...one of the most highly
regarded and expertly designed C++ library projects in the
world.

#include <boost/exception/errinfo_nested_exception.hpp>
#include <boost/exception/error_info.hpp> namespace boost { typedef ---unspecified--- exception_ptr; typedef error_info<struct errinfo_nested_exception_,exception_ptr> errinfo_nested_exception; }
This type is designed to be used as a standard error_info instance for transporting (in exceptions deriving from boost::exception) an exception_ptr to an exception nested into another exception.
