# readability-uniqueptr-delete-release

Replace `delete <unique_ptr>.release()` with `<unique_ptr> = nullptr`. The latter is shorter, simpler and does not require use of raw pointer APIs.

    std::unique_ptr<int> P;
    delete P.release();

    // becomes

    std::unique_ptr<int> P;
    P = nullptr;

## Options

PreferResetCall

  If true, refactor by calling the reset member function instead of assigning to `nullptr`. Default value is false.

      std::unique_ptr<int> P;
      delete P.release();

      // becomes

      std::unique_ptr<int> P;
      P.reset();
