std::basic_stacktrace<Allocator>::max_size

From cppreference.com
 
 
 
 
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.

[edit] Parameters

(none)

[edit] Return value

Maximum number of elements.

[edit] Complexity

Constant.

[edit] 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.

[edit] Example

#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
