std::basic_stacktrace<Allocator>::end, std::basic_stacktrace<Allocator>::cend

const_iterator end()  const noexcept;
(1) (since C++23)
const_iterator cend() const noexcept;
(2) (since C++23)

Returns the iterator pointing past the last entry of the basic_stacktrace.

This iterator acts as a placeholder; attempting to dereference it results in undefined behavior.

Parameters

(none).

Return value

The end iterator.

Complexity

Constant.

Example

#include <algorithm>
#include <iostream>
#include <stacktrace>
 
int main()
{
    auto trace       = std::stacktrace::current();
    auto empty_trace = std::stacktrace{};
 
    // Print stacktrace.
    std::for_each(trace.begin(), trace.end(),
                  [](const auto& f) { std::cout << f << '\n'; });
 
    if (empty_trace.begin() == empty_trace.end())
        std::cout << "stacktrace 'empty_trace' is indeed empty.\n";
}

Possible output:

0x0000000000402BA8 in ./prog.exe
__libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
0x0000000000402A29 in ./prog.exe
stacktrace 'empty_trace' is indeed empty.
