ErrFriendQuery
Description:
public enum ErrFriendQuery
Common error codes for friend state query functions.
Content:
Enum values:
- FRIEND_NOT_FOUND - The
friend_number did not designate a valid friend.
- NULL - The pointer parameter for
storing the query result (name, message) was NULL. Unlike the `_self_` variants of these functions, which have no effect when a
parameter is NULL, these functions return an error in that case.
- OK - The function returned successfully.
