u64 DWC_CreateFriendKey( const DWCUserData* userdata );
Generates a friend registration key from the user data that will be exchanged with friends. Display the acquired friend registration key as a 12-digit base-10 numerical value.
In friend registration, after verifying the validity of the friend registration key entered by the user with the DWC_CheckFriendKey, create the friend data using the DWC_CreateFriendKeyToken function and add the created information to the friend roster.
Furthermore, assume that friend registration keys may sometimes be entered incorrectly; therefore, prepare an interface that allows users to reenter the friend registration key until it is accepted.
When the Nintendo Wi-Fi Connection has never been used, a friend registration key cannot be created, so make some kind of interface to create one after making a connection, or display a message with those instructions.
