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. Are there any means for either inspecting the contents of the trace (e.g. iterating over the frames and extracting things like the function name, offset, source file/line if available, etc.)? Alternatively, is there any way to control the formatting of the trace when it is inserted into a stream? If not, is the format platform-specific or in some common layout? Jason
