std::dynarray::max_size

From cppreference.com
< cpp‎ | container‎ | dynarray

size_type max_size() const;
(since {std})

Returns the maximum number of elements the container is able to hold due to system or library implementation limitations, i.e. std::distance(begin(), end()) for the largest container.

Contents

[edit] Parameters

(none)

[edit] Return value

Maximum number of elements.

[edit] Exceptions

noexcept specification:  
noexcept
  

[edit] Complexity

Constant.

[edit] Notes

This value is typically equal to std::numeric_limits<size_type>::max(), and reflects the theoretical limit on the size of the container. At runtime, the size of the container may be limited to a value smaller than max_size() by the amount of RAM available.

[edit] Example

#include <iostream>
#include <...>
 
int main()
{
    std::dynarray<char> s;
    std::cout << "Maximum size of a 'dynarray' is " << s.max_size() << "\n";
}

Possible output:

Maximum size of a 'dynarray' is 18446744073709551615
