public member function

std::multiset::max_size

<set>
size_type max_size () const;
Return maximum size
Returns the maximum number of elements that the multiset container object can hold.

This is the maximum potential size the container can reach due to system or library implementation limitations.

Parameters

none

Return Value

The maximum number of elements a multiset container can have as its content.

Member type size_type is an unsigned integral type.

// multiset::max_size
#include <iostream>
#include <set>
using namespace std;

int main ()
{
  int i;
  multiset<int> mymultiset;

  if (mymultiset.max_size()>1000)
  {
    for (i=0; i<1000; i++) mymultiset.insert(i);
    cout << "The multiset contains 1000 elements.\n";
  }
  else cout << "The multiset could not hold 1000 elements.\n";

  return 0;
}


Here, member max_size is used to check beforehand whether the multiset will allow for 1000 elements to be inserted.

Complexity

Constant.
