3) Support for linking multiple error tags in a single expression might be useful and help in standarizing errors throughout an application.
throw boost:::exception() << boost::error_info<tag_errorno,tag_filename,tag_size,tag_width>( (1,"output.txt",100,200);
Could you clarify what you mean?
Well, I could do something like this:
typedef boost::error_info<tag_errorno, tag_filename,tag_size,tag_width> error_t;
throw error_t(1,"output.txt",100,200);
If this error was common throughtout an application, this typedef would make the code more readable.
Tom, I need some more help in understanding what you are proposing. What exactly is error_t? It is confusing because the way you use it above, it appears that it's an exception type. At the same time, it makes reference to boost::error_info, which is _not_ an exception type (in the current definition of Boost Exception, error_info it is not something you throw.) Emil Dotchevski
