std::unordered_multiset::max_size
From cppreference.com
< cpp | container | unordered multiset
| size_type max_size() const;
|
(since C++11) | |
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.

[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
Run this code
#include <iostream> #include <unordered_multiset> int main() { std::unordered_multiset<char> s; std::cout << "Maximum size of a 'unordered_multiset' is " << s.max_size() << "\n"; }
Possible output:
Maximum size of a 'unordered_multiset' is 18446744073709551615
