      For more information about relationship chains, see Introduction to the Relationship Chain System.

      TIMFriendshipGetFriendProfileList

      This API is used to obtain the friend list.

      Prototype

      TIM_DECL int TIMFriendshipGetFriendProfileList(TIMCommCallback cb, const void* user_data);

      Parameters

      Parameter Type Description
      cb TIMCommCallback Callback for notifying whether the friend list is obtained. For more information about the callback function definition, see TIMCommCallback.
      user_data const void* User-defined data. The IM SDK only transfers the user data to the callback function cb without processing the data.

      Return values

      Type Description
      int If TIM_SUCC is returned, the API was successfully called. (The callback cb is called only when the API returns TIM_SUCC.) If other values are returned, the API failed to be called. For more information about the definition of each return value, see TIMResult.

      Note：

      The callback set by this API returns all friend profiles. For more information, see FriendProfile.

      TIMFriendshipAddFriend

      This API is used to add friends.

      Prototype

      TIM_DECL int TIMFriendshipAddFriend(const char* json_add_friend_param, TIMCommCallback cb, const void* user_data);

      Parameters

      Parameter Type Description
      json_add_friend_param const char* JSON string of the API parameter for adding a friend.
      cb TIMCommCallback Callback for notifying whether a friend is added. For more information about the callback function definition, see TIMCommCallback.
      user_data const void* User-defined data. The IM SDK only transfers the user data to the callback function cb without processing the data.

      Return values

      Type Description
      int If TIM_SUCC is returned, the API was successfully called. (The callback cb is called only when the API returns TIM_SUCC.) If other values are returned, the API failed to be called. For more information about the definition of each return value, see TIMResult.

      Note：

      Friend relationships are classified as two-way friends and one-way friends. For more information, see Adding friends.

      Example

      Json::Value json_add_friend_param;
json_add_friend_param[kTIMFriendshipAddFriendParamIdentifier] = "user4";
json_add_friend_param[kTIMFriendshipAddFriendParamFriendType] = FriendTypeBoth;
json_add_friend_param[kTIMFriendshipAddFriendParamAddSource] = "Windows";
json_add_friend_param[kTIMFriendshipAddFriendParamAddWording] = "I am Iron Man";
int ret = TIMFriendshipAddFriend(json_add_friend_param.toStyledString().c_str(), [](int32_t code, const char* desc, const char* json_params, const void* user_data) {
    if (ERR_SUCC != code) {
        // Failed to add a friend.
        return;
    }
}, nullptr);
