[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.60x0000000000402A29 in ./prog.exestacktrace 'empty_trace' is indeed empty.
