#include <dwc.h>BOOL DWC_SetFriendStatusCallback(DWCFriendStatusCallback callback,
void *param);| callback | Pointer to the callback function that notifies the user about changes to friend status. |
| param | Callback parameter. |
| TRUE | The configuration of the callback function was successful. |
| FALSE | The configuration failed because the FriendsMatch Library was not running. |
This function configures the callback function that is called when a friend's communication status changes. Refer to the description of the DWC_GetFriendStatus function for more details about the communication status.
This callback function is usually set as an argument of the DWC_UpdateServersAsync 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.
The callback function set here is called each time a friend's communication status changes.
