#include <boost/exception/info.hpp>
namespace
boost
{
typedef error_info<struct tag_throw_function,char const *> throw_function;
typedef error_info<struct tag_throw_file,char const *> throw_file;
typedef error_info<struct tag_throw_line,int> throw_line;
#define BOOST_ERROR_INFO\
::boost::throw_function(BOOST_CURRENT_FUNCTION) <<\
::boost::throw_file(__FILE__) <<\
::boost::throw_line((int)__LINE__)
}
This macro is designed to be used with operator<< when throwing a boost::exception, to store information about the location of the throw statement. It can be chained with other error_infos in a single throw expression.
