std::basic_stacktrace
| 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.

[edit] Parameters
(none)
[edit] Return value
The end iterator.
[edit] Complexity
Constant.
[edit] Example
Run this code
#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.
