std::unordered_multiset<Key,Hash,KeyEqual,Allocator>::max_size - cppreference.com (original) (raw)

| size_type max_size() const noexcept; | | (since C++11) (constexpr since C++26) | | -------------------------------------- | | ------------------------------------- |

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] Return value

Maximum number of elements.

[edit] Complexity

Constant.

[edit] Notes

This value typically reflects the theoretical limit on the size of the container, at most std::numeric_limits<difference_type>::max(). 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

Possible output:

p.max_size() = 1,152,921,504,606,846,975 = 0xFFF,FFF,FFF,FFF,FFF q.max_size() = 1,152,921,504,606,846,975 = 0xFFF,FFF,FFF,FFF,FFF
