Microsoft says: “Templates cannot be used with functions declared with __declspec (dllimport) or __declspec (dllexport).” (link).
What does this mean? Can I export a function which has a fully specialized template class reference as an argument?
That isn’t a
dllexport/dllimport-specific problem, its a general issue with templates – only one compiler currently implements the means toexporttemplates, see Comeaus template FAQ for details.Fully specialized templates however are distinct and concrete types and basically usable with the
__declspecextension, but there are limitations besides the entry you linked.Personally i’d mainly avoid templates in the interface here and only use them internally – i don’t see the what big benefits the time invested in working around the limitations give you.
