size_type max_size() const noexcept;		(since C++23)

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

Parameters

(none)

Return value

Maximum number of elements.

Complexity

Constant.

Notes

This value typically reflects the theoretical limit on the size of the underlying 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.

Example

Run this code

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

Possible output:

Maximum size of a 'basic_stacktrace' is 1152921504606846975
