std :: unique_ptr使用自定义删除器,参数很少

void my_free(int* p, int x, int y){
  std:: cout << x << " " << y << "\n";
}
int main()
{
    auto my_deleter = std::bind(my_free, std::placeholders::_1, 1, 2) ;
    auto my_lambda = [](int* t) { my_free(t, 3, 4); };
    std::unique_ptr ptr(new int, my_deleter);
    std::unique_ptr ptr2(new int, my_lambda);
    return 0;
}
