std::multimap<Key,T,Compare,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() = 461,168,601,842,738,790 = 0x666,666,666,666,666 q.max_size() = 384,307,168,202,282,325 = 0x555,555,555,555,555
