Helper classes

hash<stacktrace_entry> (C++23)

 

Defined in header <stacktrace>
template< class CharT, class Traits > std::basic_ostream<CharT, Traits>&     operator<<( std::basic_ostream<CharT, Traits>& os, const std::stacktrace_entry& f );		(since C++23)

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

Parameters

os	-	an output stream
f	-	a stacktrace_entry whose description is to be inserted

Return value

os.

Exceptions

May throw implementation-defined exceptions.

Notes

Since std::string can only be outputted by std::ostream (not by e.g. std::wostream), it is effectively required that os be of type std::ostream&.

Example

Run this code

#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
