Re: [Boost-users] [exception] array tags

Hi, I have another question regarding the exception library. I would like to use the BOOST_THROW_EXCEPTION() macro, but also add some tags of my own at the throw site. How do I do this? How would i rewrite the below? typedef boost::error_info std_range_which; throw boost::enable_error_info(std::out_of_range("Matrix -=: Inputs do not have same shape")) << std_range_which(Rows()!=M.Rows()? "row" : "col"); Simply doing BOOST_THROW_EXCEPTION(std::out_of_range("Matrix -=: Inputs do not have same shape")) << std_range_which(Rows()!=M.Rows()? "row" : "col"); does not work, nor does BOOST_THROW_EXCEPTION(std::out_of_range("Matrix -=: Inputs do not have same shape") << std_range_which(Rows()!=M.Rows()? "row" : "col")); Thank you! Diederick
