Is there interest in it? What functionality would you like to have in it?

Documentation is always helpful.

Yeep, that's currently missing :(

If in short:

namespace boost { namespace stacktrace {

class stacktrace { public: BOOST_STATIC_CONSTEXPR std::size_t max_symbol_width = 256; typedef boost::array frame_t;

stacktrace() BOOST_NOEXCEPT; stacktrace(const stacktrace& bt) BOOST_NOEXCEPT; stacktrace& operator=(const stacktrace& bt) BOOST_NOEXCEPT; ~stacktrace() BOOST_NOEXCEPT;

std::size_t size() const BOOST_NOEXCEPT; frame_t operator[](std::size_t frame) const BOOST_NOEXCEPT; };

template std::basic_ostream& operator<<(std::basic_ostream& os, const stacktrace& bt);

}}

So you can construct stacktraces, copy them and output them to streams:

std::cerr << stacktrace();

I think a library like this could be very useful for practical cross-platform development.

Years back I implemented an abstraction for this which I contributed to ACE (http://www.dre.vanderbilt.edu/%7Eschmidt/ACE.html) https://github.com/DOCGroup/ACE_TAO/blob/master/ACE/ace/Stack_Trace.h https://github.com/DOCGroup/ACE_TAO/blob/master/ACE/ace/Stack_Trace.cpp You might be able to use the implementations there as a starting point. -- Chris Cleeland
