// unordered_multimap limits
#include <iostream>
#include <unordered_map>

int main ()
{
  std::unordered_multimap<int,int> mymap;

  std::cout << "max_size = " << mymap.max_size() << std::endl;
  std::cout << "max_bucket_count = " << mymap.max_bucket_count() << std::endl;
  std::cout << "max_load_factor = " << mymap.max_load_factor() << std::endl;

  return 0;
}

可能的輸出
max_size = 357913941
max_bucket_count = 357913941
max_load_factor = 1
