unordered_map::max_size
Gets the maximum size of the controlled sequence.
size_type max_size() const;
Remarks
The member function returns the length of the longest sequence that the object can control.
Example
// std_tr1__unordered_map__unordered_map_max_size.cpp
// compile with: /EHsc
#include <unordered_map>
#include <iostream>
typedef std::unordered_map<char, int> Mymap;
int main()
{
Mymap c1;
std::cout << "max_size() == " << c1.max_size() << std::endl;
return (0);
}
max_size() == 536870911
