std::operator<<(std::basic_stacktrace) - cppreference.com (original) (raw)

Inserts the description of st into the output stream os. Equivalent to return os << std::to_string(st);.

[edit] Parameters

[edit] Example

#include #include   int main() { std::cout << "The stacktrace obtained in the main function:\n"; std::cout << std::stacktrace::current() << '\n'; []{ std::cout << "The stacktrace obtained in a nested lambda:\n"; std::cout << std::stacktrace::current() << '\n'; }(); }

Possible output:

The stacktrace obtained in the main function: 0# 0x0000000000402E7B in ./prog.exe 1# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6 2# 0x0000000000402CD9 in ./prog.exe   The stacktrace obtained in a nested lambda: 0# 0x0000000000402DDA in ./prog.exe 1# 0x0000000000402EB2 in ./prog.exe 2# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6 3# 0x0000000000402CD9 in ./prog.exe
