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(), [](constauto& 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.
