Wouldn't it make sense to combine boost:exception and boost:system (at least error_code and error_category stuff)? I find the error_code concept not only useful for system errors. Oliver
Are you proposing to define error_code and error_category tags as part of the Boost Exception library?
Yes - because it's related to error/exception passing. I'm using both libs in my projects.
As a user of both libs, what do you think is more appropriate:
- To have error_category and error_code tags in Boost Exception, or
- To use separate Boost Exception tags for each category, each tag identifying an integer error code?
Hmmm - my code looks like this: throw some_error() << BOOST_ERROR_INFO << boost::error_info< tag_error_code >( boost::system::error_code( errno, boost::system::errno_ec) ); I think there is no need for extra tags for error_code and error_category. I suggest that both classes and your exception framework should be in one boost library. Oliver
