std::unordered_multiset::max_size

size_type max_size() const noexcept;
Return maximum size
Returns the maximum number of elements that the unordered_multiset container can hold.

This is the maximum potential number of elements the container can hold due to system constraints or limitations on its library implementation.

Parameters

none

Return Value

The maximum number of elements the object can hold as content.

Member type size_type is an unsigned integral type.

// unordered_multiset limits
#include <iostream>
#include <unordered_set>

int main ()
{
  std::unordered_multiset<int> myset;

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

  return 0;
}


Possible output:
max_size = 536870911
max_bucket_count = 536870911
max_load_factor = 1

Complexity

Constant.

Iterator validity
