Hi Geoff,

 

If I’m not mistaken, std:ystem_error was derived from Boost.

 

This being the case, you create an exception like this:

 

    #include <system_error>

    .

    .

    .

    throw system_error(errno, system_category(), “whatever message”);

 

AFAIK, you can also use generic_category() is you are dealing with POSIX error codes.

 

I hope this helps.

 

Regards,

Leo
