NAME¶

std::basic_stacktrace::max_size - std::basic_stacktrace::max_size

Synopsis¶

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
