62<p>This function configures the callback function that is called when a friend's communication status changes. Refer to the description of the <A href="DWC_GetFriendStatus.html"><CODE>DWC_GetFriendStatus</CODE></a> function for more details about the communication status.</p><p>This callback function is usually set as an argument of the <A href="DWC_UpdateServersAsync.html"><CODE>DWC_UpdateServersAsync</CODE></a> function used in the friend roster synchronization process. Even when no friend roster synchronization process is needed, if there is a need to know the friend's communication status in real time, use this function to configure the callback function.</p><p>The callback function set here is called each time a friend's communication status changes.</p>
