Defined in header <stacktrace>
std::ostream& operator<<( std::ostream& os, const std::stacktrace_entry& f );
(since C++23)

Example

#include <stacktrace>
#include <iostream>
 
int main()
{
    for (const auto &f : std::stacktrace::current())
        std::cout << f << '\n';
}

Possible output:

0x0000000000402AA7 in ./prog.exe
__libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
0x00000000004029B9 in ./prog.exe
