Or is the existence of locale_t somehow guaranteed by gnulib? If it is, then that's solved.Just wrap it in a typedef so we don't directly expose it in headers: #if HAVE_LOCALE_T typedef virLocale locale_t #else typedef virLocale void #endif
That's what I was talking about. We need this, but also a possibility to return error, so this needs to be an argument... And it's way more code that is there right now. I'm not saying NO to the change, I just that I like it like it's now (until more things need this treatment). So for others, feel free to propose changes as you like :)
