use this function to, for example, check whether there is data addressed to the foreground application.<br /> This function can only get information about one message, even when multiple grouped messages are received.<br /> In addition, the obtained data does not include information about received data that was discarded because it was duplicated. The <a href="../../../nn/cec/CTR/CecNotificationData/Overview.html"><CODE>CecNotificationData</CODE></a> <SPAN class="argument">count</SPAN> value increments every time StreetPass data is exchanged. You can check for changes in this value to determine whether an exchange has occurred.</p></div>
